Laser Techniques
Laser processing varies based on the absorption rate of the specific laser wavelength by the target material and the technique selected for the application. Trotec offers a wide variety of wavelengths to address the expansive range of materials available to today’s manufacturers. By adjusting the parameters of the laser, it can be used to accomplish the following techniques:
Laser Engraving
Laser Cutting
Ablation
Annealing
Burning
Foaming
Color Change and Bleaching
Laser Engraving
During the laser engraving process, the target material is essentially vaporized by the laser beam. To achieve this result, the intensity of the laser beam is set to exceed a specific threshold value. This threshold intensity is particularly high with materials that are electrically conductive, such as metals. The result is often a cone-shaped indentation influenced by the laser beam profile and the heat conductivity of the target material. The laser engraving technique is typically the fastest way of processing material.
Laser Cutting
With laser cutting, a plate-type material is separated by a focussed laser beam. Basically,
there is a choice between laser beam fusion cutting and laser beam sublimation cutting. With
laser beam fusion cutting the material, e.g. acrylic, is melted or vaporised. With sublimation
cutting, the material, e.g. wood, is vaporised by missing out the liquid phase.
Ablation
During the ablation process, a covering layer evaporates. Very thin covering layers such as
color and/or anodizing layers are especially suited for laser engraving. High contrasts can be
achieved with a small amount of laser power since these layers absorb laser radiation
extremely well. With varnished plastics, a "day & night" design, e.g. for car dashboards, can
be achieved by removing one color layer.
Annealing
A contrasting mark can be created using an annealing effect on metallic target materials. The
laser beam heats up the metal, creating structural changes in the surface. The color of the
mark is determined by the maximum temperature attained in the metal, the properties of the
metal, and the parameters selected on the laser. The annealing technique has a unique
characteristic in that it produces a contrasting mark without disrupting the surface finish of the
metal.
Burning
Metal engravings can be made by burning covering layers using ceramic powders (Trotec
MetalFix). The covering layer is sprayed on and removed again after the laser engraving
process. Using this procedure, metal surfaces can also be engraved with a high contrast CO2
laser. In the case of metals, an oxidation process takes place on the surface. However, there
is also a powder available on the market for glass engraving with a Nd:YAG laser.
Foaming
Sometimes the best technique to process a material is foaming. Most commonly used in certain plastics, foaming is easily recognizable because the surface of the affected area is raised. Melting occurs when the laser beam couples with the target material. During the process, gas bubbles form and get trapped as the target material cools, producing an elevated result.

Colour Change and Bleaching
This effect is only possible with plastics, and depends highly on the wavelength of the laser radiation used. In most cases, this effect is only possible with an Nd:YAG laser, or a specific type of Nd:YAG laser (double-frequency laser). During this process, the laser radiation penetrates the plastic and is absorbed by the color pigments. As a result, the pigments are chemically modified, resulting in a color change in the material. Since the laser radiation penetrates into the plastic, the surface remains almost undamaged. The color change achieved depends on both the pigment and the basic material used.
Trotec MetalFix
MetalFix is a special emulsion that enables permanent laser engraving of blank metals (e.g. stainless steel, brass, etc.) using a CO2 laser.
Because it can be mixed with water, MetalFix is highly economical – 17.5 ounces (500 g), for example, will yield 1,000 2.4 x 3.2 inch (80 x 60 mm) signs. Simply apply, dry, and engrave, then remove any extra material. An added bonus: the leftover MetalFix can be washed and re-used for other projects!
Available in bottles of 7 and 17.5 ounces (200 or 500 g).
