Cast acrylic is better for laser cutting compared to typical extruded acrylic.
The cast results in cleaner cuts and finishes, and the paper masking is smooth to come off after laser cutting.
Acrylic has clear advantages over PET & PVC including higher strength and resistance to heat, cold, and UV.
Before starting your DIY project, here are some tips to keep in mind:
1. Measure and mark the sheet before cutting and peeling
2. Cut the plastic either with a saw that has a suitable blade for plastics or laser cutter
3. Peel the cut sheets afterwards
4. Keep the protective paper film on until ready for use to prevent scratches.
Note: If you stack the sheets without the mask, the materials rubbing against each other can scratch each other.
5. If desired, cut edges can be sanded and polished with a buffing wheel.
