ABSTRACT
Three-dimensional printing (3DP) forming technology can shape personalized porous implant material with complex shape and fine structure to meet the various needs of different patients. In this paper, the green parts of porous titanium implants with diameter 25 mm x 20 mm were prepared using 3DP, and then debinded at 500 degrees C under vacuum. Finally they were sintered in the argon gas at 1 300 degrees C. The pore sizes were observed, and they were between 50-150 microm under SEM. The results of porosity, bulk density, Vickers hardness, compressive strength and elastic modulus were (44.26% +/- 2.43)%, (2.59 +/- 0.81)g/cm3, 134.2-151.6 (61.2 +/- 3.2) MPa, (3.25 +/- 1.08) GPa, respectively. That shows excellent biomechanical compatibility. It is concluded that 3DP has wide application for fabrication of personalized porous titanium implant.
