Acrylic is very similar to glass, but it surpasses it in its quality characteristics. For example, the weight of acrylic is 2.5 times less, and the impact resistance is 5 times higher. Its light transmittance reaches 92%, so acrylic is used as a replacement for glass. At the same time, it is much more difficult to cut natural glass than to carry out laser cutting of acrylic. 

Laser cutting of acrylic allows you to cut products of almost any shape.

Products made with the help of laser cutting of acrylic can be found everywhere — from shops to your own home. Thanks to the laser cutting of acrylic, we see price tags in stores, shop windows, advertising, packaging, elegant lamps with 3D effect, and sometimes we even take acrylic for ordinary glass.

In this article you will read about how CNC acrylic laser machines work, why and how acrylic laser cutting is generally possible, what types of acrylics there are and which type is better to choose.

How does laser cutting of acrylic work?

Acrylic Laser Cutting MachineLaser cutting of acrylic. How and why does an acrylic cutting laser machine work? 1

Laser cutting of acrylic occurs due to the impact of a focused laser beam on the surface of the material. For this purpose, special CO2 laser CNC machines for acrylic are used. 

Why is the acrylic laser machine called CO2

At the heart of the acrylic laser cutting machine is a carbon dioxide emitter — a multilayer glass flask with a mixture of gases, the main of which is carbon dioxide. Gases in this case are the active medium, which, under the influence of electricity, forms a laser beam for the implementation of laser cutting of acrylic.

What is a CNC

CNC means Numerical Program Control, in this case it is a way of coordinating all the moving parts of the laser machine on acrylic and activating laser radiation at the right moment at the right percentage of power to carry out laser cutting of acrylic.

To understand how laser cutting of acrylic is possible and to illustrate the principle of operation of a laser machine on acrylic, you need to imagine its design. 

The principle of operation of the acrylic laser cutting machine

To carry out laser cutting of acrylic, a sheet of material is laid on the working field. The emitter of an acrylic laser machine is usually located in the back of the housing under a closed lid, separate from all other units of the acrylic laser machine.

In order to direct the generated laser beam to the desired point of the working field and carry out laser cutting of acrylic, a system of movable mirrors is used. The first mirror is fixed directly at the laser emitter, it receives the outgoing laser beam and directs it to the second mirror, which is fixed on the portal and moves with it along the Y axis. 

The beam is reflected from the second mirror and passes to the third, mounted on a laser head that moves along the portal along the X-axis. The last third mirror directs the laser beam strictly perpendicular to the working field through the focusing lens to the material.

By moving the machine portal and the working head along the portal, the control system of the acrylic laser machine has the ability to direct the beam to any point on the coordinate table.

How does laser cutting of acrylic work?

The focused beam of the acrylic laser machine has a diameter of 0.03 mm and, due to this, a high power density. This means that on a small area of the material during laser cutting of acrylic, there is a high intensity of exposure.

An acrylic laser cutting machine supplies an air stream to the cutting zone, which helps the laser beam burn through the material, and also blows out combustion products (carbon deposits and acrylic vapors) from the acrylic laser cutting zone. 

Advantages of acrylic laser cutting

Due to its properties, laser cutting of acrylic has a number of advantages over other methods:

