Cast Vs Extruded Acrylic Laser

In addition cast acrylic when laser cut produce a highly polished edge thus reducing finishing times when fabricating. Extruded acrylic sheets generally have a better thickness tolerance due to the manufacturing process. Furthermore when hot wire line bending drape or vacuum forming cast acrylic sheets are more malleable pliable than extruded acrylic sheet.
