Here's 50g of it on Amazon for $16: https://www.amazon.com/Myoc-Keratin-Powder-Conditioner-Produ...
And you can get it from chemical manufacturers in purer forms for much more expensive but that's true for any high grade chemical.
In fact, if we type your question into Google we find this 2019 article that even references a 2015 article about attempts to do exactly that: https://www.vox.com/down-to-earth/22723289/3d-printed-rhino-...
I highly suggest googling solutions that you think are rather obvious. It can often lead to surprising results as things can interestingly become complex. And at the worst case, you find that your idea works and you can throw in a citation to give your proposition more weight. Seems like a win win to me and at very little cost in time.
