Laser Cut & Engraving Acrylic

October 12, 2022


I believe you are already very familiar with acrylic sheet. It is a replacement product for plexiglass, and in our lives, we will often see acrylic products. So, why do people like acrylic sheet so much? First of all, let’s understand the advantages of acrylic panels.

  1. acrylic sheet light transmission is particularly good, its light transmission rate can reach 92%.
  2. Second, the corrosion resistance of acrylic panels is also very outstanding. In the changing outdoor environment, acrylic panels can withstand the test of wind, sun and rain.
  3. We can process the acrylic sheet into any shape we like.
    If you are also interested in acrylic sheet, then let’s explore the wonderful world of acrylic sheet together.

Acrylic panels have the advantages of waterproof, moisture-proof, UV-proof, corrosion-resistant, high light transmission rate with a crystal texture. The city can be seen everywhere in the road signs, advertising light boxes and other more acrylic material.

III. How to laser cut acrylic

Common problems of cutting acrylic sheet

  • The acrylic cutting surface is not flat,
  • There are many bumps
  • Serious reflection of honeycomb panel
  • Cut edge whitish

So how do we solve this problem? Thunderlaser has summarized some very useful methods in repeated practice.

Laser cutting acrylic settings

  1. POWER: Power settings are 65% and 70%. Laser cutters cut straight lines faster than corners.
  2. SPEED: The cutting speed is set to 1mm/s-10mm/s. As we all know, the faster the cutting speed, the higher the work efficiency. When we are cutting general materials, we will increase the power and increase the speed. But acrylic sheet is different from other materials. Cutting too fast will result in an uneven cut surface. There is a bumpy feeling. In order to cut out a smooth effect, in the parameter design, increase the power and reduce the speed.
  3. Air Assist:Do not blow air when cutting. Using blowing air during cutting will cause the cut surface of the acrylic sheet to become white.
    However, there is one more issue to be aware of. When using the acrylic sheet without blowing air, be sure to observe it at all times, because there is no flame retardant with strong air blowing, and the cut material is easy to catch fire. This would be very dangerous.
  4. Prevention of laser reflection from honeycomb panels: The last point is to avoid the reflection of the honeycomb panel, which leads to the phenomenon of edge fusion. However, we also have a solution to this problem.

Cutting parameters:

  • Whether to blow air: no
  • Speed: 1mm/s-10mm/s
  • Power: 65%-70%

How to set parameters for cutting acrylic sheets

The most important point of cutting alive engraved acrylic sheet is to set the parameters of the machine. Only the appropriate cutting parameters can cut out the perfect acrylic crafts.

1. Can a 40W laser cut acrylic?

A 40-watt laser cutter can cut acrylic sheets. But the thickness of the acrylic sheet cannot exceed 5 mm. The cutter speed was set to 1 mm per second. Only the slower the cutting speed, the smoother the cut can be.

2.How to Engrave Photos on Acrylic Sheets

First we use ps to convert the color photo to grayscale image. The second step is to convert the grayscale photo to bitmap format. Finally, flip our image upside down. Put the acrylic plate on the laser engraving machine and set the speed to 500mm/s.
