LASER-PRODUCED POROUS SURFACE

摘要

A method of forming an implant having a porous tissue ingrowth structure and a bearing support structure. The method includes depositing a first layer of a metal powder onto a substrate, scanning a laser beam over the powder so as to sinter the metal powder at predetermined locations, depositing at least one layer of the metal powder onto the first layer and repeating the scanning of the laser beam.

1. A method of forming an implant having a porous tissue ingrowth structure and a bearing support structure, the method comprising:
depositing a first layer of a metal powder onto a substrate; scanning a laser beam over said powder so as to sinter said metal powder at predetermined locations; depositing at least one layer of said metal powder onto said first layer; repeating said laser scanning step for each successive layer until a predetermined structure having a first surface and a second surface is constructed; placing a flowable polymer into contact with said second surface of said predetermined structure; and cooling said flowable polymer such that said flowable polymer adheres to said second surface of said structure.
