Machining a Next-Gen Spinal Implant: My PhD in 9 minutes

The video discusses degenerative disc disease and a PhD project aimed at creating a novel artificial disc replacement. It covers the machining of small pins, the design process inspired by watchmaking, and the assembly of components using staking. The video also explores the use of electron microscopy for examining manufacturing quality and concludes with testing the implant's performance. The results are promising, but further work is needed to bring the implant to market.
