Production guidance

This ACRYLIC (Dark/Black) - Diode Engrave acrylic record pairs 75% power with 100 mm/s on Diode 450nm 10W, using 1 pass, machine default frequency, 0.1 mm hatch spacing, and no recorded pulse-width override. Compare every listed field with the source, lens, focus method, and material finish on your machine before transferring the recipe.

1. 1. Dark/opaque acrylic ONLY. 450nm cannot process clear acrylic. Source: LightBurn forum & delviesplastics.com (2024).
2. 2. Treat this as an unverified baseline, not a production preset. A VERIFIED Parameters Library record requires three independent community vouches; an attached proof-burn image provides additional evidence.
3. 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. 4. Diode sources need slower speeds and more passes than fiber or CO2 for the same result, and a spot that is genuinely in focus matters more than raw wattage.
5. 5. Change one variable at a time — power, then speed, then frequency — so you can attribute the improvement when you find it.
6. 6. Record the successful result in the Parameters Library so the next production run is repeatable.

The bundled note for this ACRYLIC (Dark/Black) - Diode Engrave recipe is: “Dark/opaque acrylic ONLY. 450nm cannot process clear acrylic. Source: LightBurn forum & delviesplastics.com (2024).” The source data was reviewed 2026-08-09; no independent vouch or proof-burn image is attached. Label the scrap test with the adjusted values and keep the accepted result with the production job.
