Abstract
This paper investigates the characteristic of single-layered and multi-layered compacts
made by selective laser sintering using titanium powder. The surface texture and tensile strength
were investigated by using single-layered compacts. There were few defects in surface of specimen
laser sintered in vacuum, and the roughness was smoother than that of the specimen laser sintered in
argon. Maximum tensile strength of single-layered compact laser sintered in vacuum was about
200MPa. The shrinkage and mechanical strength were investigated by using multi-layered compacts.
There was a unique tendency in the shrinkage of multi-layered compacts, which the density was
around 75% and the adhesive bonding was not observed between layers, resulted in 70MPa of
maximum bending strength and 50MPa of maximum tensile strength.
