Acrylic is also know by the chemical name poly (methyl methacrylate). There are two basic types of acrylic: cast and extruded. Cast acrylic is made by casting the poly (methyl methacrylate) resin into a mold or onto a moving steel belt to form sheets. Cast acrylic is ideal for laser engraving because it creates a frosted surface. Laser Cutting Acrylic Although extruded acrylic has limited color selection (clear, opal and black) cutting extruded is much cleaner than cast. The laser vaporizes through extruded more easily leaving a smooth, almost glass-like, flame polished edge. Its also cheaper than cast.

Material properties. Polypropylene Sheet, Copolymer – Propylex® is a flexible, tough material that is easy to fabricate with. When laser cutting polypropylene, the cut width (the amount the laser takes away when cutting) is generally slightly thicker than on acrylic which is worth baring in mind if cutting very complicated artwork.
