Sped up obviously. I read the other day that someone has created the world's first fully printed metal gun. That's sort of scary when you think about it. For now, the printing process used for the gun is prohibitively expensive for the average joe but we are just at the beginning of the new industrial age (or whatever the future will call it), the technology will become commonplace. You can already buy fairly cheap printers for your home that print in plastic.
