The research of a pulse laser powder materials' sintering process

During the research the following problem was raised: to define the pulse laser radiation influence value on different powder materials, as well as to define experimentally the thickness and width relations of a sintered powder layer from technological laser radiation parameters. 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; FDM-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 [1,2,10].
