Selective Laser Sintering (SLS)

SLS is one of the original 3D printing technologies using thermoplastic powder and UV lasers to create prototypes and end use production parts.

What is Selective Laser Sintering?

The Selective Laser Sintering process, also known as just laser sintering (LS), is best used for small to medium sized prototype parts and end-use production parts. SLS or LS is one of the oldest additive manufacturing technologies. It sinters thermoplastic powders with a UV laser to create pieces from engineered materials like nylon, glass-filled nylon, and others. Parts are typically rougher with a gritty finish but are tough and strong.
