At work, we have multiple projects going on simultaneously in R&D to enhance some of our product lines. One of the projects involved mixing in a different material to reduce the overall weight of the implant. Another project involved aimed at making the implant more smooth by altering the implant geometry slightly. It turns out making that slight geometric modification reduced the overall weight of the implant. So now we’re looking into combining both projects and making prototypes then testing the feasibility. I can’t go into too much details because it’s proprietary information, but hopefully the general description I gave makes sense!
