Review and hands-on test of the brand new Sculpfun SF-A9 40W diode laser engraver. This laser cutter is lightning fast and incredibly stable and precise laser engraving machine! In this video I will put it through a series of tests to see how well it performs at laser cutting very thick plywood and laser engraving plywood, acrylic, stainless steel, anodized aluminum and much more. I will also measure its laser spot size and its true optical output power. Sculpfun SF-A9 is a big step-up from previous models and it delivers great performance and high quality and high precision.
