Description: Transforming O&P with Digital Workflows and 3D Solutions

Transcript for "Transforming O&P with Digital Workflows and 3D Solutions": Thank you, everyone. Thanks for joining us for this exciting webinar today on transforming orthotics and prosthetics with digital workflows and three d. So for today's webinar, we're gonna start with a introduction into the industry opportunities in orthotics and prosthetics. We're gonna go through a short introduction of our workshop. We're gonna touch base on why, additive manufacturing has become an impactful tool in the orthotics and prosthetics industry. And through that, we're gonna start with the steps that are involved in this process. So starting out with a scanning slash design, three d printing step that comes next with post processing, as well as assembly, and also walk through for a patient experience. And just like any other session, we're gonna wrap it up with exciting question and answers at the end. To introduce you to the great team that are here today with us, I'm gonna start with myself. My name is Alireza Pasha, and I'm an enterprise account executive at GoEngineer. I manage, the orthotics and prosthetics as well as health care industry in Canada. We have Hardik Patel, our application specialist at GoEngineer. We have Richard Cromwell, our senior application engineer at GoEngineer. We have David Johnson, application engineer from HP, Emilie Simpson, our senior application engineer at DyeMansion, and our fellow friend, Dan Defonseca, our prosthetics research designer at Atlantic Clinic for Upper Lin. So, thanks everyone for joining us. So let's get it started. So to give everyone a bit of background on why we are here and why there is a massive growth opportunities within the three d printing industry in the health care markets, there are some numbers that are worth, putting into consideration. First one being that global three d printing in healthcare market is anticipated to witness a CAGR up to 20% through 2023 to 2030. We're almost halfway there and the growth is definitely there. And with that, North America leads the global three d printing in the healthcare market and it is anticipating to reach to 5,600,000,000 by 2030. So what's driving the change and why is there so much effort in digitalizing the orthotics and prosthetic industry? Well, there are a few big drivers. First of all, the traditional fabrication is very labor intensive and also is pretty prone to human error. The final parts and final devices that are created are not digitized. So if it breaks or if it needs to be rebuilt again, it's gonna be a little bit different. There are some challenges when it comes to, scalability. When you wanna grow, you need bigger space, and skilled technicians are also required that that slows down the, traditional scalability within this industry. The other part that's a little bit hidden, for people outside of the industry is that this process creates high volume of vase that also requires a storage of space for keeping some patterns in inventory. One of the recent changes that have been happening in this field is that there has been a shortage of a skilled technician that, can actually do the job. It takes years of experience and a specific skill set that makes you a great orthotist or prosthetist. And lastly, the demographic changes. There are, common diseases that are leading to increased number, of patient that will need care when it comes to orthotics and prosthetics devices. So just again, do a quick recap of what you would expect throughout this presentation. We're gonna walk you through the scanning process, how to design proper devices, and if you're using filament, deposition modeling or FFF systems, how you do design validation with check sockets. Then we go through means of production through three d printing, post processing, and again, final assembly and also patient fitting. And with that, I'm I'm gonna hand it off to my colleague, Hardik, who's gonna take us, kick us off with the scanning step. Hey, everyone. So the first step in, our, workflow here is three d scanning. Here's where we capture the, the lens or the cast using our three d scanners. For custom AFOs, orthotics, prosthetics, this is the first main step, and that's where we like to represent our tech. So here, at the bottom of the screen, you're looking at two Artec scanners. The one on the left is the Artec EVA. That's a long standing workhorse in this department. And on the right is the Artec Leo, which is fully wireless. No laptops, no cables, nothing with you. They both capture both geometry and texture, so you will have texture and geometry at the same time. And this is very important in our OMP workflow, which we'll get to in the next slide. With the LEO, the touch screen shows you the exact surface that you're capturing. So you can see right away what spots you're missing, what areas you need more scanning, and you could just get right to it. So this helps build a really fast, accurate capture, whether you are with a patient at a clinic or if you are just capturing a cost. So the... These scatters are pretty good with this workflow. Yeah. Here we can see, the two methods of capture. On the left, you can see that we are scanning the patient directly. This takes about two to five minutes, a general just a scanning process. And on the left side, you can see we are scanning directly, so there's no need for cars. We could just go straight from scanning the patient to your digital workflow in terms of modeling. You also are able to capture the, true soft tissue shapes and also the natural posture, which a cast can sometimes dissolve. On the right side, you can also stick to the... Your traditional, method of, scanning a cast or an impression. Nothing changes on how you work with the patient, but you're just digitalizing all the impressions so everything can be maintained in the digital world with your design process next. Now here's we can talk of... Here's where we can talk