The lazer powder materials' sintering process

At present there are various methods of rapid prototyping. Different physical processes and materials for making prototypes are employed: stereo-lithography - layered hardening of liquid monomers with UV-laser beam trough light influence: LOM method employs sheet materials cut with laser beams; FDIVI-method - layered covering of melted polymer fibers; selective laser sintering - SLS. At the last process prototypes are made from sintered powder materials under thermal effect of laser beam.
