Engraving on wood, acrylic, slate and metal

We engrave wood, acrylic, slate, anodised aluminium and stainless steel. The lettering sits in the material and does not wipe off. From 1 piece, made in Rottach-Egern.

Three cases that come in regularly

From the trades: tool marking

Company name and a running number on planes, clamps and calipers. Useful when tools move between building sites.

From the hotel: room signs

Slate, aluminium or acrylic in one look for a whole building. The replacement sign in two years looks the same, because we keep the layout.

From the club: trophies and certificates

Crest and year on wood or acrylic, each placing lettered separately. A tournament runs through in one pass.

What we engrave

From a personalised one-off to a consecutively numbered series.

Personalised items

Serving boards, key fobs, picture frames — with a name, a date or a motif. Single gifts included.

Nameplates and control labels

Permanently legible on anodised aluminium or stainless steel: serial numbers, warnings, control panel labelling.

Tool and equipment marking

Asset numbers, QR and Data Matrix codes directly on the part — no sticker that peels off.

Photo engraving

A photograph as a halftone engraving on wood, slate or anodised aluminium — with contrast, not grey on grey.

Diode laser material list — engraving

The diode laser at 450 nm is strong wherever the surface is dark or organic. On metal it only works with marking spray — but then very durably.

CO2 laser material list — engraving

The CO2 laser at 10.6 µm engraves wood, leather, cork, felt and slate, clear acrylic included. It covers larger areas more evenly.

What we do not engrave — and why

Not engravable
MaterialReason
PVC / vinylReleases hydrogen chloride — harmful and corrosive to the machine. Applies to engraving too.
PolycarbonateTurns brown and scorches instead of engraving cleanly.
PTFE / TeflonReleases hydrogen fluoride.
Chrome-tanned leatherCan release chromium VI. We only work with vegetable-tanned leather.
Coated chipboard with unknown surfaceThe coating often contains PVC — without a material declaration we do not engrave it.
Bare metal WITHOUT marking sprayThe beam is reflected; no mark is produced, only stray radiation.

Photo engraving

A photograph becomes an engraving by being broken into a halftone screen — the laser cannot do greys, only dot or no dot. It works best on slate, anodised aluminium and pale wood. Supply the image at at least 300 dpi at final size and with strong contrast; we prepare it and show you a preview beforehand.

File requirements

Two routes lead to an engraving, and they place different demands: a vector file is traced as a line, a raster image is scanned line by line. Logos and type belong in the first category, photographs in the second.

Laser engraving — file requirements
ItemRequirement
Vector engraving (lines)SVG, DXF, AI, EPS or vector PDF — the contour is traced
Raster engraving (areas, photos)PNG, TIFF or JPG at at least 300 dpi at final size
Raster colour modeGreyscale or black and white — colour is converted anyway
TypeConvert to paths (vector) or supply as an image — we do not have your font
Minimum type height≥ 2 mm on wood and metal, ≥ 3 mm on leather and textiles
Minimum line width≥ 0.2 mm — thinner bleeds in wood
Scale1:1 in millimetres; state the position on the workpiece
Engraving areaDiode laser 400×400 mm, CO2 laser 600×300 mm
Round partsThe CO2 laser engraves round parts on a rotary axis up to Ø 120 mm
Your own workpieceGladly — bring the material declaration. No plastics without one.

The recurring mistake in engraving files: type that has not been converted to paths. Your font is missing on our machine, and the laser substitutes another one. Convert the text to curves before you export. For metal there is one more point: we engrave anodised aluminium and stainless steel, bare aluminium does not take the mark.

Frequently asked questions about laser engraving

Engraving removes only the surface; cutting separates the material. That is why many things can be engraved that cannot be cut — stone and metal for example. What can be cut is listed on the laser cutting page.

Yes. Anodised aluminium works directly — the laser removes the anodised layer and the bright base metal shows through. Stainless steel, steel and brass need a marking spray that bonds into the surface and is then rub-proof. Bare metal without spray produces no mark.

Permanent. Unlike print or a sticker, the engraving sits in the material itself — it survives the dishwasher, weather and cleaning agents. On anodised aluminium and with marking spray it is abrasion-resistant too.

Gladly — a serving board, a tool, a key fob. For plastic parts we need a material declaration: we do not engrave PVC or polycarbonate. With unknown coatings we run a test on a hidden spot first.

Yes, as a halftone engraving. It looks best on slate, anodised aluminium and pale wood. Supply the image at at least 300 dpi at final size and with strong contrast — we prepare it and show you a preview.

The price follows the engraved area, the material and the quantity. Lettering on a serving board is a small line item; a full-surface photo engraving on slate is considerably more. Send the motif and the workpiece — you get a concrete price.

Your motif, our laser.

Motif, material and quantity are enough — you get a tailored quote instead of a flat rate.
