Strength/Stiffness of Acrylic

post #1 of 9
Thread Starter 
I am doing the research for my new case project and I am thinking of using a lot of acrylic. I have never used it before so it should be a whole lot of fun One thing I am wondering is how strong/stiff are the 1/8 " sheets of acrylic?

Lexan or polycarbonate plastic is the best, far stronger and more workable than plexi. Plexiglass is far more likely to crack when cut or drilled.

Cracks pretty easy. Be sure to use caution. The thing is that the acrylic melts and clogs your bit and then it is just heat that is cutting it and it gets sloppy. I have a friend with a CNC machine and we have cut 1/8 lexan but we avoid acrylic if we can. I will try to take a picture next time I go over to his house.

Polycarbonate is awesome. Really easy to work with and stronger.

hmmm one of the reasons I was wanting to go with acrylic is because it is reasonable easy to shape once its heated up and of course all the cool transparent colors you can get it in.

Still all good info but now I am going to maybe need to rethink my plan.

Lexan can be formed with heat but its far more demanding. Aprox 300f to work it.

Well I revised my design idea so shaping is not an issue but I am searching and the Lexan I am finding is coming in sizes that is going to leave me a lot of excess.

Still leaning towards acrylic. I think I am going to hunt up some small or scrap pieces to play with so I can get a better idea of what working with it is going to be like.
