During the process of 3D printing SLM prototype, the metal powder is melted by the heat of laser, and the prototype will be done after cooling and congealing. Equipped with 500 watts fiber optic, collimating system and high precision scanner, the precise facula and optical quality can be got. Therefore, 3D printing SLM prototype is preciser than SLS. The only difference is that the materials are titanium alloy, stainless steel, aluminum alloy, cobalt-chromium alloy or steel, so the price is higher.
