Selective Laser Sintering technology (SLS) adopt the selective laser sintering mode, Using a computer model of three-dimensional given path through the layered processing, control the laser point, line, facted sintering solidify layer upon layer overlay, It can manufacture the complicated component arbitrary and quickly. SLS laser sintering rapid prototyping system, used for manufacturing plastic comonents without modul in direct. Molding of plastic comonent with high strength, good surface quality characteristics, Can used for exterior model and function model. 

Advantages: 

1, processing the components is unacted on the degree of complexity , can make any complex components 2, the process is full automaticity, High material utilization. 3, Do not require the special frock and fixture. 4,The fine features can be accurate forming, High forming accuracy , the error is ± 0.1%, 5, compare with SLA , SLS has good material strength, can use the nylon or nylon + fiberglass 

Faults:

matte surface, suitable for strict dimension prototype.
