3d Printer Babbling
I'm trying out a testcube of the PLA/Carbon Fiber composite right now. Interesting filament - unlike the softer and flexible nylon or PETG stuff, this stuff is actually a bit brittle pre-printing - a bit more flexible than pasta of the same diameter, but you get the idea. You can snap it with a finger. After printing, the various stressors should all cancel out. Or something.
Pretty, if you like that matte black tactical look.
