Polystyrene, also known as PS or styrene, is a thermoplastic and is part of the vinyl polymer family. Laser processing of polystyrene can be performed with a 10.6 or 9.3 micron CO2 laser. Laser cutting of polystyrene can be performed with a 9.3 or 10.6 micron CO2 laser, resulting a clean, smooth, slightly melted cut edge, free of discoloration. Laser engraving of polystyrene can be performed with a 9.3 or 10.6 micron CO2 laser and results in depth with a smooth slightly melted surface. Laser marking of polystyrene with a CO2 laser is not recommended as a contrasting mark is not created. The 1.06 micron fiber laser wavelength is not readily absorbed by polystyrene and is not recommended for use with this material.
