PEKK Vs. PEEK for 3D Printing | The Cool Parts Show Bonus

PEKK (poly ether ketone ketone) and PEEK (poly ether ether ketone) are both high-performance, semicrystalline polymers that offer good strength, chemical resistance and high use temperatures. Both materials are used for medical implants, among other applications, in part because they offer stiffness comparable to human bone. But the same crystallinity that imparts many desirable qualities to these polymers also makes them challenging to 3D print. We recently featured PEKK suture anchors made through selective laser sintering (SLS) by Oxford Performance Materials, and PEEK cervical spine implants made through fused strand deposition (FSD) by Curiteva on The Cool Parts Show. In this bonus episode, we reconnect with our experts for their perspective on additive manufacturing with these materials.

Great. Now all we need are episodes on PEEKK and PEKEKK

[@gtgeorge1814]

Great EP, you really PEEKed my interest.

[@saml7610]

Great explanation of semi crystalline vs. amorphous polymers. We took A LOT longer to cover the same info in my chemistry courses kn college. This was a much more concise - and more understandable to the layman - way of explaining it. Another great video, you guys have such good production value, it's perplexing you don't have more subscribers!

Thank you outstanding work like usual keep it up 📈🆙👏👏✨✨🙌🙌🔥🔥

They will utilize strength And degradation rate as different values for these implants.

[@wilsonkailunwong2286]

just a bit of comment. solidification and crystallization are two very different concepts. 1:32 …. this is very wrong.

[@wilsonkailunwong2286]

p.s. phd in materials. been doing nano ceramic reinforced peek since 2006.
