Features: 【33-36W Ultra-high Power Laser】With the most advanced 6-core laser technology, Laser B1 30W has a strong 33-36W optical output power, one of the strongest available diode-laser today and thus a much stronger cutting ability. Laser B1 can cut through 20mm paulownia wood, 10mm black acrylic, and even 0.1mm stainless steel in one-pass, 25mm basswood and 50mm black acrylic in multi-passes. 【Bigger Working Frame】17.72x17.32 inches/450x440mm working area, Laser B1 30W provides a 23.75% increase in working size comparing to others, which meets the demands of most scenarios, especially ideal for A3 panels. 【 High Speed Engraving Machine】Laser B1 is equipped with a new 32bit motherboard, which allows engraving speed up to 36,000mm/min, 4 times faster than ordinary laser engraving machines. In addition, TMC2209 silent driver is used to effectively reduce the noise of operation, providing a faster and more enjoyable experience. 【Smart Air-Assist System】Air assist pump can be automatically turned on/off. This is controlled directly by the lightburn, based on the parameters set in the program, which greatly enhances cutting ability and also significantly improves cutting precision and quality. 【Multi-Color Engraving】The high-energy laser beam instantly oxidizes the metal surface, bringing 300+ rich colors to fulfill your colorful creative needs. 【8 Major Safety Protections】8 safety protection features are installed, i.e. Move/ Flame/Offline/Motionless/Security Lock/Eye Protection/Emergency Stop Button/Zero Reset. Laser automatically shuts down when falling, flame, data disconnection and laser head freezing over 15 seconds are detected. In addition, laser head is automatically reset to zero to avoid burnout when fire. And the panoramic filter glass can effectively filter 99.8% of the laser, safer to use. 【Engraving up to 1000+ Materials】With 33 - 36Wlaser power and its strong cutting and engraving capacities, Laser B1 can cut or engrave up to 1000+ materials, such as wood, stainless steel, leather, silver, acrylic, cloth and more.
