I have a question regarding the laser engraver module:
Is it possible to use the standard 200mW 405nm InGaN laser for metal laser marking? Using a special laser marking coating like Ferro CerMark LMM6000 or TherMark LMM14 applied onto the surface of various metals (aluminum, brass, stainless steel…) in order to engrave -durable print actually- logos and texts?
If this is possible, what would be the thinnest detail that could be achieved through such a process (what minimum, still readable font size)?
