CO2 lasers are ideal for laser cutting of acrylics, for example for the production of illuminated or neon displays, billboards, POS / POP displays etc. When laser cutting acrylic the result depends on different components. First of all the material itself, but also the CO2 laser that is used and the performance that this laser cutting machine delivers.

How does laser engraving or laser cutting work on acrylics?

The laser cutting machine produces crystal-clear cut edges and inner contours. Furthermore, no additional post-treatment of the material is required. For cast PPM, this is cut without rough edges. Flame polishing of the cutting edges is no longer necessary. This saves a lot of time and money.

What effect can I achieve with acrylic glass and Plexiglas®?

With the laser it is possible to create even the most fragile figures or photogravures on acrylic. The inner edges are crystal clear and faded. This ensures that the laser user creates added value to the new products.

What about the vapors produced during the cutting of acrylic?

Vapors are immediately extracted and filtered in the engraving area. This saves time while cleaning the system. Unlike cutters, no chips are produced during laser cutting of Plexiglas. This works cost-saving.

Do I have to fix the material to the work surface?

This answer is simply 'no'. The laser does not exert any pressure on the material during the laser process, so it is not necessary to attach or clamp. You can simply place the workpiece and start the laser process. This saves time and money when preparing the material. In contrast, the sheet material must be clamped when milling acrylic. Often fixing with vacuum is also a requirement.

Suitable laser machines

For cutting wood, leather, and a large number of plastics, you have one CO2 laser machine required. Important things to keep in mind are: what is the maximum size of the object that I want to cut out, that determines the size of your worktop and what is the maximum thickness that has to be cut that determines the laser power you need.
