Guide to choosing powders for SLS 3D printing

The Selective Laser Sintering 3D printing technology allows us to bring the polymer powders to temperature and sintering using the heat generated by one or more lasers that can be moved with galvanometers, guaranteeing a surface finish, precision and mechanical characteristics that are difficult to match with other technologies.
