40W Laser Engraver Machine - Diy Cnc Engraving Cutting Machine

Laser wavelength: 445±5nmInput power: 80WLaser output power: 10WLaser type: Diode Assembly required! There is a USB with assembly diagrams, safety info/instructions, drivers, and software (LaserGRBL, Laser Web, and trial of Lightburn). According tto the documentation, the laser will engrave/cut:Papertwo-colour plate (0-4mm)Leather (0-3mm)Opaque plastic (0-4mm)Plywood (0-5mm)Solid wood (0-4mm)Opaque acrylic (0-4mm)Oxidized lacquered metalStainless steelTranslucent and reflective material (eg clear acrylic, metals) cannot be engraved or cut, but the surface of the translucent / reflective material can be painted or masked for engraving. I was a bit confused about these laser engravers because they seem to say different things in different places, so I've done a little research and I'll tell you my findings here (for other people with little/no experience with these, like me, who may have ended up here looking for a low-cost machine): 40W and 80W refer to the power going into the laser. The laser itself has an output power, which is a fraction of this (the rest of the energy is lost through heat).

This is pretty normal and seems consistent across manufacturers: a 40W laser will have 5 to 5.5W actual output, an 80W laser will have about 10W output. A 40W laser can do everything an 80W laser will, just more slowly (slightly less than half the time/passes) - this means an 80W laser will save you time AND laser life. However a 40W laser is still perfectly good, especially if you are working only with thinner materials.
