The Sculpfun SF-A9 is a 40W diode laser engraver. This page lists 62 community-tested settings covering speed, power, passes, air assist, and DPI across a range of materials. Always run a test cut on scrap material first — results vary depending on your material batch, focus, and ambient conditions.
The Sculpfun SF-A9 is Sculpfun's enclosed diode laser, combining the safety and smoke containment of a fully enclosed design with LightBurn compatibility. The enclosed build makes it more home-friendly than open-frame Sculpfun models. Best for wood, leather, slate, and light acrylic cutting. A good alternative to the xTool S1 at a lower price point.

Can the Sculpfun SF-A9 engrave metal?
