3D Printers

Hmm, has anyone else noticed that 3D printers are essentially 1 step closer to replicator technology in Star Trek? We have them printing food, cars, guns, drugs and a host of misc doodads now...
Imagine 5 years from now when you grabbing cartridges like you do now for inkjets...
How will military deployments look like having the ability to print out any replacement parts tools etc by just having a tanker truck of goo and a printer... what about supply drops to field units, no need to special load the supply drop, all it needs is a canister of goo and a printer. Once the supply drop is ordered, the team requests what they need and in flight the dropbox is already at work printing the supplies requested.

Personally I want to be able to print fantasy miniatures for playing warhammer 40k and dungeons and dragons etc. I mean really, who doesn't want a set of miniatures in their own likeness? $500 + printing supplies is a bit to expensive for personal

use at the moment, I'm just biding my time... Maybe kinko's will offer 5 cent prints.. hmm
