The interest of the additive manufacturing technology, commonly called 3D printing, is rapidly increasing. Selective laser sintering (SLS) is the one of the method for 3D printing that has potential to produce metallic prostheses in dentistry. The purpose of this study was to evaluate physical properties of titanium specimen fabricated by SLS for dental implant system. Specimens were fabricated from Ti6Al4V alloy powder with median particle size (D50) of 34 μm. The SLS 3D printing was carried out using YAG laser with wavelength of 1075 nm with power of 190 W, and thickness of each layer was 30 μm. Machined specimens with sandblasting treatment were used as control group. Density, porosity, yield strength (30o compression), elastic modulus and fatigue limit were estimated. Density measurement and microCT analysis gave valuable informations about impurity inclusions and manufacturing defects. Yield strength and elastic modulus of 3D printing dense specimen showed similar value with the machined specimens. However, fatigue limit of 3D printing dense specimens was significantly lower than the machined specimen. 3D printing porous specimen showed lower yield strength and elastic modulus than the 3D printing dense specimens. Before 3D printing porous dental prosthesis application in clinic, fatigue limit should be evaluated carefully.
