Longer Laser B1 20W Laser Engraving Machine 4-core Laser Head 22-24W Output Power 450 x 440mm Engraving Area

• 20-24W Ultra-high Power Laser: With the most advanced six-core laser technology, Laser B1 20W has a strong 20-24W optical output power, one of the most strongest available diode-laser today and thus a much stronger cutting ability. Laser B1 20W can cut through 15mm Pine, 8mm black acrylic, and even 0.1mm stainless steel in one-pass, 20mm basswood and 35mm black acrylic in multi-passes.
• Highly Concentrated Laser and Stronger Cutting: With the most cutting edge laser coupling technology, Laser B1 20W has a thinner and longer focal length(50mm), yet stronger laser beam, which increase the cutting capability 20%+ stronger comparing to other 20W lasers. It can cut through 20mm basswood and 35mm black acrylic by multi-passes.
• Bigger Working Frame: 17.72x17.32 inches/450x440mm working area, Laser B1 20W provides a 23.75% increase in working size comparing to others, which meets the demands of most scenarios, especially ideal for A3 panels. 
• 36,000mm/min High Speed: Laser B1  is equipped with a new 32-bit motherboard, which allows engraving speed up to 36,000mm/min, four times faster than ordinary laser engraving machines. In addition, TMC2209 silent drivers 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.
• Eight Major Safety Protections: Eight 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 20-24W laser 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.
• Sturdy Metal Frame: Laser B1 is made with an aluminum frame with improved mechanical designs and is very stable even under high-speed working mode. This helps to make better engraving and cutting arts. 
• Focus Positioning Bar: The laser module integrates a pull-down focus bar, which is easy to use, just pull down the focus bar, and move the bar towards the surface of the working panel.
• XY-axis Limit Switches: Added X-axis and Y-axis limit switches can accurately locate the position of the laser module. At the same time, if the laser module moves in the negative direction of the X-axis or Y-axis, Laser B1 will trigger an alarm and stop the movement.
• Laser Lens Protection: Laser module is equipped with a replaceable protective lens, which effectively prevents the smoke from polluting the laser lens, and greatly improve the service life of laser module.
• Multiple Data Transfer Options: Data can be transferred via different methods of Wi-Fi, USB cable, APP and TF cards , which supports offline operations. You can use anywhere, without the limits of physical connection to a computer.
• Great Software Support: Laser B1 is compatible with various mature carving software, such as LaserGRBL and LightBurn. It supports Windows 7+, macOS, Linux; engraving file formats Support JPG, PNG, BMP, G- code, GIF, SVG, NC, GC, etc.
