Dark and opaque acrylic

also: black acrylic, cast and extruded

Black and other opaque acrylic absorbs blue light, which is why diode machines publish cut depths for it. Colour still matters: Glowforge flags white and some blue sheets.

Notes from the pages

Fumes

Every page read treats lasering as a fume source. Match your machine's exhaust figure to an extractor on the fume and room lookup.
