[0003] SLS printing, full name is selective laser sintering, is a 3D printing technology that selectively melts powder materials on the powder bed by laser energy to realize 3D modeling. A very thin layer of powder material is uniformly laid on the powder bed, then a computer-controlled laser moves according to the 3D model cross-section contour, selectively melts the specific area of the powder with laser energy, and solidifies into a layer. Then, the powder bed is lowered by one layer of powder height, new powder is laid, and the laser melts the new layer and the solidified layer to bond them. Repeat this process until the entire 3D object is built.
