Improving Medical Implants with 3D Printed PEEK | The Cool Parts Show #63

Polyether ether ketone (PEEK) is used in medical implants for its modulus akin to human bone as well as its radiolucence, giving physicians a clear view of a healing injury via X-ray. Implants made from this material until now have mostly been molded or machined, in part because of the challenges of 3D printing PEEK. The large delta between the material’s glass transition and melting temperatures makes the polymer tricky to apply with standard fused filament fabrication (FFF). Curiteva instead uses a novel 3D printing method called fused strand deposition (FSD), which does not fully melt the filament and actually pulls the material along as it is being deposited. The company has achieved FDA approval and is now in production for its first 3D printed PEEK implant, the cervical spine cage featured in this episode.
