Notes:
Rapid Prototyping (RP) technique was used to prepare porous Ti6Al4V with designedstructures. Firstly, a 3-D interconnected porous wax mold with uniform pore size and porosity wasdesigned by computer aided design (CAD), and fabricated by 3-D printing machine, then an aqueousTi6Al4V slurry prepared from Ti6Al4V powder and binders was cast in these molds. The greenbodies were subjected to drying, debinding and finally sintering at a high temperature and a highvacuum to obtain porous Ti6Al4V. Optical microscopical observation, scanning electronicmicroscopical observation, mechanical test were performed on the obtained porous Ti6Al4V withregard to the porous structures and mechanical properties. The porous Ti6Al4V made by RPtechnique posses designed structure with uniform pore size, porosity and interconnection. With thecomputer aided design, it is easy to improve the mold structure with predicted or controlledmacrostructure and microstructure according to the custom requirement
