This paper presents an integrated system for bioceramic implant modeling and printing. To actualize the concept of " Made-to-order implants - customized body parts", Spline based volumetric modeling, new approaches and applications of volumetric modeling and Rapid Prototyping in medical implant, is effective in constructing/reconstructing the normal and defective bone structures and to interface the constructed/reconstructed medical models for rapid prototyping.The feasibility of using the 3DP technique for the near-net-shape fabrication of biocomposite bone implants is demonstrated. Developed in this project is the printable bioceramic-based composite material consisting of hydroxyapatite Ca10(PO4)6(OH)2 particles coated with poly vinyl alcohol. This new material system is biocompatible in the human body and is found to have compressive strengths similar to the native bone. Two types of infiltrant were also developed to strengthen the printed parts of the newly developed powder. Biocomposite formulation, fabrication and characterized, mechanical testing, and 3DP process application are also discussed in the paper.
