Laser-based additive manufacturing has a significant impact on the dental industry. Metal 3D printing and post-processing of customized dental products are very relevant due to the growing demand of patients for fast and high-quality treatment. This work is focused on a CAD design and laser powder bed fusion (L-PBF) fabrication of a prosthetic bridge according to the patient’s data. Metal-ceramic crowns are often used to place the prosthetic bridge. Using the high-purity cobalt chromium metal powder, an industrial laser printer was applied to fabricate the specimens and dental prosthetic components. The L-PBF-manufactured dental components were post-processed by thermomechanical technique to provide the material properties and surface integrity. Results indicate that the post-processing induced the porosity reduction in the subsurface layer and a new surface texture formation. The thermomechanical technique improved the surface roughness parameters. Applying mechanical surface treatment resulted in completely removing defects on the heat-treated surface.
