TL;DR
The S40 MAX (2025) targets makers who outgrew 400 mm frames: 830×800 mm work area, 48W optical power, auto-focus, and Wi-Fi via TS1 screen. Built for sign panels and batch cutting: verify shipping weight and workshop space before ordering.

Best for
What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Autofocus / height sensing (Z-style)
The machine measures material height (autofocus, LiDAR, or probe-style sensing) so the lens sits at the right distance before the job starts : you are not dialing focus by hand on every new thickness. Huge time saver on mixed scrap, warped boards, and CO₂ beds with varying acrylic sheets.
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.
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
Sculpfun S40 MAX 48W 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 20 mm basswood-class stock in benchmarks
- 48W: the most cut-focused head in the Sculpfun S40 MAX line
- Open-frame: plan laser glasses, exhaust, and workspace rules from day one
Cons
- Clear cast acrylic and thick production cutting still favor CO₂, not diode power alone
- Confirm optical wattage on the listing before you buy

Pro tips
Use Z-axis offset per pass in LightBurn for flatter thick cuts. Budget 50L+ air assist for claimed one-pass thick cuts.

Creality · Diode · $799 – $1,099
Creality Falcon2 Pro 40W is the 40W SKU on the Creality creality falcon2 pro line. Creality's top open-frame diode at 60W combined (22W optical class). Verify optical power on the listing: do not assume combined-watt marketing.
Longer · Diode · $699 – $949
Longer Laser B1 40W is the 40W 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.
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.
