More Affordable Surgical Devices 3D Printed from PEKK: The Cool Parts Show #60

[@scottdefelice9518]

Hi All - One little correction PEEK polymer does have a biofilm. PEKK does not have biofilm because of its unique chemistry attracts selective proteins that inhibit bacteria colonization.

[@AdditiveManufacturing]

More from Scott on PEKK: "There are lots of uses of PEKK. We do have two coatings technologies - both conventional powder coating and aqueous PEKK coating. Powder coating materials are powders that are coating using electrostatic process. The aqueous system is provided as a true water based solution. You just dip/spray and bake to around 330C and out end up with around 350nm of pure PEKK on the substrate. All forms of PEKK have the same antibacterial property though they do not elute, bugs just don’t have hospitable environment."

i watch you for a year now :) i like that your channel is growing. You are making a remarkable material with up-to-date ideas nicely composed. And i am todly in love with Stephanie - i like her rings :)

This is a Spectacular Product! Let's get rid of old implants!

Did somebody mention implants? www.additivemanufacturing.media/hashtag/implants

I love this show to bits. These inovations make me so exited for the near future everytime I see 1 covered in the show!

[@raulkaap]

Fun fact: "pekk" means "lard" or "body fat" in Estonian. Thank you for your attention.

Will this PEKK can be used in Dental implants? That will be another life changer.

[@scottdefelice9518]

PEKK is extensively used in dental at this time. We supply stock shapes that are subtractively machined into All on 4 and abutments. We have done studies looking at the viability of OsteoFab 3D printed PEKK dental All on 4 implants and the properies are suitable.

I'll check out the back catalogue of videos now. I delayed as I was worried about getting jntk something and it not doing well. Bad choice I see now, love this show. So very informative and interesting. Thanks for making these and sharing with everyone

Maybe the material's surface is damaging to bacteria the way abestos damages the body? Would love to see the anchors put through an electron microscope.

[@scottdefelice9518]

Actually the mechanism is a little more complex. The polymer has a surface energy that attracts the bodies natural proteins to the surface that prohibit bacterial colinization.

@@scottdefelice9518 So is PEKK the future material of implants then such as artificial hearts or joints?

[@scottdefelice9518]

@@jmd1743 The material is very bone like mechanically so we specialize on replacing damaged or cancerous bones in cranial, spine and extrmeity. Not a soft tissue replacement material.

[@jmd1743]

@@scottdefelice9518 Sounds like you're onto something, such as what is to lab grown bones is to lab grown organs. I wonder if one could 3d print spinal cartilage, and then have everyone change out their spine cartilage at a certain age like how colonoscopies are done or how you change you car's timing belt once every so number of miles.

@@jmd1743 "if it ain't broke, don't fix it", you do not want to go changing out parts of the human body just due to age. If people have a legitimate need for implants or joint replacements then go ahead but most surgeries, especially surgeries involving implants, the results are not as good as the natural body and they have a long recovery time. The spine is incredibly complex and a single mistake could lead to paralysis or death. For a lot of conditions now, including autoimmune conditions and physical or sports injuries they are trying to move away from surgery where possible as the results are not that great. Surgery is often only used as a last resort where there are no other viable options. One major thing you are missing is that unlike cars human bodies can heal, yes they can still wear out over time, but they can heal. It would likely be far better to just find a way of keeping the natural spine operational for longer or find a way to help it heal itself rather than just swapping it out.

You need to work on the colorspace in edit. Skin looks pale and even green.

I don't think people realize what this means for medicine that bacteria don't attach in congregations yet the body accepts it. Even gold has biofilm on it. Everything does. Well.. Apparently not everything. I've known several people with loose pins. Both had a crushed arm and a bunch of hardware for elbows and forearms. Is it only surface mounts that get removed? They both still had their stuff years later.. I guess I should educate myself on the subject now.

[@conorstewart2214]

I know this is late but they typically only remove pins if they are causing a problem, at least here in the UK. I broke my elbow and had to get the tip pinned back on, they only removed the pins because I didn't have a full range of motion in my elbow. They typically prioritise reducing surgeries over removing pins.
