Fibre laser engraving — metal, glass & slate
Fibre lasers do what CO₂ lasers can't: mark and engrave metal. The beam interacts with the metal surface itself, leaving a permanent change in the substrate — not a coating, not a print, not an etch. That's why fibre-marked jewellery, knives and industrial parts survive years of cleaning, wear and weather.
We run a fibre laser station in our Leith workshop, alongside our CO₂ cutter and MOPA marker. We engrave metal, glass and slate for designers, distilleries, jewellers, fabricators and industrial clients.
What fibre engraving is good for
- Brand plaques and signage on metal
- Awards and corporate-gift personalisation
- Knife blades, watch backs, pen barrels
- Distillery and brewery bottle marks
- Slate coasters, drink-mats, address plaques
- Glass etching — frosted or photographic-style
- Architectural hardware and brackets
Materials and what the mark looks like
- Stainless steel — annealed dark mark, polished bright mark, or deep engrave. See our stainless page.
- Anodised aluminium — colour-removed white-on-colour mark. See our anodised page.
- Brass and copper — soft engrave, takes infill paint cleanly
- Mild steel — dark oxide mark or deep engrave
- Titanium — strong contrast, accepts MOPA colour
- Glass — frosted appearance, good for logos and addresses
- Slate — high contrast off the dark surface, very durable outdoors
Annealing vs. engraving
Two different marks come off the same machine:
- Annealed mark — heat-changes the surface to a dark grey or black without removing material. Smooth to touch, food-safe, ideal for medical and culinary parts.
- Engraved mark — physically removes a small amount of metal. Tactile, deeper contrast, takes paint infill. Best for industrial and outdoor pieces.

What we don't engrave on the fibre
Wood, acrylic, leather, paper — all go on our CO₂ laser instead. See CO₂ laser cutting.
