SCULPFUN S30 Ultra and ATOMSTACK A30 PRO are both 33W lasers with 144W of electric output. They do, however, differ in both focus spot and engraving accuracy, except for the visible engraving size. The S30 ultra features a slimmer focus spot of 0.08*0.0mm; while the ATOMSTACK A30 PRO has a slightly bolder 0.08*0.1mm. This is also true for the engraving accuracy, namely, the S30 ultra with 0.005mm, while the A30 PRO is 0.01mm.
