Porous Ti-6Mo alloy was prepared from mixed powders of Ti, Mo and binder by selective laser sintering, then the structural and mechanical characterizations were investigated. The results show that the pore features are connected with sintering process. As the sintering temperature rises from 1000 to 1200 °C, the pore morphology changes gradually from interconnected to isolated pores, and the porosity level reduces from 58% to 24%, as well as the pore size from 112 to 43 μm. The porous alloy exhibits a laminar microstructure composed of dominant α and minor β phases together with trace amounts of α-Ti precipitations. The compressive stress-strain curves consist of elastic deformation, plastic yield and fracture stage. The elastic modulus and yield strength increase respectively in the ranges 2.07-11.9 GPa and 31.4-152.8 MPa with decreased porosity, meanwhile the relationship between the relative mechanical properties and relative density conforms to a power law relation.
