Engraving Acrylic on the Ray5 20W: Cast vs Extruded

Engraving Acrylic on the Ray5 20W: Cast vs Extruded Acrylic looks the same on the shelf but behaves very differently under the laser. Getting this right is the difference between a frosty clean result and a melted mess. Cast vs Extruded — The Key Difference Rule: Use cast acrylic for engraving. Extruded for cutting. Identifying Cast vs Extruded Cast: paper/film masking on both sides, slight cloudy tint when held up to light Extruded: one side masking, very clear and flat Ask your supplier — or test a small corner first Engraving Settings (Cast Acrylic) Cutting Settings Tips 1. Leave masking on while cutting — protects surface from smoke residue 2. Remove masking before engraving — masking reduces mark contrast 3. Air assist for cutting — prevents melting and flaming 4. Defocus slightly for engraving — move bed down 2–3mm for softer, wider marks 5. Flood with water for cold cutting on thin pieces (eliminates melt marks) Common Issues
