I am currently working on parts for a custom prosthesis.
My main concern at the moment is to find biocompatible materials that can be 3D printed from a UP or a Reprap. The piece would need to be in contact with the skin for extended periods of time, probably around 17 hours a day on average.
The main concerns I have are:
- Skin reactions caused by prolonged contact
- Skin reactions and bruising caused by friction
- Degradation of the materials due to prolonged exposure to skin secretions and sweat
- Risks of toxicity in the compounds generated by the aforementioned material degradation
Which materials can you recommend?
Any extensive data (from testing) would be greatly appreciated.