about why texture matters. So clinicians like to mark trim lines or landmarks along these cast or on the patient, skin, to, help with the digital modeling or even the cutting process. So to have these, impressions, which are basically textures on your scanning object, you need a scanner that captures both geometry and textures. Right? With the I tect scanners, that is possible so you don't have to guess where your trim lines are on your digital data. Now at the bottom of the screen, you can also see our workflow again. So first step was scanning, which we talked about right now, and the next step would be design software where we could talk about leo shape and then HP Printing and then that mention, post processing, dyeing, and all those fun stuff. So the next step here is the design software at LeoShape, which will be covered by Richard Cornwell. And, yeah, here's where we'll discuss about designing all the o and p related objects. Hi there, everybody. My name is Richard Cromwell. I've been, here for about seven years as a senior application engineer where I, work at GoEngineer as the biomedical and dental three d printing applications specialist. So today, I'm going to briefly introduce you to an innovative OMP industry specific device, design solution, called LeoShape. And it's powered by, Leopoli's cutting edge CAD three d engine. So LeoShape provides a scalable and modular solution to simplify and automate the design of custom orthotic and prosthetic devices. So what's the digital workflow all about and why are we gonna do it? Well, what we're trying to do is provide, intuitive application specific software, with intelligent automation tools that are industries... They have industry specific features. And the LeoShape platform, like, simplifies a really, complex workflow and improves patient outcomes over time. And it also will reduce the time to delivery. So whether you're looking for an end to end solution or or only, like, specific modules, and I'll talk about that in a little bit, the LeoShape, that you can get via GoEngineer, We can provide support, and data collection, optimization of your designs, personalization of the devices, the three d printing, the manufacturability of them. And then ultimately, we wanna deliver a high quality result, at an affordable cost. So Lioshape provides cutting edge three d design tools, tailored specifically for, O and P professionals. It does, essentially a direct from three d scan workflow. It has a series of custom editors and so that are anatomy and application specific. And each editor is gonna give you the freedom to create personalized orthotic and prosthetic designs that are tailored to the unique, patient needs. And so there's not really, a bunch of fixed templates or restrictions. They give you customizable templates that you can use your expertise and your preferences, and the power of LeoShape to make fully customizable three d, designs. And and and the idea is so that you can get a repeatable workflow. There is support also for nonstandard, OMP design and experimental applications, which is I think is really neat. And the files that are generated in the software are easy to export for rapid prototyping and digital manufacturing. Another thing that I really like about these guys, is that, they're actively involved in the voice of customer and listening to you as the clinicians, as the practitioners, and then bringing back, features that you want in... Directly into the software. We had a meeting today actually with with Leo Shaper. They gave a fantastic training to a to a hospital, staff. And, but at the end, part of the part of the things that they wanna talk about is is listening to you and incorporating, those features directly into their software. So why LeoShape specifically? So LeoShape is pretty great. I mean, it's exciting. They have, it's a web based solution. So it's not like something that you're gonna run locally. And this is important because, you know, a lot of the functionality and features that LeoShape has, if you think about them and you try to run them locally, you find out pretty quickly that they're computationally intensive. They take a lot of processing power, in the back end. Being able to run it on a web based app means that you're not bogging down your system with that. It's easy to integrate into your existing analog workflows. And so it's built for the OMP, professional from the ground up. And and it shows during, the ease of use and how, and we'll talk about it in a second how you can, like scan molds and be able to, basically put it in CNC mode versus three d printing. It's white label ready. This is important because, you know, you... We want to have, a professional appearance to our user interface and applications. And LeoShape is great about, customizing the UI, whether it's adding your logo and your specific designs even into the auto select buttons that that you can use. It is an AI supported system, and so it is, very intelligent and makes a lot of the automated, processes a lot easier. And, like... And it is an intuitive UI. That that is something I wanna impress. This isn't like, you know, trying to design something in SolidWorks where you're starting from scratch and using, like, parametric modeling. This is a workflow, a CAD workflow that is specifically designed for the applications and the devices that you guys are gonna be interested in making. So we... There's different modules inside of LeoShape. Leo Insole enables professionals to create perfectly fitted insoles using advanced three d modeling tools. Its intuitive interface supports a high level of customization while automating repetitive tasks, saving time, and enhancing accuracy. The... They have, like, automated arch and and heel correction tools, comprehensive material customization options. So if you're printing in TPU, you can, leverage your design specifically for that material versus printing, say, like in nylon 12. And there's, seamless integration into three