Atomstack A70 Max vs Sculpfun S30 Ultra 11W
Technical comparison · Diode laser (405–460 nm)
A70 Max and S30 Ultra 11W aren't machines in the same category, even if price puts them closer than the spec sheet suggests: 70W of rated power against 11W is a class gap, not just a price gap. The first is built to cut thick material in batches, the second to engrave with precision on smaller pieces.

| Software notes | The system offers excellent versatility in terms of software control, ensuring native compatibility with standard solutions in the maker industry. It fully supports LightBurn, the most popular professional application for laser cutting and engraving management, and LaserGRBL, an open-source alternative ideal for more straightforward operations. Additionally, the machine features wireless connectivity capabilities that allow file transmission and monitoring via a proprietary mobile application, optimizing the workshop workflow. The absence of restrictions tied to proprietary cloud ecosystems ensures complete offline operational continuity, protecting project privacy and ensuring that the machine remains fully functional regardless of local network conditions. | Fully compatible with industry-standard software such as LightBurn and LaserGRBL. The 32-bit motherboard supports Bluetooth connectivity for wireless control and future expansions. |
The differences that matter
- Rated power: 70W on the A70 Max vs 11W on the S30 Ultra 11W — not a tier difference, a machine-category difference.
- Work area: 850×800 mm on the A70 Max vs 600×600 mm on the S30 Ultra 11W.
- Declared precision: 0.005 mm on the S30 Ultra 11W vs 0.01 mm on the A70 Max — an edge for fine engraving.
- Price: about €1300 for the A70 Max vs €699 for the S30 Ultra 11W.
Which one to choose
Choose A70 Max if…
Pick the A70 Max for thick wood or acrylic in production runs: an 850×800 mm work area and 70W of rated power cut in fewer passes what 11W would need to repeat multiple times, at nearly double the price (about €1300 vs €699).
Choose S30 Ultra 11W if…
Pick the S30 Ultra 11W if the job is engraving more than cutting: a declared precision of 0.005 mm, double that of the A70 Max, matters for fine detail on smaller surfaces, and the price stays under €700.
