Commercial Laser Sintering giant EOS has been focusing on the medical market recently, using their SLS expertise to produce a variety of solutions.
EOS uses several plastic approaches, including laser-sintered nylon for "disposable, customized operating devices such as drill guides for knee and hip replacements". They're also developing "PEEK HP3", which is a "a high-temperature, high-performance thermoplastic" that is biocompatible and sterilizable.
EOS also produces direct metal laser sintering to create such items as:
- Stainless-steel prototypes for customized spinal surgical instruments
- Cobalt chrome replacement knee joint prototypes, and end-product dental copings and bridges
- Titanium dental implants with porous surfaces that promote osteointegration