d scanning devices like the one that, Hardik showed just previously. Here's a quick little, software demonstration where after uploading our foot scan and establishing, the orientation, we can parametrically customize the insole design just by using these little sliders and toggle switches. We can start with a template that has easily to change parameters like length and width. And then we can also do things like adjust shell thickness, increase heel cup height, or reinforce the medial arch. We can even add features like Morton extensions, cutouts, reinforcements, and a whole bunch of other handy features. So one of my favorite functions inside a Leo Insole is its ability to quickly generate complex conformal lattice structures. And these are ideal for three d printing on powder bed fusion technologies and TPU. And we can control the type of lattice that's generated, the lattice cell size, and even add things like a top cover. They even have the ability to add sidewalls now. And so you can quickly generate unique complex, topology. And like I said, if I tried to do this locally on my computer, this is one of those things where I'd have to walk away from my computer and go grab a cup of coffee. Because the, computational load is outsourced essentially to the web, it makes it so that it's able to generate this complex organic geometry very, very quickly. So LEO AFO is built to streamline the design of ankle foot orthotics and precise, it uses very precise three d editing tools. And so whether you're working on pediatric cases or adult patients, the platform enables accurate designs that deliver exceptional comfort and functionality. And so you get function... Things like, adjustable support for, alignment and movement correction. And so like you can add channels very easily or corrugation. They have preloaded templates, for faster design workflows. And that includes like things like hinged AFOs or dual layer AFOs. We're going to be printing the SMO out of, say like TPU and then the outer shell layer in nylon 12. And it also offers real time simulations to ensure proper fit and function. Okay. The workflow is really easy. You'd like log in. You can do it from anywhere because it's a web based application. You can upload your foot and leg scan. It will clean the scan, so do like your mesh edits. You will apply the landmarks denoting like where the anatomy is on the foot and the ankle. Then you're going to do your mesh edits and, add your three d trim lines, and then you can basically send it to the printer after that. Oops. Sorry. So clinical input for LEO AFO could be many different things. Of course, you can directly scan, your patient. You can also scan a plaster model, or an interior calf scan. The software walks you through a very quick semi automated process of identifying landmarks on the scan for the orientation of the anatomy. And you can also do mesh edits like truncation, of the model and filling up of the holes to ensure that you have the scan data that you... Just like you want it before proceeding with the orthotic design. And so, Leo AFO also allows us to make desired minor adjustments to the anatomical positioning before we essentially start working with the model like we would with a layup tool. And we can strategically add or remove material just like you would with a plaster model, and designate areas of additional support or relief. Oh, that does a really good job. You can also flare out the front portion of the model to be able to allow the device, to open easily and make any other adjustments before applying any number of a range of customizable built in preset AFO designs. And so we can easily adjust trim lines, position, different types of perforations. And we can do a lot more than that before quickly generating the geometry of the AFO itself. And look how fast that did that. Like, I use other applications, and that's another one of those situations where you'd be going to grab a cup of coffee and you can't just do it so quickly. LEO SPINAL allows you to design spinal braces. And it combines, the structural integrity, of, you know, nylon 12 with, patient comfort. And so from scoliosis braces to custom body jackets, LEO Spinal delivers precision with flexibility in every project. And so it gives you automatic spinal curve adjustments and corrections, kind of like with the anatomical corrections that we just saw a minute ago. Patient specific customization with intuitive three d tools and then output ready design. So ready to go for a quick manufacturing. The workflow is pretty similar. You're gonna upload your torso scan. You're gonna clean the scan up. Use the x-ray overlay tool. I'll show you in a second. Do any of the bending and the twisting that you need to do. Do your three d design, project your tram lines, and then send it to the printer. And so this short clip shows the X-ray being projected on top of the torso scan. And then the X-ray is projected onto the three d scan. Then you can use, and proceed to the design tab and project your trim lines and then generate the device to see how it looks. So it's a pretty easy workflow. And, if you want any more information on, LeoShape, this is a great place to go. We have a website set up for it. And if you'd like to connect with me on LinkedIn, you can just connect that, click that little icon and, take a picture of it, and let's, let's connect. Okay. Next, we're gonna go to David Johnson from HP who's gonna talk about, actually converting these digital designs into three d printed devices. Beautiful. Thank you, Richard. So again, my name is David Johnson. I'm a application engineer for HP. I've been with HP for about five years and then in the three d printing space for a little over a decade. So HP's technology is multi jet fusion or MJF. If you think of like the core competency of HP, it's thermal ink jet heads printing ink onto paper. So we're using those same ink jet heads except now we're putting an agent onto a fresh layer of powder. So the