Extruded acrylics do not frost when laser engraved. Engraving is very clear. Most often extruded acrylic is used when the engraved areas are to be color filled because of the clear nature of the engraving. If reverse engraved, this clear engraving will not distort or shade the filled areas. Engraving settings are similar to cast.
Extruded acrylic does have an advantage in edge clarity when laser cut.
It is much more smooth due to the lower melting point. Beware of some abrasion resistant forms of acrylic. They can produce tremendous flames and lots of black smoke. An air nozzle is a good addition to your machine for these materials. Return to top Glass - glass, glass and more glass.
