Released November 2022
TL;DR
S30 Pro Max 20W is Sculpfun's earlier high-power open-frame. Still capable for wood and leather; Ultra 22W/33W superseded it for new buyers but used units remain popular.
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 S30 Pro Max 20W is the versatile hobby / side-business SKU: clean engraving and light wood or leather cuts with comparable benchmarks on Maker Atlas.
Skip if you
Open-frame: glasses and exhaust required. Not a CO₂ replacement for clear acrylic or heavy thick-stock production.
Pros
- Everyday engrave and light cut mix: typical 5 mm basswood in several passes
- 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

Machines in the same space, picked from our database by type, price, and score.
Sculpfun · Diode · $450 – $650
The 20W S30 Ultra is the balanced pick in the line: compressed beam cutting on thin wood, large community settings library, and the same stiff frame as the 22W refresh.
Sculpfun · Diode · $399 – $549
Sculpfun S10 10W launched in 2025 as a mid-size open-frame engraver with a sturdier industrial frame than S9, ~385 mm work area, and detachable laser cover. Positioned between budget S9 and S30 families for makers who want better rigidity without Ultra pricing.
Ortur · Diode · $140 – $1,740
The 20W LM3 is the configuration most buyers mean when they say 'Laser Master 3'. Strong engraving, light cutting, huge community: verify you are not accidentally ordering the 10W SKU.
