Creality Falcon2 laser engraver
This 22W diode laser is ideal for woodworking projects - that’s where it truly shines.
It can mark metal with the aid of a marking spray (see below), but I wouldn’t call it engraving. For that, you need a fiber laser.
As a diode laser, I think it offers a good balance between power and detail, and if you’re into arts & crafts, it’s definitely useful. If you're into metal working, just get a fiber laser.
Besides wood, you can engrave some plastics, cardboard, leather, and glass, although the latter requires a coating of black paint due to reflections.
Just a note on safety: lasers are dangerous, and you must use proper safety glasses at all times when the laser is in operation. Make sure the glasses cover the wavelength of the laser - in this case, 455nm.
Brilliance metal marking sprays
I used this marking spray to mark steel (1045, 4140, A36) and brass with my 22W diode laser. I wasn’t sure what to expect, as I had no prior experience with lasers, but it worked surprisingly well, even when running the laser at lower power (around 10%).
Before applying it, the part must be clean and degreased. One coat is enough. It doesn’t smell, but it should still be used in a well ventilated area, and a mask is recommended. Once the part is dry, you can proceed with the marking. Afterward, the remaining spray can be wiped off with a rag or paper towel - no special products are required.
Please note: diode lasers aren’t really meant for marking or engraving metals, but if you already own one, this can be a solution for the occasional job.
