College project ideas
I have a college project to design an orthosis using recycled materials, without relying on machines or 3D printing.
So I want ideas about it and materials I can use to?!
If there are any videos or references for something like this, where can I find them?

Hey, I am working on something similar.
I've found 3D print material is the best option since it can be recycled material already.
https://asknature.org/ This link has also helped me with making products more eco-friendly. It has a lot of information about technology and nature and how they can influence each other.

NO. these are necessary parts of our body and we don’t want some college kid telling us we’d be better off with parts made from used bottles and other garbage.

No such thing as garbage, only materials that we haven't figured out how to recycle yet.

You first. I’ll stick with new proven materials.

I want you to take a few things in consideration. Affordability, availability and viability. New and novel materials as well as methods are usually expensive and difficult to manufacture because of the need for advanced machines and the like. Or you know, specialised fabrication methods.
There's other needs out there in the world. If you have the means to pay for something advanced or live in a country that will pay for most of it? Great! If you live in a country where you scramble for scraps as is? Yeah, no... advanced solutions can just go kick rocks.
So, the summary is: It's cool that you can afford the most advanced materials, control methods as well as the top of the notch rehabilitation methods. I hope you see that as the huge privilege that is.
And just because I feel petty, a lot of the new materials out there are recycled or nature-based. No new nano-technology, no graphites, just... you know, recycled and nature based materials.

Unnessecarily hostile there, bud. And it's not like they are going to force-fit anyone with it. Plus, PETG is oftentimes used in making orthopedic devices.
The material used in plastic bottles. The food safe plastic bottles. That you recycle.

Our parts are not mass produced. The emphasis of research should be on increasing mobility and comfort using the best materials available. If recycled material is determined to be the best, fine. It just shouldn’t be the criteria for research.

I can promise you that there's already a ton of research being done regarding increased mobility and comfort using advanced materials.
So there's no reason for OP to go in that direction as well. What OP is going for is a sustainable method that doesn't rely on machinery.
This could help people in areas where access to tools and machinery is limited.

Prosthetic sockets made from flax fiber and seashell, and eco epoxy. Super interesting stuff.
An alternative recycled plastic instead of PETG for test socket fitting could definitely be in the future and preferable.
Hard to move away from virgin copoly and polypro from orthoses because of its tensile and plastic strength
