How to cut acrylic light diffuser panels


My diffuser was way to brittle, my patience way to short, and my tool-set way too small to perform most of the suggestions already posted.

I was able to heat a blade (box cutter) with a small torch (a big torch lighter); making quick work of cutting along a line.
I metal strait edge below the diffuser helps keep the line strait.

You'll have to develop your cut-and-heat technique as you go.
I went between heating the mid-point of the blade, and plunging the blade into the line; cutting an inch with each plunge (every 3 or 4 seconds).

Edges weren't perfect, yet good enough for my purposes.

Cheers.

How to cut acrylic light diffuser panels


Examine the edges of the factory-cut panels. They appear to have been melted. Observing this, I went to Amazon and bought a 25-watt, hot-knife (an electric soldering iron with an X-Acto style knife tip). When the knife is hot, I score on the textured side of the panel through the texture but not all the way through the panel. When the score line cools, I snap it as I would with any other scoring tool. The melted edges of the score line keeps cracks from propagating into the panel, unlike the cold scoring methods. The hot knife is cheap and can be used as a soldering iron/wood-burner. PS: I bought the Walnut Hollow Professional Hot Knife sold by SuperMart on Amazon for $15, free shipping. It comes with two X-Acto knife style blades. The Walnut Hollow Creative Hobby Tool comes with a variety of tips for cutting, soldering and wood burning.

I use an angle grinder with a metal cutting blade to pretty much melt through the lens

I cut this stuff all the time with a table saw. If you have a good sharp fine tooth blade and take your time there are no issues.

No fine tooth available?
reverse the blade

How to cut acrylic light diffuser panels


I tried cutting acrylic sheets once using the scoring method. I failed. My sheet was too long it was hard having to score many times to get a clean snap.

I then tried a jig saw using a 32tpi blade and slow speed. That was easy. I didn't get any edge melting or cracking. The edge was smooth - much much smoother than the factory edge.
