Hi all, I have a 6W laser so I'm thinking the thinnest sheet of aluminum would do the trick. I can't even mark aluminum foil. But in the event that I want to change my laser. Is there a chart of laser power vs material+thickness that is required to absorb all the heat? something like (I'm making this up) 10W = aluminum 2mm 100W = titanium 1ft
As in a backing behind your cuts, to protect the table? Aluminum can cause unwanted, or worse, dangerous, reflections. Avoid metallic or reflective surfaces underneath I would recommend a terracotta tile, or flipped over ceramic tile (again the glazed side can cause dangerous reflections) Fireproof, durable, super cheap from any home store, and no reflections
