How do I remove Surface Armor from SLS printed parts?
Fuse 1 generation printers surround each printed part with Surface Armor, a semi-sintered shell that minimizes potential thermal inconsistencies which can adversely affect your parts.
Media blasting is necessary to remove Surface Armor. Formlabs recommends media blasting your parts with the Fuse Blast or the Fuse Blast Polishing System for the best possible finish.

Use the Fuse Blast to fully clean a whole build chamber of printed parts in as little as 15 minutes and drastically reduce labor time and cost. With the optional Polishing System, polish printed parts to a smooth, semi-gloss, and dye-ready surface finish.
