SLS uses a moving laser beam to trace and selectively sinter powdered polymer and/or metal composite materials into successive cross-sections of a three-dimensional part by stacking layers of laser sintered polymer. SLS is a process is used to manufacture extremely complex geometries.
The powder with a polyamide base (nylon) is maintained at an elevated temperature so that it fuses easily upon exposure to the laser which is deposited on a manufacturing platform. The laser beam melts the powder specifically in the areas corresponding to the part. The upper layer fuses to the lower layer during solidification therefore gradually forming the part. The major advantage of this technology is the fact that manufacturing supports are not required, leaving room for your creativity. Shapes are practically limitless with this process
