Materials & settings

Power, speed and passes that worked for real people on real material. Filter by your machine and laser type, then run a test tile before you commit a full sheet.

These are starting points from community members, not manufacturer specifications. Materials vary between batches and suppliers, machines drift, and lenses get dirty — always test on an offcut first. Never laser PVC, polycarbonate, ABS or any material you can't identify.
