Selective Laser Sintering (SLS)

Invented in the mid-80's, SLS, or the Powder Bed Fusion process creates the most uniform performance properties and is a great choice for functional prototypes and production applications.

About Selective Laser Sintering (SLS)

We've seen laser sintered parts used in agricultural environments, off road vehicles, for under the hood testing, functional parts in lab equipment, race cars and aircraft.  

Selective Laser Sintering (SLS) is an additive manufacturing process that creates 3D components from powdered material. A laser is used to heat and fuse the powder one layer at a time, creating a solid structure.

Laser Sintering produces functional production components, eliminating the need for tooling and the investments of time and capital that go along with it. This leads to economic savings and quick turnaround as parts can be ordered with short lead times and with no penalty for design changes.

The final components are ideal for use in harsh environments and demanding applications. 

Build Specs

We have multiple laser sintering machines on site, with our largest build envelope is 26" x 13.8" x 21.8". That's a really big part or many, many smaller ones. As with most additive technologies, even larger parts can be built in sections and assembled.

SLS Materials

Our most popular material is the base nylon (PA), a bright white strong and flexible material. Very versatile, this material is flexible in thin sections, and stiff in thicker sections. It can be drilled and tapped easily and will accept thread forming screws and heat staked inserts.  We also offer glass filled (GF) nylon and aluminum filled nylon.

SLS Tolerances

Expected tolerances on our SLS models are +/- .005” for the first inch and +/- .002” for each additional inch.  Part geometry, wall thickness, and build orientation can have an effect on tolerances.  Please let us know if you have critical dimensions that need to be met.
