Abstract: As a new type of advanced technology,rapid prototyping(RP) has been gradually deveolping in recent years.It takes many incomparable advantages in the rapid geometric substantiation,the manufacturing of complex components and so on.Selective laser sintering(SLS) is an important part of RP technology and its forming materials take a crucial role in the technology of selective laser sintering.Considering the attributes of forming materials for SLS,a set of powder-coated equipment for SLS is manufactured and introduced in the paper.Meanwhile,the regulation of equipment parameters and other problems involved are analyzed and discussed.
