A few weeks ago, @Drea gifted me some bone beads and I finally had a chance to do some test prints.
Each bead is about 1/2" (~12.7mm) across and although each engraving was at different settings, they probably averaged about 3/335/340. All were SVG icons except the – it was a .png
Folks have asked about the smell… While in the GF, I actually didn’t notice it at all. Engraving low and fast didn’t really make much smoke (but boy howdy were there a lot of sparks!), and now immediate odor. On the other hand, there was a definite odeur du dentiste thing going on when I removed them. No worse than a root canal.
