Acrylic
This page lists 8 community-tested settings for Acrylic. Acrylic cuts and engraves cleanly on both CO2 and diode lasers. Cast acrylic gives a frosted edge on cuts; extruded acrylic melts and polishes.
Acrylic (PMMA) is a clear or colored plastic that laser cuts with clean, polished edges and engraves with a frosted, matte finish. One of the most versatile laser materials.
Cast acrylic cuts and engraves better than extruded acrylic. Clear acrylic requires a CO2 laser — diode lasers cannot cut clear acrylic. Leave the protective masking on while engraving to prevent scratches and smoke residue.
