Often when finishing FDM 3D prints, I flame polish them, a trick I learned from acrylic manufacturing, to eliminate the print lines and create a nice gloss finish.
Stumbled across the video below of someone doing the same with a laser strapped to their printer. Seemed like a perfect match for Snapmaker 2 and Artisan.
