SYSTEM AND METHOD FOR PRODUCING A THREE-DIMENSIONAL BODY COMPRISING BONE OR TISSUE-COMPATIBLE MATERIAL
First Claim
1. A system useful in producing a three-dimensional body comprising bone-compatible and/or tissue-compatible material, the system comprising:
- identification and simulation means for identifying and simulating at least a portion of a body in connection with an implantation situation;
a production device which produces a model or die responsive to identification and simulation information provided by the identification and simulation means;
a high-velocity injection-molding apparatus which provides the bone-compatible and/or tissue-compatible material in a powder form through a nozzle; and
controlling means for controlling relative movement between the nozzle and a support member supporting the model or die, wherein the high-velocity injection-molding apparatus is arranged to apply layers of the bone-compatible and/or tissue-compatible material to the model or die via the nozzle during simultaneous movement control of at least one of the nozzle and the supporting member.

Abstract
A system useful in producing a three-dimensional body comprising bone or tissue-compatible material includes a detection and analysis site which identifies and simulates a portion of a body in connection with an implantation situation. A production device produces a model responsive to the simulation information. A flame-spraying apparatus provides the bone-compatible and/or tissue-compatible material in a powder form through a nozzle. Relative movement between the nozzle and a support member supporting the model or die is controlled to apply one or more layers of the bone-compatible material to the model. A method includes using a computer to identify and simulate a body in connection with a given implantation situation, and producing a model or die accordingly the bone or tissue-compatible material is flame-sprayed in a powder form. Movements of a nozzle and/or a supporting member are controlled so as to effect a desired surface characteristic on the three-dimensional body.
