For example, cast acrylic is appropriate for both cutting and engraving applications, while extruded acrylic is suited for cutting applications only. Extruded costs slightly less; how- ever, it will not frost when engraved and is prone to stress-cracking post-process when using solvents and chemicals. Cast acrylic cuts just as well as extruded but requires higher power settings. All things considered, deciding which acrylic type is best entirely depends on your application. The masking of acrylic also affects the quality of the edges. We recommend leav- ing the protective mask on the acrylic sheet while cutting. This minimizes any hazing or residue on the surface of the acrylic produced during the cutting process. The covering can be either a protective plas- tic film or a paper mask, depending on the type and manufacturer. Be cautious while processing the paper mask as it can be prone to flaming.
