Laser engraveable plastic comes in many different colors, thickness, coatings, and surface textures.
Most engravers plastic will engrave and cut well with the laser system as long as it is microsurfaced and
formulated for laser engraving. Removal of large amounts of material will warp the plastic. You might
need to tape it down or hold it down flat somehow to prevent it from curling as you engrave. Since these
plastics have low melting point, a low PPI setting is used when cutting to reduce the possibility of melting.
Masking and dampening with water also helps to reduce melting and keeps the plastic clear of smoke
residue. Always remove the original clear masking from the plastic because it does not react well with the
laser. Since there are so many types of engravers plastics, the only true way to find out if a particular
brand and type will work well with the laser is to experiment. Use these power settings as a guideline for
experimentation and adjust as necessary. Thicker top coated plastics are not recommended because it
requires too much power to remove the material and the large amount of smoke created usually stains
the substrate.
LASER ENGRAVING OR CUTTING PLASTIC CAN IGNITE THE
MATERIAL. Never leave the laser system running unattended for any
reason.
