Recently, titanium is known as a hopeful material of the artificial bone. However, a cutting or casting procedure is difficult since its thermal and oxidizing activation are very high. In this research, the artificial bone made from titanium is fabricated by using Green Tape Laser Sintering method (GTLS). Any machining procedures are not needed to fabricate the titanium parts. In order to develop accuracy and strength of the artificial bone, we have examined the laser parameters in sintering procedure. Consequently the influence of warping has improved by changing the laser scanning path. The strength of a single layer can be increased by enlarging pulse width. During the laminating procedure, the warping influence can be reduced by alternating the laser sintering procedure by using low and high energy.
