POROUS METAL STRUCTURES MADE FROM POLYMER PREFORMS

摘要

The present disclosure relates to porous orthopedic implants made from polymer preforms and a method of manufacturing the same. A polymer material may be formed into a preform, such as by an injection molding process or an additive manufacturing process. In an exemplary embodiment, the overall shape and the porous framework of the preform is predetermined to be substantially the same as the overall shape and the porous framework of the final orthopedic implant. Then, the preform may be pyrolyzed and coated with metal to form the final orthopedic implant.
