Abstract
Official abstract text for this publication.
An orthopaedic prosthesis and a method for rapidly manufacturing the same are provided. The orthopaedic prosthesis includes a solid bearing layer, a porous bone-ingrowth layer, and an interdigitating layer therebetween. A laser sintering technique is performed to manufacture the orthopaedic prosthesis.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of rapidly manufacturing an orthopaedic prosthesis having a porous substrate, the porous substrate including an outer surface and a plurality of ligaments that define pores beneath the outer surface, the method comprising the steps of: depositing a plurality of metal powder particles onto the outer surface of the porous substrate; allowing at least a first portion of the plurality of metal powder particles to enter the pores beneath the outer surf…
