This paper investigates the characteristic of single-layered and multi-layered compacts made by selective laser sintering using blended bimodal titanium powders. The surface texture and tensile strength were investigated by using single-layered compact. There were few defects in the surface of specimen sintered in vacuum, and the roughness was smoother than that of specimen sintered in argon. Maximum tensile strength of single-layered compact sintered in vacuum was about 200 MPa. The shrinkage and mechanical strength were investigated by using multi-layered compact. There was a unique tendency in the shrinkage of multi-layered compacts, which the density was around 76% and the adhesive bonding was not observed between layers, resulted in 70 MPa of maximum bending strength and 50 MPa of maximum tensile strength.
