| Spec | Sculpfun S30 Pro Max | Atomstack A20 Pro V2 |
|---|---|---|
| Optical power | 33W | 20W |
| Design brief | Cut depth first | Balanced value |
| Air assist | Automatic, software-switched | Included pump, manual |

| Street price | Higher, cut-per-dollar strong | Lower entry |
Specs standardized from published manufacturer data and consistent owner reports — we don’t operate a lab.
Sculpfun aimed the S30 Pro Max at exactly one metric — pass depth — and per owner-shared grids it delivers: thicker stock, fewer passes, with the automatic air assist doing quiet quality work on every cut.
The A20 Pro answers with price and adequacy: for coasters, ornaments, and 3mm product lines, its extra passes cost minutes, not sales. Buy the Sculpfun when 6mm+ cutting is your catalog; buy the Atomstack when it is your someday.
