It can cut through 15mm paulownia wood, 8mm black acrylic, and even 0.05mm stainless steel in one pass. Multi-passes can also be done on 25mm basswood and 35mm black acrylic.

Bigger Working Frame

The larger working frame of the LONGER B1 20W Laser Engraver is a significant advantage over other machines in the market.

This larger working area allows you to engrave or cut larger materials, which is particularly useful for those who work with larger pieces of wood, leather, acrylic, or other materials. With this increased working area, you can create more intricate designs, add more details to your projects, and work on larger pieces without having to worry about running out of space. Overall, the LONGER B1's larger working frame is a significant advantage for those who need more space to work with and want to take their projects to the next level.

This enables you to complete your projects faster, saving you time and increasing your productivity. Additionally, the machine uses TMC2209 silent drivers to reduce the noise of operation, making it a faster and more enjoyable laser engraving experience.

Air-assist Pump

The air-assist pump is a key feature of the LONGER B1 20W Laser Engraver that greatly improves the cutting ability, precision, and quality of the machine. This feature helps to blow away debris and smoke from the cutting area, allowing for cleaner cuts and a better overall experience. The air-assist pump can be automatically turned on/off and is controlled directly by the program, based on the parameters set in Lightburn. This allows for greater control over the cutting process and ensures that the pump is used at the optimal times to achieve the best results.

By blowing away debris and smoke from the cutting area, the air-assist pump helps to prevent any buildup or clogging in the machine's laser head, which can affect the quality and precision of the cuts. It also helps to reduce the risk of fires caused by any buildup of debris in the machine. The air-assist pump is an important feature for those who work with a variety of materials, especially those that tend to produce a lot of debris or smoke during the cutting process.
