3D printed model made of metal
The technology of direct printing of metal materials, materials and machines is much more difficult than printing of plastics. At least it is rarely seen in commercial printing at present. It is a laser sintering technology. A layer of metal powder is burned once with a laser, cooled and then burned One layer, layer after layer to reach the target size. This technology is suitable for printing some mold parts with complicated heat dissipation pipes inside, or a few parts that are complicated to the traditional process and are difficult to achieve.
