Laser Settings for EVA Foam
Can you laser cut EVA foam?
Yes on a CO2 laser — EVA foam is the cosplay and prop-making staple, cutting cleanly and taking texture beautifully. By defocusing the beam you can bevel-cut edges for seamless armour joins. Diode lasers only manage dark foam, and struggle with thickness.
DIODE450 nm settings
| Variant | Operation | Speed | Power | Passes | Ref. |
|---|---|---|---|---|---|

⚠ CutOnly dark foam absorbs the blue beam — pale foam barely marks.
CO210.6 µm settings
| Variant | Operation | Speed | Power | Passes | Ref. |
|---|---|---|---|---|---|
| EVA foam 5–10mm | Cut | 8–18 mm/s | 50–75% | 1 | 60 W |
| EVA foam | Engrave / texture | 200–400 mm/s | 15–30% | 1 | 60 W |
✓ CutThe cosplay staple. Bevel-cut by defocusing for seamless armour joins.
✓ Engrave / textureGreat for scales, hammered-metal and stone textures.
PrepPreparation & technique
Test your foam is genuine EVA. Some cheap craft foam is PVC-based, which is dangerous — see the PVC safety page. If the listing doesn't confirm EVA, don't cut it.
⚠ SafetyGenuine EVA foam lasers safely with extraction. The real risk is misidentified PVC 'craft foam' — verify before cutting.
