SLS PROCESS

SLS started as a commonly used rapid prototyping process that builds solid, three-dimensional parts and patterns in a layered curing process that sinters nylon powder with heat to the geometry of a part in the X and Y axes before the build tray drops to build the Z axis. The machines build from a 3D .stl file, slicing each layer into cross sections prior to the commencement of the build. Parts can be made in one piece in different sizes depending on the size of the platform being used to build the parts.

Evolving from its usage in the RP Industry, SLS used for production additive manufacturing has become the "rapid" method of creating production parts because of its ability to build parts without support structures and with little post finishing required. As designers and engineers gain a better understanding of the technology, and learn where and how it can be used, it subsequently lowers the cost of doing business for their organizations. This is accomplished because this type of manufacturing eliminates the need for fabricating and maintaining tooling.