animation kind of shows high level how we're doing our printing. As the coater goes over here, it'll put down a fresh layer of powder plastic. The carriage will go over and we'll have our inkjet heads in there. So it's going to lay down a fusing agent and a detailing agent. That fusing agent is going to absorb heat from that carriage. That's what actually melts the parts together. Detailing agent kind of borders that fusing agent. It's more of a thermal buffer, so making sure things don't get too hot or over fusing in certain areas. The important thing in the process is it's an area based print. So, regardless of how many pieces you have in the XY slice, it's going to do it all in a single pass versus like point based like you might see with some other three d printing technologies. And with that, we're able to get high throughput but also consistent production, which is important for things like assembly and other aspects after the part is printed. So, we're going over the full workflow with our ecosystem. In the middle, you saw our printer, but some other pieces that are important to know. We have our build unit, which is basically our build platform. That's where all the parts are being printed. On the left, we have our processing station. This is handling all the materials, so we have a high recycle ratio. So it's going to be taking recycled powder, fresh powder, mixing it, putting it into the build unit, and then also reclaiming the unused powder within the system after everything's done. The equipment on the right, it's all automation equipment. It's not necessarily for the ecosystem, but as you scale up with our technology, there are some bottlenecks, and these pieces of equipments help it be a little more streamlined production process. So we do have a pretty big material portfolio of different powders, but within like the o and p space, there's only a few that are heavily utilized. PA 12, PA 11 for our rigid materials and then mainly for pediatrics or anything that wants like a more vibrant color, we have to get a lighter platform. So we have our PA 12 white and light gray. Those are really good for dyeing those vibrant light yellows and blues that Emilie will talk about. Polypropylene, so all those are more for the rigid, more force type of devices like AFOs or sockets. On the right, we have our flexible elastomers. We have a few different TPUs. These are usually for inners or even things like SMO or inkle gauntlets can be printed in this. We do have a lot of devices that will print both types of elastomer and rigid and kind of combine them into the final device. Rigid went over a few different options, but here's a few more. Photolithotics are... We are getting a lot of throughput with those. Cranials, we're the only technology right now that's three d printing these. It's a pretty rigorous regulation process, but we're... We have a lot of companies that are doing cranials right now, and then a few other devices that you can kinda see from there. So if you take Richard Cromwell last step of having that final part device and then now we're starting the first type of the print, we are basically trying to fill up this build platform as best we can. So our build platform is three eighty millimeters by two eighty four by three eighty. And when we print, we wanna fill this space effectively. That's how we get cost effectiveness out of the process. And with that, it's kind of the same. There's things called nesting softwares. So we would put all the devices we wanna try to print in that run and do a few parameter settings, hit go, come back. It takes a few minutes, and then we have a build like this ready to send to the printer. Alright. So this will be a little more detailed than that first animation you saw, but printing process is the same. We're putting agents down. But this will actually show some of the print heads with it jetting out as you see there. So this is what's happening underneath the carriage as it goes through. And an important thing, when you go into that nesting stage for the printing is the packing efficiencies. So when we do a full build, you're basically prepaying for all the fresh powder. So it might be 10%, 20% based on the material ratio, mix ratio. And this is not a technology where we're gonna print one part. We wanna do high volume, high throughput, and that's how we get the cost effectiveness because whether you put one part or a 100, we're basically paying the same amount of that fresh powder cost. So we try to allocate that towards more parts, and that's how we get, a cheaper printing process overall. So once we print, full print takes about twelve hours and then anywhere from twelve to twenty four hours to fully cool, and we have to remove all the unused powder in the build platform. We're able to reclaim it and that becomes recycled material for the next build. You can see there's a little bit of residual powder left on the part. So from HP's equipment, like this is our last stage, but you still have to do some type of media blaster, to remove the residual powder and get what I would call our final raw part. And Emilie will go into this a little bit, but that'll be the final step in this entire process. So the equipment we just went over was our production, equipment, and one of the challenges we've had is it's expensive, it's relatively large, and the high throughput is usually too much for most customers just getting started. So next year, early twenty twenty seven, we have a 1,200 coming out and I'm very excited about this. This will be a lot easier entry point for a lot of customers interested to kind of go into this direction. The system is 60,000 US, so with the conversion rate, it's about 84,000, 85,000 Canadian dollar range. It's about 12 liters, so three twenty by 165 by two thirty. And print time takes about twelve hours to print, five and ten hours to cool. So you're able to do a full build per business day. This will be launching with PA 12. The intent is to have our