From Scoring to Sawing: Step-by-Step Instructions for Cutting Polycarbonate Sheets

Polycarbonate sheets, hailed for their combination of strength, clarity, and flexibility, have become an integral material in various applications. Yet, when it comes to customizing these sheets for specific needs, cutting them accurately is crucial. Here’s a step-by-step guide to help you achieve a clean and precise cut, whether you’re working on a DIY project or a professional assignment.

Materials You’ll Need:

  • Polycarbonate sheet
  • Tape measure or ruler
  • Marking pen
  • Utility knife (for scoring method)
  • Circular saw or jigsaw (for sawing method)
  • Clamps
  • Fine-tooth blade (with at least 10 teeth per inch)
  • Safety goggles
  • Dust mask
  • Sandpaper (optional)

1. Safety First: Before beginning any cutting process, ensure you are wearing safety goggles to protect your eyes from any flying debris. If you’re sawing, wearing a dust mask is also advisable to prevent polycarbonate laser cutting  of fine plastic particles.

2. Measure and Mark: Using your tape measure or ruler, measure the desired size of your cut. Mark the measurements clearly on the polycarbonate sheet using a marking pen.

3. Choose Your Cutting Method:

There are primarily two methods to cut polycarbonate sheets:

a. Scoring Method (For Thin Sheets):

  1. Place the sheet on a stable surface, ensuring the portion to be cut off hangs slightly off the edge.
  2. Using a utility knife, firmly score along the marked line multiple times.
  3. Hold the sheet securely and apply a quick, downward force on the hanging portion. The sheet should snap cleanly along the scored line.
  4. If any edges are rough, you can smoothen them using sandpaper.

b. Sawing Method (For Thicker Sheets):

  1. Secure the polycarbonate sheet using clamps, ensuring the cutting line is slightly overhanging to minimize vibrations.
  2. Install a fine-tooth blade on your circular saw or jigsaw. This blade ensures a smoother cut and reduces the risk of chipping.
  3. Begin sawing at one end of the marked line and progress steadily, letting the blade do the work without applying excessive force.
  4. Once cut, if there are rough or uneven edges, they can be smoothed out using sandpaper.

4. Post-Cutting Clean-Up: After cutting, ensure you clear away any plastic debris or shavings. If you’ve used the sawing method, it’s also advisable to clean the sheet with a soft cloth to remove any plastic dust.


Cutting polycarbonate sheets can be straightforward when you’re equipped with the right tools and knowledge. By following these step-by-step instructions, you’ll achieve clean, precise cuts, ensuring your project’s success. Always prioritize safety and take your time, especially if you’re new to the process. With practice, cutting polycarbonate will become second nature.
