Abstract
Prosthetic bone implants are fabricated to approximately replicate a patient's original bone. Medical computer aided imaging techniques are applied to generate a data base representing the size and shape of the original bone in a three dimensional coordinate system. The implantable replica is fabricated using the data base and free form manufacturing to sequentially solidify adjoining, cross-sectional intervals of a fluid material. Appropriate fluid materials include ceramic particles which may be selectively bonded by sintering or bonding with a polymer, and a monomer which is polymerized at selected regions by an incident laser beam.
