CNC has traditionally been the process and technology of choice for creating specialized medical implants. The reason 3D printing is not being used for these types of special pieces is due to the materials not having been approved by the FDA. Additive manufacturing processes can fundamentally change the physical properties of the metal or plastic substrates that it uses, thus making them a tricky choice for implants. However 3D printing may be changing that with a new patent by Oxford Performance Materials (OPM) for its PEKK (polyether ketone ketone) polymer.
