I've been printing with CF-PETG for a year and love it, prints nice, is rigid and grinds and files easy and takes a M2 tap without a hitch.

I've started using the roll of Prusament PLA that came with the printer, it's silver and looks great and prints nicely but as I found out yesterday is a swine to tap a hole in...as the PLA seems to weld together again and ultimately snapped my M2 tap trying to remove it...the 1.6mm drill for the next hole welded in also and required destruction of a body post to free the drill.

PETG is somewhere in between.

I've not tried any other filament, have any of you guys tried PC or ABS?
