Plexiglass, also known as acrylic glass, is a versatile and long-lasting material used for a variety of projects, including picture frames, windows, shelves and crafts. Plexiglass is lighter, cheaper, and more shatter-resistant than glass. However, cutting plexiglass requires a delicate hand to achieve clean, precise cuts without damaging the material. In this article, we will walk you through the step-by-step process of cutting plexiglass effectively and safely.

Procedure
Measure and mark the Plexiglass
Place the plexiglass sheet on a clean, flat surface and secure it using clamps. Check that the surface is stable and free of sharp objects. Make sure that the glass is secured and won’t move during the cutting process. Do not remove the plastic sheet from the plexiglass to avoid scratches. Remove it carefully once you are done with the cutting process.
Using a measuring tape, measure the dimensions you want to cut on the plexiglass sheet. Mark the measurements using a pencil or marker, ensuring that the lines are clear and visible. Mark the measurements directly on the protective sheet of the plexiglass. Double-check your measurements to ensure accuracy. Â
Cut the glass
Use a plexiglass cutter, align it with the marked line and apply firm, uniform pressure while dragging it along the line. For some sheets, you may be required to run the blade over the line several times until you create a deep groove in the sheet. Flip the sheet over and run the cutter along the same line. This will make the sheet weaker and more prone to breaking along the line.
Once you are done with the cutting process, carefully lift the plexiglass from one end and apply downward pressure to snap it along the scoreline. The sheet should snap along the scored line. If you are facing problems, cut along the line one more time.
Smooth out the edges
To achieve a smooth finish, you need to smooth out the rough edges. Use a sandpaper or a sandblock and gently sand down the glass to remove any rough or sharp edges. Be careful not to scratch the surface of the sheet.Â
