Tasks between uses

Recovering sintered nylon powder mobilizes loose powder and byproducts of SLS printing
such as off-gases and laurolactam, which collect onto Fuse Sift's sifter mesh and vent filter.
In order to preserve the reliability of Fuse Sift, it is important to regularly inspect and clean
affected components and assemblies.
