SLS (Selective Laser Sintering) is a 3D printing technology in which the shaping of the final three-dimensional products is done by a laser that manipulates a special powder. The objects are built by superimposing thin layers of polymer powder, as on each layer, a laser beam passes through the powder and hardens it, following a predefined pattern. Unlike FDM or other 3D printing technologies, SLS does not require the use of supporting structures, as the manufactured objects are completely surrounded by powder.
SLS technology is ideal for complex structures with moving parts, active mechanics and functional details. Allows the application of colors during 3D printing, which expands the possibilities of application.
