Powder Bed Fusion Technology

Selective Laser Sintering (SLS) technology is a powder-bed fusion AM technology that allows for the production of impact resistant, accurate, functional products and parts, with high geometrical complexity. Similar to MJF, SLS technology does not require support structures, thus enabling the design of complex geometries without additional costs, which would be expensive or not even possible to produce with traditional manufacturing processes, as the powder itself acts as support.

How It Works?

The Selective Laser Sintering (SLS) process begins with the build chamber being heated to below the melting point. The work area contains a layer of powder.

A laser source is directed at a lens or a mirror that directs the laser onto the work area. The laser selectively fuses powdered material by heating it up beyond the melting point and scanning X&Y cross-sections on the surface of a powder bed.

Then, the work area lowers, and the fresh powder bed raises slightly. Fresh powder is spread across the top of the work area. The steps repeat until the entire build is complete.
