Nylon is a generic name referring to a series of thermoplastic aliphatic polyamides. Some common formulations are nylon-6 and nylon-6,6. Laser processing of nylon can be performed with a 9.3 or 10.6 micron CO₂ laser. Nylon does not readily absorb the energy from the 1.06 micron fiber laser and is not recommended for this material. Laser cutting of nylon with a CO₂ laser produces a clean edge with minimal melting along the cut path. Laser engraving of nylon is also possible with a CO₂ laser and results in a clean mark with limited melt-back at the point of ablation.
