TL;DR
Sculpfun's S70 MAX pushes the S-series frame to ~70W optical class for shops that want maximum diode cutting depth without CO₂. Same oversized bed philosophy as S40 MAX: premium pricing and workshop space requirements apply.
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.
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 S70 MAX 70W 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
- 70W: the most cut-focused head in the Sculpfun S70 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

Sculpfun · Diode · $999 – $1,299
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.
Atomstack · Diode · $1,999 – $2,499
AtomStack A70 Max brings 70–77W compressed diode power to an 850×800 mm frame with auto-focus, touchscreen, and claims of 25 mm wood in one pass. Popular 2024–2025 upgrade path for makers outgrowing A40 Pro: still open-frame, not enclosed.
Acmer · Diode · $799 – $1,400
Acmer S2 Pro 48W is Acmer's high-power open-frame option before the enclosed P3. Strong cutting claims: verify optical power and compare to P3 48W enclosed if you need smoke control.