  • Cutting quality. After laser cutting of acrylic, the edge of the material turns out to be transparent, clean and smooth;
  • High cutting speed. Compared with traditional methods, laser cutting of acrylic is several times faster;
  • The accuracy of laser cutting of acrylic is 0.03 mm. This allows you to perform work with high tolerance requirements, reduces material overruns during laser cutting of acrylic, since a thin laser beam does not affect the material adjacent to the cutting line.;
  • The CNC allows you to keep tolerances, perform laser cutting of acrylic along complex trajectories, reduces the reject rate to zero and guarantees the repeatability of the cut products;
  • Non-contact exposure. During laser cutting of acrylic, the material is not damaged, since it does not need to be fixed and there is no mechanical impact of the cutting tool;
  • Cutting tool. The laser is not blunt and the acrylic does not stick to it, unlike mechanical cutting methods;
  • Service life. The life of the laser tube depends on the manufacturer and can reach 10,000 hours. This is 4.7 years of work, if you count the standard 8-hour shift 5 days a week;
  • No chips and dust. The laser gently and cleanly melts acrylic, without creating byproducts of laser cutting of acrylic;
  • Low noise level. The laser has no physical contact with the material, so the laser cutting of acrylic is quiet;
  • Easy to master. You can learn the basic principles of working on an acrylic laser machine in a few hours;
  • Multipurposeness. The acrylic laser machine also works with other materials: any type of wood materials, various plastics, textiles and leather. The acrylic laser machine can not only cut, but also engrave;

What can be done with the help of an acrylic laser cutting machine

Today it is difficult to imagine a person who would not meet with products made with the help of laser cutting of acrylic on a daily basis. Judge for yourself, they are made of acrylic:

  • Interior and exterior decor;
  • Souvenir products;
  • Elements of outdoor advertising;
  • POS products;
  • Elements of architecture;
  • Building elements;
  • Lighting equipment;
  • Cases, panels, dials and other elements of devices;
  • Storage tanks;
  • Aquariums and terrariums;
  • Other products.

What kind of acrylic is there and what are the differences between different types of acrylic?

Types of Acrylics

In color, acrylic is not only transparent, with the use of special dyes in production, a colored, mirror or translucent material is also obtained.

According to the production method, there are two types of acrylic: extrusion and injection molding. Each type has its own properties. 

Extruded acrylic for laser cutting

Extrusion acrylic is obtained when an acrylic mass is fed through an extruder under pressure. The slot of the extruder, and hence the thickness of the material, can be from 1 to 24 mm.


  • Small divergence in sheet thickness (up to 5%);
  • Any length up to 4 meters;
  • Requires less power for laser cutting acrylic;
  • The price is lower than that of molded acrylic;
  • Requires less effort for vacuum forming, makes products of complex shapes better.


  • Thickness from 1 to 24 mm;
  • Residual stress and weak molecular bonds;
  • Fragility of the material;
  • The engraving is obtained with a gray tint;
  • Not suitable for vacuum reshaping.

Molded acrylic for laser cutting

Injection-molded acrylic is obtained when a liquid acrylic mass is poured between two sheets of glass under pressure. 


  • Almost any thickness;
  • Strong molecular bonds, no residual stress;
  • Higher impact resistance compared to extrusion acrylic;
  • Surpasses extrusion acrylic in light transmittance;
  • The engraving turns out to be perfectly white;
  • Allows vacuum reshaping of the product.


  • The dimensions are strictly limited in length and width;
  • The price is higher than that of extrusion acrylic;
  • The divergence in sheet thickness is up to 30%, which complicates the production of prefabricated elements;
  • Vacuum forming requires more effort compared to extrusion acrylic.
After laser cutting of acrylic, special bending machines are used to give the necessary shape.

For laser cutting of acrylic, injection-molded acrylic is more advantageous, since the extrusion one often cracks due to residual stress.

To what thickness is laser cutting of acrylic possible

One of the most frequent questions when buying an acrylic laser machine is to what maximum thickness is laser cutting of acrylic possible?

Laser machines on acrylic confidently cut material with a thickness of 20 mm. At the same time, you can make laser cutting of acrylic with a thickness of 25 mm, but in this case you will have to put up with a low speed of work and, most importantly, a clear taper of the edge will appear.

Acrylic Engraving

We should also focus on engraving, since this feature is an undeniable advantage for an acrylic laser machine compared to other methods of cutting acrylic.

Laser engraving of acrylic allows you to significantly expand the production capabilities. With the help of an acrylic laser machine, you can cut out products and immediately put the necessary information on them in the form of inscriptions or images.