full material portfolio available for the system, but we're gonna be launching them, just to make sure everything's looking good before it's officially released. So we'll start with PA 12. We're probably gonna have another two or three materials available by the end of twenty twenty seven. So I'm excited about this. I think we got a lot of interest in it for our O and P customers. So hoping we can get more adoption and more interest bringing this in house with this system moving forward. And then from here, we're gonna take it over to Emilie Simpson from DyeMansion. So she'll take our raw parts, and then we'll make them to an actual finished part from there. Alright. Hello, everyone. My name is Emilie Simpson. I am a senior application engineer at DyeMansion. I'm excited to talk about o and p. My background is in biomedical engineering with the bulk of that within orthotics and prosthetics, so we're speaking the same language with the same excitement. Today, I'm gonna cover what DyeMansion does. DyeMansion does post processing. So you can think of this as what can I do to customize my part after it's been three d printed? So to give you a summary of what DyeMansion does, so we are a post processing company mostly focusing on powder bed technologies, so... Such as HPMJF. We also do work with other powder bed technologies. But in summary, we focus on three different categories. That is going to be cleaning, surfacing, and coloring. So on your screen, you see what we consider to be our print to product workflow. That's a theme that we're gonna keep saying. So from the print to the final product. So going left to right to just briefly describe what each machine does to set the stage of what post processing can offer. The first two, are going to be our bead blasting systems. This is going to be the PowerShot x or the larger older brother, the PowerShot dual performance. These are both going to offer bead blasting in terms of cleaning. So it's gonna remove that, powder from the outside of the part that David was describing, and we can also take it one step further and use a separate type of media that is going to be mechanical shot peening. So, therefore, we're gonna reduce the surface roughness, make it a more homogeneous, surface finish on the part. The larger, machine next to the smaller machine, there is our range of vapor smoothing technologies. So I'll speak a little bit more about the advantages in the next coming slides. But vapor smoothing is going to use a vaporized solvent that's gonna seal the part surface. So it's gonna mimic an injection molded part. It's gonna significantly smooth the surface and then make it, more durable against everyday wear, contaminants, things like that. And then our last step in this process is coloring. So this is our deep dye coloring system. I'll talk about more advantages here, but it is a coloring system that embeds the dye into the materials. So you get a very biocompatible and permanent means of coloring three d printed parts. Another thing I wanna touch on is I get the common question of how do I get started. I don't have the means for this capital expense. So we've heard the feedback, both HP GoEngineer and DyeMansion, and so some smaller options are coming to the market. David gave a great overview of the HP 1,200, which is going to finally get the foot in the door, pun intended, for the o and p space. So it can do the size of most of... Or some of these products. To couple with that, dimension came out with two smaller systems as well. The The first one is called the PowerShot Go. So that is going to do the same cleaning and or surfacing that I previously described. And then the next one is our VX one, which is a vapor smoothing system. So it will vapor smooth p 11, p a 12, and TPU. So all that to say in summary is that we're gonna take a part that is fully encased in powder, and we are gonna turn it into a finished device that is surfaced and clean... Or surfaced and colored and a part that your patients will love to wear. So now I'm gonna talk about the benefits of vapor smoothing. So our vapor smoothing technologies uses a vaporized solvent, which is also very biocompatible that's gonna condensate on the surface of the part and mimic an injection molded part. You can see in this video the clear benefits of vapor smoothing. The part on the left has been vapor smooth. The part on the right has not. So when we pour a contamination, in this case, water on it, you can see that the vapor smoothed one is going to repel that water and can be easily wiped off. Where the dark blue part, which has not been vapor smoothed, is going to soak up that contamination or water, which is very difficult to get out of the porous part by nature. So this is gonna protect against dust, dirt, oil. It's gonna, be more comfortable to wear against sweat contamination. And, actually, the solvents that we use inhibit bacterial growths. You know, that's not only safe, but it is cleanly to wear on the patient's skin. Another benefit of vapor smoothing is we're gonna take basically the peak of the three d printed part and micro dissolve it into the valley of the three d printed parts. We're not changing dimensional accuracy. We're making a more homogeneous surface finish or reducing that surface tension on the part. So we can oftentimes see improved elongation at break, impact resistance, and flexibility. So you can see those are the same parts printed at the same time. One has been vapor smoothed and one has not. The black part has been vapor smoothed. You can see it's much more flexible. This is also closely... More closely resemble the thermoformed materials that you already work with, which can be heat treated as well. Next topic is color. So why is color important? You've seen a variety of pictures of color devices. So, ultimately, it's customization. It is gonna create a patient and parent acceptance, something that they're proud to use. We can also use it in areas such as brand identification or