Feature: 1. Strong Scalability \u0026 Compatibility - Standardized structure and drive interface can be adapted to various 3D printers, such as Ender-3 S1/Ender-3 S1 Pro/Ender-3 S1 Plus, laser engraving machine, CNC engraving machine and other machines according to requirements. 2. Safety conservation - A special laser safety shield is adopted to meet the FDA Class 4 safety requirements to avoid laser damage to eyes and skin. 3. Convenient to install - Take out laser head kit and a cylindrical head thumb screw from the packing box. Install laser head kit on the fixing plate. Tighten it with cylindrical head thumb screw (clockwise) 4. Pollution minimization - Built-in air filter cotton can effectively absorb smoke and odor generated by engraving. Reduce indoor air pollution and care for human health. 5. Thin Laser Spot and Long Service Time - Imported laser semiconductor diode, stable power, fine spot, long service life, sustainable use of 10000+ hours. Support carving or cutting material such as cardboard, wood, bamboo, rubber, leather, fabric, acrylic, plastic, etc. Specification: Features: Strong Scalability & Compatibility - Standardized structure and drive interface can be adapted to various 3D printers, such as Ender-3 S1/Ender-3 S1 Pro/Ender-3 S1 Plus, laser engraving machine, CNC engraving machine and other machines according to requirements.
