Laser Engraving Veg-tan leather: Diode Settings by Machine
Vegetable-tanned leather engraves at low power with rich contrast and cuts thin for patches, keychains and wallets.
How a diode laser handles veg-tan leather
The laser burns the surface to a dark brown, so natural undyed veg-tan gives the highest contrast. It needs very little power; too much chars and smells badly. Thin leather cuts with sealed, dark edges. Chrome-tanned and PVC faux leather must not be lasered.
Before you start
- Confirm the leather is veg-tan; if you can't, don't laser it
- Flatten and weigh down the edges; leather curls
- Mask with transfer tape to limit smoke staining
- Vent outside or use a carbon-filter extractor; leather smoke lingers
Starting points, not gospel. Rows marked “starting point” come from manufacturer tables and community results. Run a small power/speed test grid on your own sheet before a real job — batch, humidity and focus all shift the result.

Tips
- Low power, high speed: start lower than you think
- Wipe soot off with a damp cloth and condition afterwards
- Dye after engraving for a two-tone look
Frequently asked questions
Can you laser faux leather?
Only confirmed PU leather without PVC. Many faux leathers are PVC-based and release toxic, corrosive fumes. When in doubt, no.
Why does my leather engraving look blotchy?
Natural variation in the hide, or oils on the surface. Wipe with a dry cloth, test on the same piece and keep the power low.
