would be surprised in the plastic is lexan if it has a polished edge as lexan is a brand name for polycarbonate and this stuff is toxic to cut and flame polish.
acrylic is not good for plastic but the best compromise between the 2 is pteg as can be laser cut, clear finish, flame polish and tougher than acrylic and closer to polycarbonate.
most pinball plastics and ramps is made from pteg.
sorry I did not see the thread earlier, hope that helps
