グリーンマシニングによるチタン製品のラピッドプロトタイピング

抄録

A new rapid manufacturing process of metallic parts using green machining has been developed and already achieved for manufacture of stainless steel parts. In this process, metal powder for metal injection molding is hardened by a solution of PVA in water as binder. This green body is prepared for machining. This process is used a small and cost-effective milling machine, and the green body is easily machined. Meanwhile, rapid manufacturing of titanium parts for implant is desired in the medical field. This process makes it possible to produce a suitably sized medical implant. Therefore, we applied the green machining process to the production of titanium parts for the purpose of manufacturing implants with law cost and short lead-time.
