UV Laser Settings by Material
Every UV recipe in the Laser Data Library in one table: 5 starting values across metal, acrylic, glass and other materials. Each row opens the free LightBurn test grid bracketed around its own power and speed, so the first burn on your machine checks the number instead of trusting it.

UV Laser Settings by Material: every recipe
Each row opens the free LightBurn test grid with that row's values filled in. No account needed.
| Material | Machine | Power | Speed | Frequency | Hatch | Passes | Pulse | Evidence | Test grid |
|---|---|---|---|---|---|---|---|---|---|
| STAINLESS STEEL (UV) - Black Mark | UV 5W | 100% | 500 mm/s | 130 kHz | 0.025 mm | 2 | 1 ns | Baseline | Make a test grid |
| ACRYLIC (Clear/Cast) - UV Engrave | UV 355nm 5W | 80% | 400 mm/s | 100 kHz | 0.02 mm | 1 | 1 ns | Baseline | Make a test grid |
| GLASS (Clear) - UV Engrave | UV 355nm 5W | 90% | 300 mm/s | 100 kHz | 0.02 mm | 1 | 1 ns | Baseline | Make a test grid |
| PCB (FR-4) - UV Mark | UV 355nm 5W | 70% | 500 mm/s | 130 kHz | 0.015 mm | 1 | 1 ns | Baseline | Make a test grid |
| ANODIZED ALUMINUM - UV Engrave | UV 355nm 5W | 60% | 600 mm/s | 130 kHz | 0.02 mm | 1 | 1 ns | Baseline | Make a test grid |
Production guidance for UV Laser Settings by Material
These rows come from the same records as the Parameters Library and the settings-by-material tables. All of them are bundled baselines with no vouch or proof-burn photo, recorded on the source and model shown in each row. Wattage, lens, focus and the material finish change the result more than the table can, so treat a row as the centre of a test, not a production preset.
- 1. UV marks cold, so contrast comes from surface chemistry rather than heat. Focus tolerance is tight; a fraction of a millimetre off will wash the mark out.
- 2. Bare metal is unforgiving of focus error: re-zero on the actual work surface rather than the bed, and wipe oils off before marking or the mark will read blotchy.
- 3. Cast and extruded acrylic behave differently at the same settings — cast frosts white and extruded tends to melt, so confirm which sheet you have before trusting these numbers.
- 4. Glass chips rather than ablates. A wet paper mask or dish soap film spreads the heat and is usually the difference between a frosted mark and a cracked piece.
- 5. Change one value at a time. Burn the bracketed grid, pick the cleanest cell, then run a second, narrower grid around it before a customer part.
Source data reviewed 2026-08-09. The test grid link writes the row's power, speed, and any frequency, pulse width, hatch interval and pass count it records into the grid's Constant Values, then sweeps power from half to one and a half times the row's value across and speed the same way down. Burn it on matching scrap, keep the winning cell, and save it in the Parameters Library.
