The Dangers of Cutting an Acrylic Sheet With a Table Saw

Combustion

• Acrylic is a type of material known as a combustible thermoplastic, and it is often referred to by brand names such as Plexiglas or Lucite. Cutting these sheets with an ordinary table saw might result in a fire or explosion. The problems occur when you cut the sheets near other flammable materials. The table saw might release some sparks as the blade cuts through the plastic, which in turn causes the combustion of the material. As the fire spreads, it can lead to an explosion. When cutting through the acrylic sheets, keep the sheets away from any flammable or combustible materials.

Uneven Cuts

• Cutting through the acrylic with a table saw comes with the risk of uneven cutting. The table saw slowly pushes through the sheets, removing the excess material. If your hand slips just once, you might leave behind a jagged line or an uneven cut. The best way to reduce the problem is to measure and mark your line, but check the line at least twice. Use a level, which ensures that the line is completely level. You can also use a metal square, such as those used by architects or professional designers. Cut along the metal square, which keeps your cutting on track.

Personal Injury

• Anytime you use a power tool, you put yourself at risk of personal injury. Cutting through acrylic is even more dangerous because of the coating on the top and bottom of the sheets. The coating makes the sheets slightly stick, which makes it difficult to hold onto the sheets. As your hands slip across the coating, you risk cutting yourself or even losing a finger or limb.

Using the Wrong Blade

• When cutting acrylic, you must use the proper type of blade for your particular project. A circular saw makes straight cuts, but a band saw makes larger cuts through thicker sheets and is suitable for creating curved cuts or designs. Using the wrong type of saw might result in shattering the acrylic. You also risk leaving behind a jagged edge by cutting through thicker sheets with the wrong blade.
