Recently, it has been recognized that treatment using regenerative medicine is a powerful tool for bone diseases, in which osteoblasts or osteogenic cells contained in transplant materials lead to the rebirth of positive bone tissue. The aim of this research is to manufacture artificial porous bones with titanium for the substitution of autologoas bones. Although the Greentape Laser Sintering (GTLS) method can be utilized for this purpose, some problems have arisen, including presice control of porous structures and dimensional accuracy. The main reason is the quality of the greentape. The mask printing method is successfully applied to the forming of a thin greentape with uniformly distributed titanium powder.
