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.
Speed without losing detail
Same 0.08 × 0.1 mm spot as the entry B1, with fills about two to three times faster in our tests.
450 × 440 mm bed
Room for sign-sized panels, with the same extension kit as the rest of the B1 range.
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
- Keeps the fine 0.08 × 0.1 mm spot of the entry module while cutting faster
- Fills at ~39–88 mm/s: a 10 × 10 cm photo in ~14–22 min
- Basic set at $569.99 on Longer's store (October 2026)
Cons
- Gains are moderate in our benchmarks: a 3 mm square still takes ~7–12 min
- The Pro Max set ($949.99) costs more than the stronger B1 in basic trim
- Longer's 20 mm one-pass claim is far beyond our cut benchmark

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.

Common questions
What does the B1 30W cut in one pass?
Longer's spec sheet claims 20 mm basswood in one pass and 50 mm acrylic maximum. In our benchmarks a 10 × 10 cm square in 3 mm basswood takes about 7–12 min at 3–7 mm/s; around 8 mm basswood and 5 mm dark acrylic are realistic in passes.
Is the 30W the sensible middle of the B1 range?
Often, yes. It keeps the same 0.08 × 0.1 mm spot as the 20W, so engraving detail is unchanged, while cutting and filling faster. Its basic set was $90 more than the 20W and $130 less than the 40W on Longer's store in October 2026.
Which B1 30W bundle makes sense?
Longer listed the Basic set at $569.99, the Pro set at $729.99, the Pro Max set at $949.99 and the Basic set with IR module at $929.99 (October 2026). At Pro Max prices, the 40W basic set ($699.99) becomes a serious alternative if cutting is your priority.

Sculpfun · Diode · $690
The 22W is the middle of Sculpfun's three S30 Ultra heads (11W, 22W, 33W), often sold bundled with LightBurn. The 33W head goes further for thick cuts. Listings that say S30 Ultra 10W or 20W are reseller labels.
xTool · Diode · $499 – $1,229
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.
