Scroll saws are very versatile tools that can cut through many materials, including wood, metal, and most types of plastics, including acrylic. To do so, you’ll want a blade that’s designed for cutting plastic. One such blade is a crown-tooth blade.  The trick to cutting acrylic successfully, however, is to prevent the buildup of heat. Because the saw blades generate a lot of friction, it’s very common for the acrylic to melt slightly and then reseal just a few seconds later, leaving you with uneven cut lines or even shattered acrylic. To avoid this, direct a fan towards your workbench while you cut, do not remove any protective backing paper from the acrylic until after it’s cut, set your saw to the lowest speed that still cuts effectively, and lubricate the saw blade before starting to make the cut.
