Fuse 1
This 3D printer uses the Selective Laser Sintering (SLS) 3D printing technology. The SLS 3D printing process uses a laser to precisely fuse Nylon powder layer after layer, until the part is finally done.
Fuse 1 SLS workflow
The Fuse 1 is equipped with two separate build volumes or chambers. That means that once one build is completed, users can directly launch a second build while they remove the first one.
This is a real time-saver, as post-processing steps for powder 3D prints can be quite long to carry out. Depowdering happens in the dedicated Fuse Sift, a separate “all-in-one powder recovery” machine that de-powders prints and prepares unused powder for re-use.
In terms of 3D file preparation and printer control, Formlabs offers PreForm desktop software.
