Acrylic sheet is a familiar material in daily life and is widely used as an alternative to plexiglass. From signs and display products to decorative crafts and custom logos, acrylic products appear everywhere because the material is clear, durable, and easy to shape.

Acrylic panels offer several advantages for laser processing. They have strong corrosion resistance, can withstand outdoor exposure to wind, sun, and rain, and provide excellent light transmission of up to 92%. Acrylic sheets can also be processed into many different shapes, making them suitable for creative and commercial projects.

1. Acrylic Laser Cutting and Engraving Ideas

Acrylic panels are waterproof, moisture-proof, UV-resistant, corrosion-resistant, and highly transparent. Their crystal-like appearance makes them popular for road signs, advertising light boxes, logos, display panels, maps, models, and many other laser-cut or laser-engraved projects.

2. Laser Machines for Acrylic

The right acrylic laser machine depends on your working size, cutting thickness, engraving needs, and production workflow. For smaller acrylic panels, a compact CO2 laser cutter can be a practical choice. For fast acrylic engraving, an RF CO2 laser engraver can help improve efficiency.

2.1 Small Acrylic Laser Cutting Machine

If you do not need to process large acrylic panels, a smaller acrylic laser cutting machine can be a suitable choice. The Nova laser cutting machine is designed for acrylic panel cutting and offers multiple work area and power options.

2.2 Acrylic Laser Engraving Machine

An acrylic laser engraving machine can create clean and detailed acrylic crafts. The Bolt Pro can reach an engraving speed of 2000 mm/s, helping improve work efficiency for acrylic engraving projects.

3. How to Laser Cut Acrylic

3.1 Common Problems When Cutting Acrylic Sheet

During acrylic laser cutting, several common problems may appear if the settings or workholding are not suitable:

• The acrylic cutting surface is not flat.
• There are many bumps on the cut edge.
• The honeycomb panel causes serious reflection.
• The cut edge turns whitish.

These problems can often be improved by adjusting power, speed, air assist, and the way the acrylic sheet is supported during cutting.

3.2 Laser Cutting Acrylic Settings

• Power: Power settings are 65% and 70%. Laser cutters usually cut straight lines faster than corners, so power must support both straight and corner sections.
• Speed: The cutting speed is set to 1 mm/s–10 mm/s. Acrylic differs from many other materials because cutting too fast can create an uneven surface and a bumpy edge. To achieve a smoother result, increase power and reduce speed.
• Air assist: Do not blow air when cutting acrylic. Blowing air during cutting can cause the cut surface to turn white. However, when cutting acrylic without air assist, always monitor the material closely because the material may catch fire without strong airflow.
• Honeycomb reflection prevention: Avoid honeycomb panel reflection, as it can cause edge melting and affect the finish of the acrylic cut.

4. How to Set Parameters for Cutting Acrylic Sheets

The most important step in cutting or engraving acrylic sheet is setting the machine parameters correctly. Suitable parameters help create clean, clear, and precise acrylic crafts.
