Acrylic works great for this, we've done both however. For glass we send a CAD file to a local glass company that cuts it for us then we print the pieces. For acrylic we reverse print and router it. You can flame the edges and it looks like glass (we just use a small propane torch like used for wraps). Do a test piece because it can be a bit of an art. If you do flame the edges do not clean it with alcohol as it will spider crack like crazy.
