Cutting vs engraving on metal — the difference and how to choose

What's the technical difference between cutting and engraving?

Cutting passes through the full metal thickness to create a contour or hole. Engraving removes surface material to leave an image; marking is broader and can also involve a colour change. These operations may require different lasers, settings or fixturing, so one-machine processing is not assumed. Assess engraving depth, readability and effects on strength for the part’s intended use.

• Cutting = full separation or opening through the material's thickness
• Engraving — surface material removal to a specified depth
• Marking — a broader term, not always a synonym for engraving

When should you choose cutting, and when engraving?

The rule is simple. If the part needs a new shape, that's cutting. If the part needs information on it, that's engraving. Choose cutting for signage letters, a panel pattern, mounting holes, a keychain outline — anywhere a new piece has to come out of the sheet. Choose engraving when the part already exists or is a plain flat piece and only needs a name, logo, serial number, date, or QR code added. Often you need both: a door plate is cut to size first, then engraved with the apartment number; a name keychain is cut to shape first, then engraved with the name. In that case, order both as one job.

Can cutting and engraving be done on one part at the same time?

Prepare cut contours and engraved elements on separate layers in one vector file. Whether both can run in one setup must be confirmed for the equipment and material. Examples include a shaped award with a name, a door plate with a number, or a business card with an outline and text. When nesting several parts on a sheet, agree spacing and each part’s markings.

Why is engraving sometimes the better choice?

Highly reflective and thin metals — copper, brass, 0.5-1mm aluminum — are more predictable to engrave than to cut with fine detail: beam reflection affects cut precision and edge quality far more than it affects surface marking. So on small decorative items — medals, badges, metal business cards — the usual approach is to cut a simple outer shape from a more stable material such as stainless steel, then engrave all the fine detail. The result is more repeatable than trying to cut the same pattern through a thin, reflective sheet.

How different is the price between cutting and engraving?

They are calculated by different formulas. Cutting price is driven by total cut length, material thickness, and the number of holes; engraving price by the area covered and how detailed the artwork is. In practice, engraving short text and a small logo is faster and cheaper than cutting a complex contour on a part of the same size, though the final ratio always depends on the specific file and the batch size. Confirm the minimum quantity before ordering.
