Solid Concepts, which last month revealed the first fully-functional, metal 3D gun
Hold on, I'm pretty sure guns existed long before this "Solid Concepts" company, and they were all 3D too. Granted, it's hard to tell if the gun is just hung on a wall, since you only perceive one side of it and it looks flat from a distance, but if you pick it up and rotate it around you'll see that it indeed occupies a volume.
that's why you can buy it for 99
99 what? Problems but a bitch ain't one? Bottles of beer on the wall? Luftballons? Yard Touchdown?