color coding. However, when we start to talk about color, we need to make sure it's safe, especially for our littlest patients and our most important patients. So we need to make sure the parts are... The color is durable, biocompatible. It has color consistency as well as color fastness. So our deep dye coloring system is a chemical reaction that under temperature and pressure embeds the dye about 250 microns into the part. In contrast, where we've all started to dye three d printed parts is called pot dyeing. This This is generally boiling water and an off the shelf dye. We consider this a surface stain. So it doesn't doesn't embed into the material. It doesn't have any certifications or UV resistance. So all of the dyes from DyeMansion, first of all, have our color, fastness, and biocompatibility certifications from ISO. So it's very safe and very permanent. It also includes UV inhibitors in all of our dyes, so it's not going to fade to that purple blue from a black part when you get it into the sunlight. We do have about 250 off the shelf colors, many of them designed for MJF specifically, whether that is a starting color of light gray or dark gray. And then a a test that we like to do to show this is if we take a part that has been pot dyed, so, again, the surface stain. If we put hot water on it, you're gonna see what happens in the lower right image. That dye is gonna leach out of the parts into the water rather quickly or, in this case, onto your patient's skin or clothes. Not a good thing. If we do that same test with parts that have been deep dye colored or, again, chemically bonded to the material, that dye is permanently on the part and is not going to leach out. And from here, I am going to pass it off to a quick video from a clinical perspective from Dan DeFonseca. Hi, everyone. My name is Dan. I am the prosthetics designer at the Atlanta Clinic for Upper Limb Prosthetics, and I'm going to touch on an exemplary case of what a digital workflow process looks like in my day to day work. So today, I'll be commentating over a condensed point of view video I took of me working through such a process, and I'll be touching on each of these chronological categories starting from scanning a finished cast and then editing that scan, the design process in the main software I use, Geomagic Freeform, then build platform nesting to send a job to the printer, the printing itself, parts retrieval after a print has finished, post processing the parts, and finally assembly. Note that I am not including the casting and diagnostic socket steps in this, though we have started to print clear resin check sockets for non immediate clients So our digital process starts upon completion of a finished cast Which will then be prepared for scanning During scanning I just have a hole drilled in my desk so I can rotate the cast and hold the scanner at the same time Once I have a good scan I'll quickly edit out any artifacts or unwanted geometry From scanning, I move directly into free form and start by recruiting from the library of assets I made to make definitive processes. That could be different types of risks, electrodes, batteries, controllers, hardware, and so on. It is here where I'll all get everything aligned perfectly and check for component spacing. The device I'm using here is a haptic pen by 3D Systems. And it's a device that allows you to feel any three d model you're working with. You can feel the texture of a surface, the density, viscosity, friction as if the model was real and in front of you. With that, there are various tools at your disposable for manipulating and creating structures. Beyond basic construction, you can make some fairly complex volumes and shapes For this prosthesis, I ended up making several unique cosmetic covers and one very flashy and futuristic one So this is a time lapse of a print done on our HP580 On this machine, I have printed as many as eight trans radio prostheses overnight in ten hours and fully colored and finished by morning. Once a print finishes, it starts cooling the parts and reclaiming the support powder in preparation of extraction by morning. Here, I'm just doing some wiring for the more complex cosmetic cover, which will be at the end of this video. Now this is the extraction process where unlike most printers, the support material is the unused powder itself, which just gets reclaimed and recycled for future prints. At this point, you manually have to remove the majority of the powder off the parts. After reclaiming, the printer will get cleaned and prepared for the next print. The parts will then get glass bead blasted in a blasting cabinet. This one which has a certain level of automation to it. And after that, the parts are all cleaned up, and absolutely necessary step will be vapor smoothing. This will anneal the parts, make them even stronger, seal and smooth the surfaces, as well as make the colors pop with a much higher level of vibrancy. This is also so very important for hygienic reasons and reducing friction on sleeves and overall weatherproofing. The last step is just assembly. In this case, that includes a basic Myo setup with electrodes, batteries, wrist, charge port, and fasteners. The socket of this Myo was also made in TPU just for a bit of extra added comfort and compliance. Normally, this is where the device would be finished. But like I said, I went a bit further with a range of cosmetic covers. These ones with the rhinestones are wrapped over a gray part in silver and gold, and the rest are all different color patterns and topologies for a variety of different looks and textures. The idea here with all the cosmetic covers is for variety and self expression. An endless supply can easily be made by just applying an image with patterns or textures over the three d model. I ended up making nearly a dozen unique covers for this mile, and more could easily be made upon request with very little effort. Lastly, here is the ultimate cosmetic cover. This was a really