Dear Peter and Stephanie. Thanks for many good shows! Could you make an 'differint infill-geometry overview with mechanic proporties and aims' like strength, cost reduction, time reduction, impossible structures and more
🔴Update: At this time, Curiteva has FDA clearance for the cervical and lower lumbar implants. These include the following: Cervical PLIF - Posterior Lumbar Interbody Fusion TLIF - Transforaminal Lumbar Interbody Fusion ALIF - Anterior Lumbar Interbody Fusion OLIF - Oblique Lateral Interbody Fusion DLIF - Direct Lateral Interbody Fusion
I assume that the pulling forces applied during deposition gave them a hard time with adhesion. I guess that's why we see two rafts under the part. Also some FDM parts can deform so badly during printing that they rip out a piece of the glass bed. Here we see a totally different bed material. But since it's all proprietary, they probably won't want to discuss it too much.
Every time I see the clip of the Carpenter Additive blue containers with all the metals, I remember that a random person sees anonymous drums but I realise that there are literally millions of dollars of value there. I've handled inconspicuous bags of pharmaceuticals that cost hundreds of thousands of euros each and I couldn't figure out whether it is good to have the price in mind or not.
Thanks for watching. We have an extended answer for you... Please note that anyone reading this for medical advice should consult with their doctor for more information on this topic. That said, the short answer is: Yes. More from the Curiteva team on this: "The use of cotton and evans wedges is a surgical procedure that helps create an arch in the foot. It is commonly performed to help correct the condition of pes planus (commonly called flat foot or fallen arch). The surgeon performs a cotton osteotomy by modifying the medial cuneiform and creating a slit to accommodate a wedge which changes the shape of your foot and returning it to a more normal appearance." At this time, Curiteva's wedges are proof-of-concept and have not completed the FDA approval process.
Here is what the Curiteva team says in reply to your question: PEEK is a path dependent polymer. The thermal history is important during the pulling of the strands (FSD). Strained induced crystallinity is created during this process. The ideal temperature conditions need to occur during the deposition, while the chains are aligned and toughened. Simply post annealing will only realign the polymer chains. The strain induced crystallinity will be lost. Thanks for watching!

Short answer is yes, but you'd still end 😢up with a vastly different end result. Their unique Fused Strand Deposition process differs from traditional FDM or FFF printing of PEEK filament that is printed in the amorphous form accounting for the shrinkage and warping that will occur after baking to convert the PEEK from its amorphous state to the crystaline state. In this more traditional post processed way of processing PEEK, the crystal structure is somewhat random and depends among other variables upon the unique shape of each part. In the case of FSM, as each strand is filament is laid down, they place it under specific strain and heat it until its crystaline structure is locked in preserving the internal stress / strain they desire in each individual strand of filament as the part is built. Think of big building projects that use pretensioned wires, not only does this allow them to produce a part where the crystaline structure is very tightly controlled and can vary in direction and grain size through out the part, it also allows them through detailed computer models to control and optimise the part given where the bulk of the stress is likely to be applied allowing for a part that is overall much stronger and is able to more effectively distribute stress and forces throughout the part which decreases failures and allows the part to more closely behave like the piece of bone it has ultimately replaced.
This is why I hate capitalism, this is such a cool discovery, but instead of releasing it to the public they have to patent it and guard it so competitors don't get a leg up and they can profit. How cool would it be if they just released the slicer they use to do fsm with peek. Imagine how many other industries and hobbyists would benefit

@@luisgodoy8483 why don't you realize that when I do use my imagination and produce things they're eaten alive by capitalism. Everything is filtered through money and it degrades and worsens the result.

I want to get a 3d printed spine implant so bad!!
🔴Update: At this time, Curiteva has FDA clearance for the cervical and lower lumbar implants.
These include the following:

DLIF - Direct Lateral Interbody Fusion

what is the best 3d printer currently
nice. ty
You should turn your "final summary" bits into a short
That's not a bad idea!
And it seems the short already has more views than the original. I guess that's why everyone makes shorts.
@@raulkaap the shorts pay less though, but if they're good, it can get more people interested in your content
@@pauljones9150 Worth a shot, especially since they already have the footage. They'll work it out.
Thank you 🙏🤲 much greatful

What about vertebrae disks? How far is research on this advancing?
Those videos from one of those guests didn't seem very nature, too monotone.
Love the cool stuff you show
🎉
Would this be applied in flat feet

Couldn't PEEK be heat treated after the fact, to achieve the desired properties?

Well, what if you change your hatred and make a good investment, develop everything your imagination can produce and give it to the world?
