How to Use a Laser Cutting Machine to Cut Acrylic Plates and Achieve a High-Clear, Shiny Edge Finish**
Laser cutting is an ideal method for cutting acrylic, offering high precision and clean, smooth edges. One of the key benefits of using a laser cutting machine is its ability to cut acrylic with minimal burrs or roughness, leaving you with edges that can be polished to a glossy, high-clear finish. By Mintech laser cutting machine, you could cut up to 1.5-inch-thick acrylic only one process and no need to polish again. Follow this guide to learn how to cut acrylic using MINTECH laser cutting machine, and achieve a professional, shiny result.
Materials Needed:
- Laser Cutting Machine
- Acrylic sheet (clear, colored, or frosted, depending on your project)
- Laser cutting software (compatible with your machine)
- Safety equipment (gloves, safety glasses)
- Acrylic cleaner and microfiber cloth
Step 1: Prepare the Acrylic Sheet
Before using the laser cutting machine, make sure the acrylic sheet is ready for cutting.
- Clean the Acrylic: Use a microfiber cloth to wipe down the acrylic sheet, removing any dust, dirt, or fingerprints. Cleaning the surface ensures you’re cutting on a clean material, which helps achieve a smoother finish.
- Measure and Mark: Measure the dimensions of the acrylic plateand mark where you want to cut. If needed, use a ruler and a fine marker to indicate the cutting lines clearly on the material.
- Secure the Acrylic Sheet: Place the acrylic sheeton thelaser cutting machine’s worktable. Ensure that it is properly aligned with the machine’s axis and is secured in place.

Step 2: Set Up the Laser Cutting Machine
Now it’s time to set up the laser cutting machine for your project.
- Choose the Right Laser CuttingSettings: Set the appropriate laser power, cutting speed, and frequency based on the thickness and type of acrylic you're cutting. For thicker acrylic (e.g., 10mm or above), you’ll need higher power settings. Thin acrylic sheets (e.g., 3mm) require lower power settings to avoid excessive melting or burning.
- Tip: Start with a low power setting and increase it if necessary to avoid burning or scorching the edges.
- Choose the Right Focus: Ensure the laser is properly focused for optimal cutting. The focus should be adjusted according to the thickness of the acrylic to ensure a clean cut without excessive heat distortion.
- Set the Cutting Path: Import the design file into the laser cutting software and adjust the cutting path. Ensure that the lines for cutting are set to a “cut” mode, while engraving or etching areas are set to “engrave” or “mark” mode (if applicable).
- Run a Test Cut: Before starting the main job, it's always a good idea to run a test cut on a small scrap piece of acrylic. This will ensure that the settings are correct and that you get the desired edge quality.

Step 3: Cutting the Acrylic Plate
Once the laser cutting machine is set up and the test cut has been verified, it's time to cut the acrylic.
Start the Cutting Process: Press the start button to begin the cutting process. The Laser Cutter will follow the programmed paths, cutting through the acrylic sheet precisely.
Monitor the Cut: Keep an eye on the process, especially during the first few minutes, to ensure there are no issues such as excessive fumes, smearing, or burning. Acrylic tends to generate fumes when cut, so ensure adequate ventilation or use a fume extraction system.
Check for Smoothness: Once the cut is complete, inspect the edges of the acrylic. The edges should be smooth and clean, with minimal burrs or imperfections.
Step 4: Achieving a High-Clear, Shiny Edge Finish
After the acrylic plate is cut, you can further enhance the edges to achieve a high-clear, shiny finish. Here’s how:
Inspect the Cut Edges: Laser cutting typically produces a smooth edge, but some minor residue or slight haze may remain, especially with thicker acrylic. Check the edges for any roughness or discoloration.
Step 5: Final Inspection and Display
- Inspect the Finished Edges: After polishing, inspect the acrylic edges under good lighting to ensure they are free from imperfections and have a glossy finish.
- Clean the Surface: Clean the entire acrylic piece with a soft microfiber cloth to remove any dust or fingerprints, ensuring that your final piece looks professional.
- Display or Assemble: If your acrylic piece is part of a larger craft, sign, or display, assemble it accordingly. If you plan to mount or frame it, be mindful of how the edges will be viewed to maintain that high-clear finish.
Tips for Achieving the Best Results:
- Ventilation: Ensure that the cutting area is well-ventilated or has an exhaust system to remove the fumes generated during the laser cutting process.
- Laser Power Settings: If you’re cutting thicker acrylic, you may need to adjust the laser power and cutting speed accordingly to prevent melting or burning.
- Focus the Laser: Always ensure the laser is properly focused for the material’s thickness to ensure a clean, sharp cut with minimal heat distortion.
Conclusion
Using a laser cutting machine to cut acrylic plates is a precise and efficient way to create clean, intricate designs. By properly setting up your machine, selecting the right settings, and applying the correct finishing techniques, you can achieve a high-clear, shiny edge that enhances the appearance of your acrylic crafts. Whether you’re making custom signs, decorative pieces, or functional items, a laser-cut acrylic piece with a polished edge offers a professional and polished look.
