Yes, it cuts cleanly with CO2 lasers at low power, producing smooth, glossy edges for detailed designs like signs or diffusers. Can I use this outdoors? Yes, cast acrylic is UV-stable and weather-resistant for indoor and limited outdoor use, but prolonged exposure to moisture may require sealing for longevity. Is it safe for school projects? Yes, acrylic is non-toxic and safe for general use, but ensure proper ventilation when laser cutting due to fumes. It is not food-safe unless specifically certified. Can I paint or engrave it? Yes, the surface can be painted with acrylic-compatible paints or engraved with lasers for custom designs. Can I use a diode laser? No, diode lasers cannot cut through light color opaque acrylic sheets. How does this differ from extruded acrylic? Cast acrylic is stronger, more resistant to cracking, and cuts with glossier edges compared to extruded acrylic, making it ideal for laser cutting and high-quality projects.
