Fabrication method of a novel artificial cortical bone using a multi-pass extrusion process

Abstract

A method for fabricating an artificial bone by multi-pass extrusion, includes: a first extrusion process of forming roll-shaped filaments having sheets of calcium phosphate/calcium phosphate-(t-ZrO2)/t-ZrO2; a second extrusion process of arranging the prepared roll-shaped filaments circularly and extruding the same; and a third extrusion process of forming an external shell of hydroxyapatite (HAp). The method for fabricating an artificial bone allows fabrication of an artificial bone having the biocompatibility and mechanical strength of the natural bone and may be utilized variously in biomedical engineering, medicine and other applications.