fun one to make with lots of unique features and lighting, going for a futuristic cyberpunk look. There are many different ways to apply colors and textures to three d models. Unfortunately, I didn't get footage of me doing that, but I use a software called Microsoft three d Builder for the most part. There is a whole range of softwares that this can be achieved on, but ultimately, you'll need to render a three d file such as a three m f or POI for the builder software to intake and process into a file for the printer to execute on. And at this point, the finished device is ready to be dispensed to the client with all its various cosmetic looks ready for modeling photoshoots and day to day activities. Perfect. Thanks to Dan for sending this video. Unfortunately, he couldn't join us for the live version of the webinar, but that was a great video. And with that, comes the end of our presentation for today. I would like to thank all of our presenters for today. They're gonna join me in a stage in a few minutes and then, for question and answer. So we're gonna give a few minutes. If you have any question and answer, you can pop them in the q and a section. Or if you want to directly connect with us, you can send us an email with our email being here on screen. I'm gonna leave it here for a few seconds so that we get a chance to go over a few questions in the chat. Question number one, I think that goes to Emilie. Someone has asked, can they create custom dye colors? Absolutely. Yes. Although we do have over 250 colors off the shelf, including raw and Pantone colors, There is an option to custom color development. So you've got... You have a brand color or a patient's favorite color, we can absolutely do that. Thank you. Second question. Someone has asked, do they need to download any official software to use DyeMansion? No. It just runs in your Internet browser. I think, you know, the recommended one to use and the one that I use is Chrome. It runs great in that, and you don't have to download anything. The only thing that you'll end up downloading are the files that you create that you'll end up sending to your printer. Thank you, Richard. Someone has asked, how does MJF differ from an FDM printing? Maybe David could take that. Yeah. I'll take that. So, there's a few factors there. One is gonna be isotropic strength. So filament printer, majority of the strength is in like the x and y and then like layer to layer adhesion is considerably weaker. That's why we don't see a lot of filament printing devices just because there's torquing and forces that aren't like directly stable to x and y only. So there's that. The other area is just, throughput. So filament printing versus, like, our process. I think I did analysis when I first joined, and I think for 10 filament printers of what they could do within a year, one of our systems could do in, like, a week or two. So just the speed output is considerably different. So those are, I think, the two main factors. The other one is you don't have to deal with support material. And if you ever dealt with support material, that is the biggest relief ever. Like, that was my most exciting thing joining HP's. I don't have to deal with chipping away or shimming off support. So all those three things, so that's the biggest factor. I... As I mentioned, like, filament printers still have a good spot. Like, our system's not good for printing one part or prototyping just that. Like, we're batching it altogether, so there's still a good spot for it. But end use devices, it does have a few limitations versus MJF. Perfect. That's awesome. Thank you, David Johnson, for that answer. One question is, are there any privacy issues for patient or confidentiality when it comes to this? No. It's a secure website, but the other thing is is that you're not really uploading any patient identification data, that could be traced back. I don't really think, but it's. not really a concern. And on the printer side, we don't see any models ever. We just see, like, data points. So we we can see that, like, how many things are printed. We don't actually see any part geometries or data files in that sense either. Okay. It's the same with post, processing. Greg. We don't see anything. Great. One other general question that came into the q and a. Someone has asked, how can they get us started in three d printing and maybe in their digital journey? Go to GoEngineer and check out the resources that are available on our website. It would be a awesome thing to do. If you go to our YouTube channel in particular, I think it's one of the best resources for SOLIDWORKS and three d printing that there is. Great. Just to add to that, also, is, look up your local service providers. There is a network of service providers around North America, actually worldwide, who specialize in this. So they can ask... Often help with the design if you're trying to get more comfortable with that, but then they, do the three d printing and post processing. So there's quite a few in Canada, quite a few in North America, and that would make sense to send one part to instead of having to buy an entire ecosystem to do one offs. That's generally where people start. Other than that is the smaller technologies that are coming out now, such as the MJF 1,200 and the smaller post processing. You're gonna be under about a 115,000 US dollars to bring that entire thing in house, so it's a lot less than the larger capital equipment is as well. And to piggyback on what she just said, like, utilizing a service bureau to try different technologies and different, materials before committing to the capital expenditure, is awesome. And, that's another area where you can leverage GoEngineer because we have all of this technology in us. Perfect. Another one, maybe Emilie could take that. It says, how do OMP companies approach matching colors, for their devices based on customer demand and preferences? Absolutely. There's trends for colors with an O and P for pediatrics, the