How Acrylic Type Affects Laser Engraving and Cutting
When laser cutting, cast acrylic gives a beautiful flame-polished edge that is less prone to crazing (appearance of fine cracks on edges) than extruded acrylic. Laser engraving cast and extruded acrylic also gives much different results. When laser engraved, cast acrylic yields a white engraving, whereas extruded acrylic gives a gray engraving.
