I am trying to find out if you can use the flex cuts on acrylic and have it able to roll up without breaking, basically turning it into a mat. I am also curious if this is possible with wood. This would be something that would be rolled up and unrolled a lot. If anyone knows how Flex works exactly would greatly appreciate an explanation so I know what I need to make the cuts.
Are you referring to what is sometimes called a ‘living hinge’? I know that it can be done with wood, but I’ve not personally ever seen anyone do it with acrylic. Somehow, I don’t think acrylic could withstand repeated rolling and unrolling.
Try a search for living hinge first…
As stated here and elsewhere, regular acrylic will not withstand this. Even plywood won’t tolerate repeated flexing. The “living hinge” permits a rounded shape to be made, but it won’t work as an actual hinge.
Acrylic is notoriously brittle - so no, even with living hinge cuts it won’t roll like a mat repeatedly without breaking. Polypropylene will, but it doesn’t even need living hinge cuts to do so.
As for wood - it depends on the wood, the living hinge pattern and how tightly you roll it. I’ve had a book shaped lamp for years that still looks new but I’ve also made things that cracked on first assembly.
As noted even wood will not take that much bending before breaking, however., as it is frequently seen a line of sticks bonded to a flexible material might be a different matter. In addition at 300 degrees F (or thereabouts), acrylic will flex like rubber but get hard again as it cools.
A stack of sticks with a line of extra strong clear tape, or a similar flexible material held with a solvent glue at each end might do the trick for you, even if the tape needs to be replaced occasionally.
