Is cast acrylic good for laser cutting?

Yes! Cast acrylic is a great material choice for laser cutting. The material produces smooth, clean edges when cut with a CO₂ laser like a Glowforge, and engraves with a frosty white contrast.

Can a Glowforge engrave plastic?

Yes, a Glowforge performance laser can engrave many types of plastic, including cast acrylic. Always make sure the plastic you're using is laser-compatible and safe, as some plastics like PVC release toxic fumes when cut. For best results, use Proofgrade acrylic or materials marked on jpplus.com as laser-safe.
