For reasons of general foolishness, I’m planning to use the GF to cut parts for a small machine, so I’m wondering two things:
what is the stiffest material that can be cut with a 40w laser?
what is the hardest (most wear-resistant) material that can be cut?
In my particular case, a full-size machine would be made primarily of steel, cast iron, and some bits of stainless. I’m looking at making a small very light-duty version out of laserable materials, partly as an experiment and partly because I don’t presently have access to a milling machine large enough to handle this full-sized in metal.
Some parts need to be quite stiff, while other parts need to be as wear (abrasion) resistant as I can manage. So, to be clear, I don’t particularly need to find a single material for both purposes, they’re separate components.
Also, I regard the entire assembly as being fundamentally sacrificial, because if I can manage this in the first place then I don’t mind just cutting replacement parts as the need arises (I’m trying to make a die filer for small nonferrous parts because, again, I’m being foolish).
