SLS 3D Printed Parts in Powder

Best of both worlds

Selective Laser Sintering (SLS) parts boast both mechanical strength and aesthetics

Typically printed in Nylon, SLS is a powder-based process that has been around since the 80s and produces complex, organic geometries due to the lack of necessary support material.

This method works well for end-use functional parts, has a large build volume compared to other powder-based 3D printing technologies, is easy to be dyed in vibrant colors, and has isotropic mechanical properties.

How It Works

An overview of the SLS 3D printing process

SLS is a powder-based 3D printing system that starts by spreading a thin layer of powder over the build plate. Then, using layers, sinters the cross-sectional area of the part for that layer, fusing point to point.

This layer drops and a new layer is started. The build is cooled, extracted, and excess powder is removed with glass media bead blast. This creates the natural finish look for SLS parts.
