A comparison of laser engraving and mechanical engraving

When is which engraving process better suited?

Laser engraving and mechanical engraving - a comparison of two technologies

The most common methods for engraving materials are through mechanical engraving and laser engraving. Each technology has its advantages. For example, the primary focus of laser engraving is precision and detail, while mechanical engraving is advantageous in its relief effect. Continue reading to discover a comparison of both engraving methods focusing on their individual advantages and disadvantages.

Mechanical engraving.

In the mechanical engraving process, a milling cutter moves over the surface of the clamped workpiece. The rotary motion of the milling cutter removes the surface of the material. For example, letters or patterns are milled out of a material. Plastic layered materials can also be engraved in this way. Metal surfaces offer a particular advantage in mechanical engraving: The deep machined lettering or decorations can be designed with color to increase the contrast.

Advantages of mechanical engraving.

Deep engraving possible with metals.
Metals can also be drilled and cut.

Disadvantages of mechanical engraving.

The following limits apply to mechanical engraving:

Limited level of detail: Small details, in particular, are difficult to process.
Wear and tear: The milling head wears down and needs to be changed regularly.
Clamping required: For mechanical engraving, the workpiece must be clamped. The time required for this is a hindrance in the production of series.
Not suitable for many materials: Fine engraving or marking of paper or leather are not possible. Mechanical engraving is not suitable for roughening the surface of acrylic.

Examples of paper engraving and photo engraving on acrylic using the laser

Photoengraving of acrylic sheets using a laser

With the laser effective acrylic photo engraving can be realized. The mechanical engraving is not suitable for this.

With the laser fine details can be engraved on paper. The mechanical engraving machine is not suitable for paper engraving.

How laser engraving works

Within a laser engraving machine, light bounces off of mirrors and lenses, focusing on the surface of the workpiece. The axis system allows the beam to glide over the surface. Depending on the length of the exposure, the strong heat of the laser beam marks burns or evaporates the surface of the workpiece. Thus creating an engraving.

Advantages of laser engraving

Suitable for lots of materials (wood, glass, textiles, paper, metal, plastics, etc.)
Material doesn't need to be clamped. Non-contact processing.
No tool wear
Very high precision
Economical for individual pieces and series
