Main Features

3D Stacking

With SLS, you don't need supports anymore. The parts are supported by the unsintered powder which allows for 3D stacking and print in place geometries not possible in other ways.

Functional end use parts with Nylon 12

A materiel that does it all. Flexible, and robust at the same time to cover a wide variety of applications and environments. SLS technology allows printing end-use functional parts in-house, without the need for service bureaus.

Build Volume

a whopping 165mm x 165mm x 300mm build volumes enables printing larger batches and/or larger parts.

High Uptime

Removable and modular build chamber enables continuous printing and reduced downtime

Powder Reclamation
the Fuse Sift, you are able to recover and recycle the powder from the build chamber. Print with up to 70% recycled powder. is now one of Formlabs gold partners
