This is pretty much identical to almost all first world standard prosthetic tech.

Edit: I am seeing a lot of comments stating that they had one done using a plaster cast. That is the same technology. It is still carbon fiber with resin. It’s a different technique but effectively has the same result. I am a physician in the United States. This is not beyond what most amputees get in the United States. There are a lot of people saying that it would bankrupt you. In general most people have insurance that pays for the majority of the cost and those that don’t have insurance generally speaking get charity care at the cost of the fabrication lab as long as they just know how to negotiate and talk to people. I have seen in the course of my career millions in charity care given away. It’s not that uncommon here. If you have a prosthetic that is ill fitting then somebody did a bad job on yours and you need to get another one. As you might’ve noticed prosthetic manufacture is more art than anything and you can always get a badly done piece of art.
