Discover the Longer Laser B1 20W. Featuring a 22W optical power, 450x440mm work area, and speeds up to 36,000 mm/min. Ideal for wood, metal, and acrylic.
Cuts 10mm wood cleanly in one pass and engraves with excellent detail. Great value overall.
Setup took under an hour and everything worked as expected. Instructions were clear.
The laser cuts well but the air assist pump is louder than I expected.
Managed to create beautiful colored patterns on stainless steel. Definitely a highlight feature.
Power is great, but I wish it had autofocus. Changing material thickness slows down workflow.
The Longer B1 20W offers exceptional power and speed for its price point, making it a strong contender for hobbyists and small businesses who prioritize performance. Its large work area and smart air assist are standout features, though users must be prepared to implement their own safety enclosure and fume extraction.
