The present paper proposes the greentape laser sintering (GTLS) method that allows us to fabricate metal objects from powder, which is based on rapid prototyping technologies. The novelty lies in the use of a thin tape consisting of fine metal powders and environmentally friendly binders. In particular, a mixture of agar (made of seaweed) and gelatin (animal protein) has been developed as a binder. The present paper firstly describes the method of tape fabrication, and then investigates characteristics of metal objects fabricated using the agar-gelatine tape. It is concluded that the environmentally friendly binder can be replaced by toxic organic binders including PVB (polyvinyl butyral) and DOF (dioctyl phthalate).
