Objective To evaluate the mechanical properties and porcelain bond strength of domestic CoCr alloy specimens based on selected laser melting (SLM) technology. Methods SLM technology was used to construct dumbbell specimens (0°, 45° and 90°) and ceramic specimens. The cast specimens of the same size were made by traditional casting method. Tensile test was carried out at room temperature and the shape of the microstructure was observed. The porcelain bond strength was measured by a three-point bend test, and the metal-ceramic interface was observed by scanning electron microscopy. Results There were significant differences in mechanical properties (including elastic modulus, tensile strength and elongation) among the casting group, the domestic SLM group and the imported SLM group (P < 0.05). In the SLM group, there was no significant difference in elastic modulus, tensile strength and elongation among different fabricated angles. The porcelain bond strength of casting group was 30.78±3.23 MPa, which was lower
