Thank you for purchasing your Universal Eco Saver PLH3D-6W-XF+ Engraving and Cutting Laser Upgrade Kit.

This sub-assembly contains a high-power cutting and engraving laser with thermal protection and a professional high-speed driver. Its design ensures that the engraving laser does not require any additional cooling. The fan and airflow design make it perform as a fully customized air nozzle, protecting the lens from dirt while cooling the cutting laser. Each PLH3D laser product utilizes a dedicated driver which ensures the proper function of the cutting laser and protects its three laser diodes from overheating. There is an automatic thermal cutoff where at 45°C the cutting laser switches off. 

This cutting laser allows you to cut or engrave materials such as rubber, wood, leather, plastics, paper and card stock among other choices. With a fully analog power modulation, it is possible to engrave in shades of gray or change the output power between consecutive runs. The same effect can be achieved with a PWM signal which is fully compatible with PLH3D drivers. High power modulation (up to 100 kHz) ensures the high speed of the cutting laser, even for the most sophisticated patterns.

This cutting laser utilizes one (in case of PLH3D-6W) or three (in case of PLH3D-15W) NUBM44 450 nm diodes, which are the strongest available blue laser diodes on the market. The lifetime of NUBM44 450 nm laser diode stands at 10 000 hours as given by the manufacturer.
