Is acrylic suitable for laser cutting and engraving?
Acrylic is an extremely versatile material which provides great results when being laser cut or laser engraved. Both extruded and cast acrylic can be laser cut, however extruded acrylic can be left with a slight burr on the edge of the material after laser cutting whereas cast acrylic is left with an extremely smooth edge. Depending on the power of the laser tube it is possible to cut acrylic up to a thickness of 25mm whilst maintaining a square edge. Clear cast acrylic is normally favoured when producing awards and plaques because once engraved it turns a frosty white colour which creates a stunning finish. Certain colours do not react very well when laser cut because the pigment or dye in the acrylic reacts poorly to heat, however the edge discolouration can normally be reduced by modifying settings on the laser such as the cutting speed, the volume of air flow and the amount of power being used.
