All three share the same sturdy frame and large work area; the difference is optical power. Higher wattage cuts thicker material in fewer passes and engraves faster — the 40W is the top choice for production cutting, while the 20W already handles most engraving work.

Depending on the module, the B1 series cuts basswood from around 8mm (20W) up to 20mm+ (40W) in one or a few passes with air assist, plus black acrylic and other common maker materials. Results vary by material density.

Yes — it’s one of the best-value production diode lasers available. High power means faster job turnaround, the large bed handles batch layouts and big signs, and the rigid frame keeps accuracy over long daily runs.

Approximately 450×440mm — one of the largest standard beds among diode lasers. An official extension kit expands it further for oversized signs and furniture panels, and a honeycomb bed with clamps is available to match.

The diode modules mark coated and anodized metals and lightly mark stainless steel. For deep, crisp engraving on bare metals, add the Ruby pulsed infrared laser module — it mounts directly on B1 series machines.

A full ecosystem: extension kits, fitted enclosure, smoke purifier, air assist, rotary roller and chuck, honeycomb beds, camera kit for monitoring, touchscreen, and raiser kits for taller objects.

Yes. The B1 series is fully compatible with LightBurn and the free LaserGRBL, so it drops straight into professional workflows with camera alignment, layer control, and material libraries.

Strongly recommended for cutting: air assist produces cleaner edges, deeper cuts, less charring, and protects the lens. Most B1 configurations support LONGER’s air assist kits, and many bundles include it.

Treat it with respect: always wear wavelength-rated goggles, keep the enclosure closed if fitted, vent fumes through a smoke purifier, and never leave it unattended while running. The B1 includes built-in safety protections and a sturdy frame.

LONGER backs the B1 series with an official warranty, lifetime technical support, and a full stock of genuine spare parts — modules, lenses, touchscreens, and boards — so downtime stays minimal.
