 We'd like to be able to trust them, but this is your part, this is your name on the line. So you need to confirm that what's critical to your part has actually been machined so that you can ensure print performance of your device, make sure it's effective. So at the same time, 3D printing brings a new way for us to make quick prototypes. It's a great way to evaluate pieces of the quality of its design and it's getting a part in your hand for evaluation. What's great is that, you know, it's great, maybe not so great, is that you can print geometries that you might otherwise not be able to produce in a cost-effective manner. Some features may not produce at all, but traditional machining techniques, you know, belling or turning. So be sure you think hard about the features in your design. You know, think about the tools required, the drill, the drill bit on this ember approach. Make sure you think about all of these elements when you put together the design. Next slide. So design for manufacturers is a balancing act. You want to ensure you have a robust product. I can't forget that what's on paper is not the only thing that's important. You have to make sure it's something you can manufacture. Make sure it's something your quality team is going to be able to inspect, verify those critical features and dimensions. It's a cost-effective, you know, how we made this device as, you know, as complex as it needs to be and as simple as it needs to be that we can keep costs down. And, you know, if you couldn't solve already, our new impact should be collaborating, you know, as much as possible here. You can have a design. You can have a creative concept. You can have the best concept. But if you can't make it, then you get the fact that you're enjoying the work. That's how you fix up that waste time, that waste of your time, you know, that waste of the company's time, the waste of the company's money. You know, always, always include your new factory in your design efforts. And, you know, finally make sure you're still meeting your customer's needs. You know, at the end of the day, that's what's most important. So, with that, I'm going to back over to Sarkis. He'll talk about the prototypes we've developed. And I do have to step off the line. So, thank you very much. This is great. And if you have any other questions, feel free to reach out. Sarkis has the mic. Sarkis, make sure. Thank you, Ed. Thank you very much. A lot of very detailed concept is presented about how to design for manufacture. Some of them we used, some of them not, because this is not mass production. This is just a production of prototypes. And we did it. We published it. We managed to fabricate a batch consisting of seven, eight prototypes. Complete kit, including the accessories for insertion, surgical accessories for insertion. I just want to name some challenges that we encountered during this process. First of all, it was difficult to find a producer, but because here the production components are afraid of dealing with this material, titanium. They say it's difficult to machine, but I think that here corresponding appropriate tools should be used, and appropriate parameters, cutting parameters should be used that we unfortunately still don't use. And finally, we found Hycola, its company, manufacturing company that agreed to manufacture these prototypes. Then it was difficult to find, not difficult, but impossible to find the material here, because this is a special medical material, grade five titanium, it is called. And we here applied to our very good graduate who works in Tehran, Sevan Ter Sargsyan, and he managed to send this material for us. I should say that these parts that remain within the body are from titanium, and these parts that are used during the surgery are from stainless steel. No problem for this, but the material is found that way. And the difficulty was to drill these deep holes that are in this part, and we had to order a special tooling from England to drill these holes. So these were difficulties, but eventually the prototypes were created, and they managed to finish this. Today, before Levon took them to Harvard for tests, and now Levon will just describe his experience in Harvard. Hello again, and thank you for the wonderful presentations. So what happened after the fabrication on the edge of the prototypes, is that I took the prototypes to U.S., to Harvard Medical School, where we have the Nazarian lab at the State of Israel at Levon's Medical Center. First of all, it was a wonderful experience for me to go to this kind of large community of scholars, to the working lab, because we have the ethnic prototyping lab here, the newborn lab in Armenia at the UAE, and I could compare it to the already working Nazarian lab at Harvard. So first of all, I will tell you about our goals, why I went to Harvard, and what was our plan. I took a bunch of the prototypes to the lab for testing. First of all, we were thinking about satisfying the ASTM requirements. ASTM stands for American Society of Testing and Materials. So what they have is a 1264 guideline for the long intramedulin nails, but they don't have a guideline for the short nails. So we tried to use the guideline for the long nails and try to adapt it to our case. There were some problems because you cannot do, for example, three-point or four-point band testing on these kind of small nails physically, and we couldn't conduct the tests at the lab. So we decided to change our direction and try to do a finite elemental analysis instead of a real life test. So about the tests, there are two kind of tests that we wanted to make. The first one is just one-time test for load testing. It's basically the maximum load the implant can take. We could do it with a hydraulic press by just having a constant displacement rate and trying to see the maximum load that the implant will take before breaking. And the second type of testing is the fatigue analysis, which is trying to see how much load the implant can take after, let's say, 250,000 cycles. How do we take this number? It starts from mid and mid-air. We calculated the number of 250,000 cycles from the 12 peak healing period multiplied with seven days times 6,000 steps per day for each leg. So we get something around 250,000. And also during the working process, each leg, a femoral bone, takes a lot of two to three times of your body weight. So we are going to see if our implant takes three times the average body weight of a statistical Armenian or the US citizen. So we decided to compare our implant with the Sintas implant that they already have in the market because if you want to get an FDA approval, which is the Food and Drug Association approval, it will be easier for you to compare your product with already existing products and to show that yours is not worse than the already existing product in the market. So it's a versus battle for the AUA and Sintas models. And we will also try to do mechanical tests for the cadaveric bones. What the cadaveric bone is, it's the bone of a dead person that you take. There are many companies that you can purchase dead person's leg or, for example, a femoral bone. But it appears that those legs are very expensive. If you want to purchase, for example, a dead person's leg for the femoral bone testing, you would need around $800 to $100 for one sample. And it is essential for us to minimize the quantity of the bones used so that we can keep low the cost of the testing. So it's basically minimizing the number of tests for trying to understand the maximum load an input can take for 250,000 cycles. All of this together is going to be my capstone project that I'm going to present in the early May, hopefully. And also about the Nazarian Lab. As I said, it was very interesting for me to see how the Nazarian Lab works because we have the newborn epic lab here and trying to prepare them was really interesting and a mind-changing experience. First of all, it was at the infrastructure that they had, the administrative team that was working, trying to manage the projects and stay on the go. They were trying to make these decisions as flexible as possible and trying to fit the research groups. What effect do the research groups, as Anna told us, is trying to come up with teams from multiple disciplines and even in their rooms, you could see one electrical engineer, one biomedical engineer and one mathematician sitting in the same room trying to come up with ideas and trying to come up with solutions for the problems. And one important thing is that we are not that we are not.
