The verdict

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.
