The laser module features 30W power input, 7.5W optical power output,  445nm~450nm wavelength, TTL modulation, vision protection, modified laser air assist and high-speed cooling fan. Great for cutting and engraving various soft materials.

Features:
– Designed for laser engraver, laser cutter, 3D printer(which supports laser engraving), CNC machine, replacement for Arduino project and NEJE Master series.
– TTL modulation supports variable power input from 3.3V to 12V.
– Wide compatibility. Designed with 3 interfaces: DC12V+TTL, 3Pin 2.54 interface, and 3pin interface.
– 7.5W blue light diode laser, 30W module input, suitable for engraving and cutting.
– Fixed lens design, not focusing lens, change the object height to change the focus distance.
– Protective glass for more safer and comfortable operation, no need to wear goggles.
– Modified laser air assist, avoid smoke damage to the lens, keep the optical power stable.
– Quiet and intelligent drive adjusts the cooling fan speed according to the laser temperature.
– 15000 rpm high speed cooling fan for more effective heat dissipation.
– Built with heat-removing silicone grease for strict control of temperature.
– Engrave a wide range of soft materials: MDF/Balsa/Paper/Wood/Fabric/Plastic/Leather/Plywood/Foam Paper/Anodized Aluminum. 

Note:
*For 3D printer, this module only works for the one that supports laser engraving.
