Laser Marking PLA contains a laser-sensitive additive optimized to work within a 980 – 1064 nm wavelength. The material has been tested successfully with a Nd:YAG- and fiber lasers, and it does not work with CO2 lasers. A proper laser is required for marking the 3D print.
Laser marking has various advantages over conventional marking technologies:
– The markings are permanent, waterproof, wear and heat resistant, lightfast and resistant to chemicals.
– Flexibility in marking design.
– No pre- or post-treatment is required.