obvious blue and pink. And then for adults, generally skin tone or black, sometimes the green, the blues, things like that. So of the 250 colors, you can definitely... You'll want to narrow it down. But as far as our process, the DyeMansion DM 60 is a batch based system. So we can accommodate small, medium, large, and extra large batches of parts. So in the most simplest terms, it's a pressure cooker mixed with a Keurig. So you're gonna select that Keurig pod that says the color and says the batch size of the parts, and then it takes about two and a half hours for the entire batch. So with that being said, you could do five colors in a day, but you definitely wanna prioritize cost per part and making sure you're not just having one part in that. It's great. Thank you for answering that. Another question in the chat is what are type of devices that you can design on leo shape, Richard? Yeah. The three primary core modules that are available publicly right now are the LEO insole, the AFO module, and then the spinal module. But I'll say this, that there are other modules that are available that you can easily demo. They're just not necessarily ready for prime time. So there's one that is very similar in operation to the AFO module that is for, upper limbs. And then I'll also just as a as a bonus thing, say that, you know, that application that Dan was using in his video, GeoMagic FreeForm along with, like, a haptic device is another thing that is available through GoEngineer. And, it's phenomenal for covering all of the other types of devices that you want to make. And it's also really great for like... Let's say that for some reason you want to customize the device that did make in in LeoShape, it's a it's a powerful tool to use in conjunction. Like those two things together cover essentially all of your bases. Yeah. I think you asked her the other question I was about to ask you. Someone had asked, Oh. what are the other devices that are not covered in LeoShape? Yeah. Yeah. Definitely, you know, anything that you can imagine in terms of device can be covered in free form. And, we'll definitely have to do another webinar on that application because it by itself is is absolutely incredible. That's great. Thank you, Richard. Another question. Maybe I could take that. How does GoEngineer work? Do you sell the services or the technologies? Well, that's a great question. So GoEngineer is your digital manufacturing partner. So we provide you with the technologies, with the training, and with the services as well as having access to all those technologies. So the easiest one is you acquire the technologies, we help you get set up, how to use it. The other one is that GoEngineer also provides printing services as well as post processing services as well. So if you wanna do it as a service, we could help you with that, or if you wanna have access to that capital, we could also help you as well. Especially when we have great engineers on our team such as Richard, Hardik, as well as our partner like David and Emilie, we are well suited to answer any question or any request that may come our way. So anything that comes to your mind that you may need help and assistance with, we're more than happy to sit down with you and have a conversation and see how we can support you in those opportunities. Richard, guys, did I miss anything on that? No. That sounds great. Perfect. So question, I think, for David. Which material can mostly be used in OMP on MJF? Can you can you give more specific, like, 60% p a 12, 30% TPU, etcetera? Got it. Like, I'm assuming that means, like, total usage Yeah. across the two. Yeah. So, O and P is a little trickier, but, like, in general... So, like, our global material usage, like, our normal PA 12 covers about 80% of all our materials. So, like, that's definitely the most utilized one. It's a little interesting when it gets into o and p. So, like, from an engineering material science point, like PA 11 is probably the better choice for the type of device forces that go through it. The challenge is it's a little bit more expensive than PA 12. So, there's a balance of like the location of how they do reimbursement rates versus the actual device and, you know, material selection. We do see that with, like, Europe uses more p a 11 than p a 12, and then the North America typically uses p a 12 over p 11 because of the pricing difference. As far as for, like, TPU versus p 12, I would think it's, you know, p 12 is 80%. I would think it's probably somewhere there. Like, 80% is, like, a function of PA 12. It's like we have our PA 12, our our light grade that's more used for dyeing. And then the TPU, I'd say, is probably, like, 10 to 15%. One of my customers only uses TPU for their devices initially. That's all they do. They they just started doing a rigid material, and they're one of the top, like, global users of TPU now. So it definitely can be utilized at a high rate. I think just because most will start with p a 12, and then they'll bring on a separate material because you have to have, like, a isolated, processing station and building this because you have two different powders. We can't, like, mix them together to print all at once. So normally someone will start with one material and then we'll bring on a second one. And that's usually why we see TPU drop because the rigid material is usually the the first one that they'll start with and then say, hey. We wanna do inners or we wanna do a new device if you're a combination. They'll bring on that second set of materials to, like, offer more for their devices for it. Yeah. Perfect. Great question. Thanks so much. Thanks. Great answer as well, David. Appreciate you. thank you for your time and, appreciate you joining us for this webinar today. And we'll love to hear from you. If you have any questions or any, feedback, we'd love to hear from you. So thanks again for joining us for this webinar today, and we hope to see you soon again. Thanks. Simpson. Thank.
