 Capstone project and first one was done in 2015. The altar was on the end of it and he's just started from the design of this short intramedulary nail. Next year we have a Vahak who designed the long intramedulary nail and Gagik who did some business stuff, some preliminary ways to commercialize the nail. And now this current year Levon is engaged in the project. A little bit from different point of view he conducts, he should conduct finite element analysis and prepare the methodology for cadaveric contest. Of course when we decided to manufacture and fabricate prototypes then we had to redesign the models created by the students because they should satisfy all the production application requirements. And so this is done and the drawings are prepared to be fabricated for publication and then the important issue here is what the design should be for the publication, what the specific requirements should be. And here at this point Ed joined us, joined our team and his experience, his expertise in this field helped us very much and I just want to bond him to continue this talk with regard to this aspect, design for manufacture aspect. Great. Great, thank you everyone. Thank you for bringing me on with this project. It's very meaningful for me. I'll get right to it. So design for manufacture. This is a very broad topic that we could spend months and months discussing but there are a few key elements here that we need to address. Right. So you heard that this device seems to be effective. That's the first and foremost, most important part of it. But as you also heard, these devices are extremely expensive. Surveys are expensive. Tools are expensive. Just takes a lot of recovery time. I have a lot of time cost at all. Sorry, just let me know when I should change the slide. Okay. Yep. Thank you. So, you know, it's very important for this device and system to be as cost effective as possible. And cost comes from a number of different places. One element of design for manufacture. So I'll talk about a few of those elements here. And those being materials, features of your components, and manufacturing processes require the fabric of these components. So they, you know, they look like separate items. But what you'll see in here is that they're really all interdependent. They drive elements to each other. They all drag costs. So, as you heard, you know, there's one of the industry leaders simply, they have a very complex system. And what we thought of is, you know, let's take a look at design. Let's see where we can improve. This is a place where we can improve our cost, our simplicity. So, you know, I really came to this project at the right time. There was a step developed, and now you'd be optimized for any factoring, technical drawings created. So, again, you know, trying to make an effective product that keeps costs in mind. Next slide, please. So, the industry leader makes their effects at the factoring. And, you know, material alone is a little more expensive than others. So, what we thought of is, hey, you know, maybe we can make this out of stainless steel. It's not ideal. It's not optimal. But, you know, we think it's a material that can still allow us to have an effective product that's going to help a lot of people make a difference. You know, although another element of this is, you know, you're trying to keep any factoring both to our media, both to our media as possible. And if we can't find these materials for factoring, well, you know, we're not really meeting the goals we're trying to meet. So, keeping in mind, how we're getting these materials, the cost of these materials, you know, plays an impact on it. And, you know, although we were able to create a sub-titanium, well, we've made some prototypes, which you'll see in a little bit. You know, we're trying to see, we're trying to go down the path of perhaps developing the device at stainless steel. Now, next, what we'll look at is component features. You know, are there any that we can leave out? Anything we can simplify? You saw all the different tools in that animation. Now, are there any that we don't need? Can we implement the value added features of those components into the rest of our system without needing additional parts and tools? You know, every additional tool is more money. The simpler we can keep this, the lower we'll keep our costs from a device perspective, the lower we'll keep the costs. We'll cost it at all. You know, really all of them are connected. So, one feature we identified on the Simpy's nail is a tool that goes down the center of the complaints. You know, it's a machining step that we are hoping to avoid. You know, it's a long feature. And to machine this, you know, this part's machined up a late, you need an equally long and narrow tool. You know, that when you have a tool that's so small and long, it's so narrow and long, it blinds itself to premature tool wear, you know, deflection engineering machining. So, you might not be able to achieve that feature in its surface characteristics because of the complexity of it. When you go through the steps of design, you also want to think about your tolerances. When you're dimensioning these parts, you know, these aren't perfect dimensions. You're not going to have a 100 millimeter line in place every single time you need to allow for some flexibility in the machining process. So, you have to think about what can I allow as my dimensional tolerances for machining? Is it plus or minus one millimeter? Is it plus or minus a quarter millimeter? Plus or minus 15 microns? And a lot of this is dependent on feature size. So, you have this, you know, 100 millimeter long nail. You know, what's a reasonable tolerance for its length? You know, probably plus or minus four millimeter is fine. You don't even go as tight as plus or minus 15 microns. You know, the tighter your tolerances are, the longer it's going to take the machine, a lot more kick, a lot more time and efforts and then you need to go into creating your part to those tolerances. The more time that is required, the more expensive your part becomes, the longer it has to stay on the machine. So, when you think, not yet. So, when you go to, can you back up a little bit, please? Can you go back? You also think about the machine process required based on the features you have. Can you limit your part to be in one piece of the fitting? You saw these handles. You know, those get nailed. The nail gets trimmed on the lathe. The nail also has a thing to it that gets applied after application. It's hardly down the shaft. But, you know, this is unavoidable. There's no way to make this on a lathe. I'm sorry, apply the pen on a lathe. So it's a separate process of fine. You know, are there ways, you know, like you're going to report me, like are the client's tolerances easier materials for machining or separate features? You know, this isn't an exhaustive list. It's, you know, a few features that we identified as, you know, able for us to simplify. So, you know, that's one of the things to think about that's, you know, not necessarily related to design for any factor, but it has its related concepts set up time for your CNC machines. You know, when you have, you know, depending on the lot sizes you're producing, the size of your lathe is going to correlate to your part cost. So, you know, let's say you want to make one part. There's a lot of step-by-step involved to make sure the machine is up and running. Make sure you have the correct tools loaded. Make sure your, you know, probe rate is set up correctly to machine the part. So that first part is always the most expensive part that comes off the machine. You know, that first part may cost you $1,000. But if you're going to make 20 parts, you know, the total cost may come to $1,500. That first part is run. The machine can keep going on its own. It doesn't need someone there to watch it. So just, you know, think about that. Keep that in mind when, you know, when designing parts, when looking for, you know, people all get to see that, you know, the potential decrease in cost within more number of parts you're going to fabricate. The next one is about hand-in-hand. There's a lot of creativity in designing. We talked about the machine process, but it doesn't, you know, it doesn't really stop there, everything by inspection. Yeah, you can, you can modern parts with very complex features and dimensions. But will your quality control team have a method to verify this? You know, once parts are machined according to your spec by an outside machine shop, you know, immediately...
