TL;DR
Longer Laser B1 30W is the 30W SKU on the Longer longer laser b1 line. Longer's large-format B1 20W diode: this profile is the 20W SKU only; Longer also sells 30W and 40W B1 machines separately. Verify optical power on the listing: do not assume combined-watt marketing.
Best for
What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Open-frame : plan safety first
There is no factory enclosure: you wear OD-rated glasses, control smoke, and keep kids/pets away. You trade cabinet convenience for price and access : fine in a dedicated workshop, stressful in a living room without a plan.
Air assist included
Factory air assist blows smoke out of the kerf for cleaner cuts : especially acrylic and dark wood. If it is included, you skip the first upgrade most open-frame owners buy separately.
LightBurn compatible
LightBurn support means advanced layers, camera tools, and workflows many makers outgrow the stock app with. Confirm your exact controller board before assuming full features : some machines need a paid license separately.
Our verdict
Ideal if you
Longer Laser B1 30W targets mixed engraving and wood-cutting weeks: fewer passes on basswood and dark acrylic than weaker SKUs in the same line.
Skip if you
Wrong pick if you never engrave and only wanted the lowest price. Ultra-fine photo work can look better on an engraving-first SKU. Open-frame: safety and smoke are on you.
Pros
- Strongest cut headroom in the line: about 8 mm basswood-class stock in benchmarks
- 30W: the most cut-focused head in the Longer Laser B1 line
- Open-frame: plan laser glasses, exhaust, and workspace rules from day one
- Software on the profile: trial your workflow on scrap before production
Cons
- Clear cast acrylic and thick production cutting still favor CO₂, not diode power alone
- Confirm optical wattage on the listing before you buy

This profile is the 30W SKU on Longer Laser B1. Read the TL;DR and benchmarks above, then compare other power options via the chips before buying.
Pro tips
Tune cut passes with air assist and focus checks. For photo engraving, slow down vs your cut presets: this head is optimized for throughput on wood, not only finesse.

Sculpfun · Diode · $690
The 22W S30 Ultra is what Sculpfun sells today as the top open-frame Ultra config (often bundled with LightBurn). Best cut headroom in the family; do not confuse with older 10W or 20W listings.
xTool · Diode · $549 – $699
Launched May 2026, the M2 packs laser engraving, cutting, and integrated inkjet color printing into one enclosed desktop at $599. Built for everyday crafters and Etsy sellers who want color + laser without a pro CO₂ budget: not a metal-marking or production cutter.
xTool · Diode · $699 – $899
The 20W D1 Pro module is xTool's most popular open-frame head: mixed engraving and light cutting on the large D1 bed. Verify optical power on the listing; swap to 40W later if cut jobs dominate.
