micrometer-scale fabrication

1 millimeter mm one thousandth (10-3) of a meter roughly the thickness of a credit card, a pencil tip, or a blade of grass
100 micrometers 10 thousandths (10-4) of a meter roughly the thickness of a human hair (17-181 μm), or a piece of paper (70 to 180 μm)
10 micrometers 100 thousandths (10-5) of a meter roughly the thickness of a cotton fiber, or a human red blood cell
1 micrometer µm one millionth (10-6) of a meter roughly the thickness of E. coli bacteria, or spider silk

For the machinists out there, note that 1 thou is 25 micrometers.

tools for finishing fine-detailed 3D prints, especially D&D miniatures

This video contains a LOT of wisdom about how to do finishing on miniatures. The miniatures that we're having printed for us are usually made using a resin (SLA / stereolithography) 3D printer.
