SLS 3D Printing

SLS (Selective Laser Sintering) 3D Printing is a method that uses powdered thermoplastics most notably, nylons. This allows the use of actual plastics like FDM 3D Printing but with higher precision. Layer by layer a laser melts the powder into a part, since each successive layer rests on the previous powder base, supports do not need to be used in this method which makes it more affordable than resins. However, since the parts are made from powder, finished parts tend to have a slightly rough surface akin to extremely fine sandpaper.
