Best wood for laser engraving and cutting
Wood is 80% of what hobby lasers engrave. The difference between a muddy mark and a crisp dark one is mostly the wood, not the machine. Here's what we use and what to buy.
Wood ranking for engraving
| Wood | Engrave contrast | Cut (3 mm) | Notes |
|---|---|---|---|
| Basswood (linden) | ★★★★★ dark, even | Easy | The photo-engraving wood; soft, light, cheap sheets |
| Birch plywood | ★★★★☆ | Best all-rounder | Strong, clean edge; buy laser-grade (no voids) |
| Alder | ★★★★★ | Easy | Premium dark mark, used by Glowforge's Proofgrade |
| Maple | ★★★★☆ light wood, crisp | Medium | Coasters, boards; great with masking |
| Cherry | ★★★★☆ | Medium | Engraves rich brown; premium gifts |
| Walnut | ★★☆☆☆ low contrast (dark wood) | Medium | Beautiful but engrave shows little — inlay or paint-fill |
| Bamboo | ★★★★☆ | Hard | Cutting boards, boxes; dense, needs more passes |
| MDF | ★★★☆☆ | Easy but chars | Cheap, consistent; mask it, extract well |
| Pine / softwoods | ★★☆☆☆ grain-streaky | Easy but chars | Avoid for engraving; resin pockets flare |

Settings and finish tips
- Mask light woods with transfer tape to stop smoke staining; peel after.
- Engrave at lower power/higher speed for contrast; deep ≠ dark.
- Dark mark on light wood: 2 lighter passes often beat 1 heavy pass.
- Finish with a wipe of mineral oil or a matte spray — it pops the contrast.
- Cutting speeds per machine: plywood 3 mm, MDF 3 mm; burn marks: 7 fixes.
FAQ
What wood engraves the darkest?
Basswood and alder give the darkest, most even mark; cherry engraves a rich brown; maple is crisp but lighter; walnut barely shows an engrave because it's already dark.
What plywood is best for laser cutting?
Birch plywood labelled laser-grade (void-free, low-formaldehyde glue), 3 mm for most work, 6 mm for structural pieces. Avoid construction ply — glue voids stop cuts and the glue can be toxic.
Can a diode laser engrave hardwood?
Yes — engraving is easy on any wood with a 5–10 W diode. Cutting hardwood above 3–4 mm is slow on diodes; use a CO2 for thicker hardwood.
