Line 109: − **Extruded plastics engraved properly will leave a clear finish on top, which is not easy to see on it’s own, and will not edge light. It can also produce a white floss (the white whispy strings of plastic coming off the surface) during the engraving process.+ − **Cast acrylic will make a shiny reflective surface on top that is obvious and visible and will edge light nicely.+

*Acrylic (PMMA): There are two types of acrylic: extruded vs cast. Both cut cleanly, but will produce different results on engraving

*Burn marks: Burns marks might appear behind the cut. To protect the surface of your material, you can tape (use painter’s tape) on the back of the material. If you are cutting a plastic board, then keep the film that it came in on the plastic board to protect the back from creating white floss.
