Frequently Asked Questions

Which is better, the Sculpfun SF-A9 or ACMER P2 33W?

It depends on your use case. Sculpfun SF-A9 is 40W diode. ACMER P2 33W is 33W diode. See the decision guide and side-by-side specs above.

What materials can both the Sculpfun SF-A9 and ACMER P2 33W cut or engrave?

Both machines have community-tested settings for 21 shared materials. The settings table above lists every material with side-by-side speed, power, passes, and air assist values for direct comparison.

Is the Sculpfun SF-A9 (40W) much faster than the ACMER P2 33W (33W)?

Higher wattage typically means faster cutting and the ability to cut thicker material in fewer passes. The Sculpfun SF-A9 (40W) cuts thicker material in single passes and engraves at higher speeds than the ACMER P2 33W (33W). For raster engraving the difference is smaller because surface engraving is limited by mechanical scan speed.
