Sculpfun S30 Ultra 22W vs Sculpfun S70 Max
Technical comparison · Diode laser (405–460 nm)
At 22 W and 70 W (rated by the manufacturer) these two lasers don't do the same job: the S30 Ultra engraves and cuts thinner stock, while the S70 Max goes to thicker plywood and large panels. Choosing between them means deciding whether you really need that power and bed, which cost about €500 more.

The differences that matter
- 22 W vs 70 W → plywood cut up to 10 mm vs up to 20 mm; paulownia up to 30 mm is listed only for the S70 Max.
- Bed 590×595 vs 830×800 mm → footprint 80×84 vs 98×100 cm: the S70 Max needs a much bigger bench.
- Autofocus → only the S70 Max focuses on its own when the material changes.
- Price €999.99 vs €1,499 → the S70 Max costs about €500 more.
Which one to choose
Choose S30 Ultra 22W if…
you work on balsa and plywood in medium formats. It cuts balsa up to 15 mm and plywood up to 10 mm, and the 590×595 mm bed covers signs, cutting boards and small panels. It costs about €500 less and takes 80×84 cm of bench. You give up autofocus and panels larger than the bed.
Choose S70 Max if…
you have to cut plywood up to 20 mm or paulownia up to 30 mm, or engrave a sheet 800 mm wide without repositioning it. It has autofocus, and the included TS1 touchscreen lets you run jobs without a computer. The trade-off is the price, about €500 more, and a footprint of 98×100 cm.
