Laser & material guide

Recommended starting points for diode, fiber, and UV lasers (CO2 included) across popular blanks. These are conservative baselines — always run a test swatch on scrap of the same material first.

Suggested laser setup

Mode: Grayscale 3D / "depth" mode — turn OFF dithering. White = highest surface, black = deepest cut.
Resolution / DPI: 318 DPI · 0.08 mm line interval (preserves fine detail)
Passes: 2–3 passes for full relief on this highly detailed map

Lots of fine detail here — slow down 10–15% and keep focus tight. Run a small power-ramp test before committing to a large blank.

Material settings & relief depth

Starting points for diode, fiber, and UV lasers (plus CO2). Always test on scrap first.

Basswood / Birch ply0.6–1.2 mm

Diode ~10–20W

Speed3000 mm/minPower35% maxPasses1–2 passes

Great value for wood relief — map MIN power to white, MAX to black for the full depth range.

Fiber / MOPA ~20–50W

Speed1000 mm/sPower60–80%Passes3–6 passes

Use ~30–60 kHz. Fiber chars rather than vaporizes wood — best on darker species; expect more scorch than CO2.

UV ~3–5W (355 nm)

Speed800 mm/sPower45–65%Passes1–2 passes

Cold marking — crisp, light-tone detail with almost no scorch. Excellent for fine faces/fur, but relief stays shallow (surface tone). Ideal for highly intricate maps.

CO2 ~40–60W

Speed300 mm/sPower22% maxPasses1 pass

Hardwood (walnut, oak, maple)0.8–1.5 mm

Diode ~10–20W

Speed2200 mm/minPower55% maxPasses2–3 passes

Higher-wattage diodes (20W+) reach full relief in fewer passes on dense hardwood.

Fiber / MOPA ~20–50W

Speed800 mm/sPower70–90%Passes5–10 passes

Use ~30–60 kHz. Dense hardwoods take fiber relief well but darken heavily — sand or finish after for contrast.

UV ~3–5W (355 nm)

Speed600 mm/sPower55–75%Passes2–3 passes

Sharp, low-char tonal detail on figured grain; shallow relief only. Best when you want photographic crispness over depth.

CO2 ~40–60W

Speed250 mm/sPower30% maxPasses1–2 passes

Cast acrylic0.5–1.0 mm

UV ~3–5W (355 nm)

Speed1000 mm/sPower30–50%Passes1–2 passes

UV's standout material — engraves clear AND colored cast acrylic with a clean frosted relief and no melted edges. The best choice here.

Diode ~10–20W

Speed2800 mm/minPower40% maxPasses1 pass

Use black-cast acrylic; clear acrylic does not engrave with a diode.

Fiber / MOPA ~20–50W

Speed1500 mm/sPower30–50%Passes2–4 passes

Works on most cast acrylics but melts edges more than UV/CO2; keep speed high and power low.

CO2 ~40–60W

Speed350 mm/sPower25% maxPasses1 pass

Engrave from the back for a clean front-facing relief.

Slate / stoneSurface tone only (~0.1 mm)

Diode ~10–20W

Speed2500 mm/minPower80% maxPasses1 pass

Fiber / MOPA ~20–50W

Speed1000 mm/sPower40–60%Passes1–2 passes

Use ~40–80 kHz for a frosted light-tone mark.

UV ~3–5W (355 nm)

Speed700 mm/sPower50–70%Passes1 pass

Bright, high-contrast frosted tone with fine gradient control — superb for portraits on dark slate. Tonal only, no depth.

CO2 ~40–60W

Speed400 mm/sPower35% maxPasses1 pass

Slate is tonal on every laser — no true relief depth.

GlassFrosted surface tone (~0.05 mm)

UV ~3–5W (355 nm)

Speed900 mm/sPower40–60%Passes1 pass

UV frosts glass cleanly without the micro-fracturing/chipping that diode and CO2 cause — the recommended laser for glassware and tonal portraits.

CO2 ~40–60W

Speed350 mm/sPower25% maxPasses1 pass

Wet paper / dish-soap coating reduces chipping. Tonal only.

Fiber / MOPA ~20–50W

Speed—Power—Passes—

Fiber (1064 nm) passes through clear glass and will not mark it.

Diode ~10–20W

Speed—Power—Passes—

Diodes do not engrave clear glass without a coating/marking spray.

Leather (veg-tan)0.3–0.6 mm

Diode ~10–20W

Speed4000 mm/minPower25% maxPasses1 pass

Fiber / MOPA ~20–50W

Speed2000 mm/sPower20–35%Passes1–2 passes

Use ~30–60 kHz. Crisp dark mark; keep power low to avoid burning through thin hides.

UV ~3–5W (355 nm)

Speed1500 mm/sPower20–35%Passes1 pass

Clean, low-odor light mark with excellent tonal detail and minimal heat distortion on thin or dyed leather.

CO2 ~40–60W

Speed450 mm/sPower15% maxPasses1 pass

Brass0.15–0.4 mm (true 3D relief)

Fiber / MOPA ~20–50W

Speed~1800 mm/sPower80–100%Passes~265 passes

The only way to get true 3D depth in brass: start ~38 kHz, 0.02 mm line interval, ramp passes from coarse to fine. Air assist + frequent debris clearing.

UV ~3–5W (355 nm)

Speed500 mm/sPower70–90%Passes1–3 passes

High-contrast cold surface mark on bare brass — sharp tonal detail, but essentially no relief depth.

Diode / CO2

Speed—Power—Passes—

Cannot engrave brass. Both only surface-mark with marking spray (e.g. Cermark) — no relief.

Stainless steel0.1–0.3 mm (true 3D relief)

Fiber / MOPA ~30–50W

Speed200–400 mm/sPower90–100%Passes25–60 passes

True 3D depth: ~40–60 kHz, 0.02 mm line interval, multiple slow passes. Air assist required; expect dark oxide unless cleaned/polished after.

UV ~3–5W (355 nm)

Speed400 mm/sPower80–100%Passes1–4 passes

Permanent high-contrast black/grey cold mark with crisp gradients — great for photo-style plaques, but surface only (no relief).

Diode / CO2

Speed—Power—Passes—

Cannot engrave steel. Both only anneal or mark with spray — no relief.

Pick your laser, then your material. Diode (10–20W) is the budget all-rounder for wood relief; fiber/MOPA is the only laser that deep-engraves metal in true 3D; and UV (355 nm) is a cold laser that marks acrylic, glass, slate, and bare metal with photographic crispness and almost no scorch — though its relief stays shallow (surface tone). CO2 remains a clean choice for acrylic and wood. The same grayscale file removes material at different rates per surface: soft woods and leather cut deep and fast, hardwoods need more passes, and slate and glass register tone rather than depth. Always map your laser's MIN power to white and MAX power to black, then run a test swatch on scrap of the same material before the final burn.

Engraving tips

Get a flawless burn

Engrave in grayscale / 3D depth mode — white is the highest surface, black the deepest cut.
Run a small test tile first to dial in power and speed for your specific material.
Use multiple passes on hardwoods and metal for deeper, more sculptural relief.
Keep the focal length consistent across the piece for even, true-to-art depth.
