Laser etching vs. laser engraving
They look similar and the terms get used interchangeably, but etching and engraving are two distinct processes. Choosing the right one comes down to your material, how the piece will be used, and how deep the mark needs to be. Here is how we decide in the Shepherd workshop.
How laser etching works
Etching uses a focused beam to deliver just enough heat to melt the top layer of a material. The surface expands and changes colour or texture, leaving a raised, high-contrast mark while removing almost no material — typically less than 0.001 inch deep. Because so little material is displaced, etching is fast and excellent for fine text, logos, serial numbers, and photo-quality detail. Our systems run at a 1064nm wavelength and hold tolerances to ±0.05mm, which is what makes crisp small text possible.
How laser engraving works
Engraving turns the laser power up far enough to vaporize material, cutting a recessed cavity into the surface — usually 0.005 inch deep or more, and deeper still for industrial traceability marks. The result is a physical groove you can feel with a fingernail. That depth is what gives engraving its durability: the mark survives abrasion, heat, and decades of handling.
The key differences
| Attribute | Etching | Engraving |
|---|---|---|
| Depth | < 0.001" (surface) | 0.005"+ (recessed) |
| Material removed | Minimal — melts surface | Vaporized away |
| Speed | Faster | Slower |
| Detail | Excellent for fine text | Bold, tactile marks |
| Best for | Stainless steel, anodized metals | Wood, tools, deep-wear parts |
| Durability | Permanent, light wear | Maximum, abrasion-proof |
Matching the method to the material
For 304 stainless steel, etching is usually the right call — it produces a clean, high-contrast mark without breaking the passive layer that gives stainless its corrosion resistance. When a stainless part needs a traceability mark that can survive sandblasting or heavy wear, we switch to deep engraving. For wood, engraving wins almost every time: the burned, recessed cavity contrasts against the grain and gives plaques, signage, and keepsake boxes their depth. Glass, leather, and stone each have their own ideal settings, which we dial in during proofing.
Frequently asked questions
- What is the difference between laser etching and laser engraving?
- Laser etching melts and raises the surface of a material to create a mark, removing very little material (typically under 0.001"). Laser engraving vaporizes material to cut a recessed cavity into the surface, usually 0.005" deep or more. Etching is faster and ideal for fine detail on metals; engraving produces deeper, more wear-resistant marks.
- Which is more permanent, etching or engraving?
- Both are permanent. Engraving cuts material away, so the mark survives heavy abrasion, sandblasting, and decades of handling — the standard for tools, firearms, and industrial parts. Etching is also permanent for everyday use and resists fading, but because it is shallow it can wear under extreme abrasion.
- Which process is better for stainless steel?
- Laser etching is the usual choice for 304 stainless steel because it produces a crisp, high-contrast mark without compromising corrosion resistance. For parts that face heavy wear or need traceability markings, deeper laser engraving is preferred.
- Which is better for wood?
- Wood is almost always engraved rather than etched. Engraving burns a visible recessed cavity that contrasts beautifully against the grain, which suits signage, plaques, and keepsake boxes.
