Traditional manual technology for the manufacture of denture metal inner crowns requires 17 processes such as stamping, waxing, casting installation, embedding, and wax loss. Hallem 3D printing technology reduces the need for multiple manual processes and traditional auxiliary materials, reducing manufacturing costs. . Hallem's cobalt-chromium alloy dentures are excellent in terms of tensile strength of 1193 MPa and density close to 100%. It is easy to achieve the "beauty" and "quality" of denture products. At the same time, the teeth made by 3D printing have a distinct and unique advantage in the car gold segment.
