Everyone is currently all up in Arms (GET IT? DO YOU?) about downloadable guns, which honestly seem terrifying to me, because how do you even regulate those, but I have a much more macro question / concern: WTF IS A 3 D PRINTER AND HOW DOES IT MAKE ACTUAL THINGS? HOW DO YOU PUT THE STUFF IN IT TO MAKE THE THING? HOW DOES IT THEN BECOME A THING, AND DOES IT FEEL AND LOOK LIKE A THING? NO REALLY PLZ SOMEONE EXPLAIN THIS TO ME BECAUSE I CAN BARELY PRINT A SHIPPING LABEL
