The ComMarker B6 20W UV is a 20W uv laser engraver. This page lists 35 community-tested settings covering speed, power, passes, air assist, and DPI across a range of materials. Always run a test cut on scrap material first: results vary depending on your material batch, focus, and ambient conditions.

The ComMarker B6 UV is a 20W UV laser (355nm) that marks glass, ceramics, stone, and plastics cold: no coating needed, no heat damage. UV lasers are photochemical so they leave clean, fine marks on materials that thermal lasers struggle with. The B6 is used for personalising wine glasses, mugs, phone cases, and acrylic awards. An affordable way to add glass and plastic marking to a laser business.
