I tried looking in the article for what you meant by "print". I still didn't get it. What do you mean by "print"?

The question I am most fascinated with, which is well beyond the scope of this article, is whether a printer can print itself. Self-replication is a philisophical enigma; if something can self-replicate, then it gains one of the main characteristics of life. Think about the possibilities; we could send a self-replicating spaceship into the cosmos, and everytime it lands, it self-replicates using the materials there and re-launches its copies. this process would be exponential, and would essentially allow us to colonize the entire galaxy in a relatively short period of time.

Like your computer printer.

Your computer printer only prints one thin layer. This printer would print thousands of layers which would probably be a bit thicker and would add up to a 3 dimensional object.

This may sound stupid, but I'm very confused at this concept. So the car is made out of paper?

They are trying to apply similar principals to plane and house construction.

cells already are self-replicating. Or do you mean mankind creating something that is self replicating? First, we need to make things that are self repairing. When they are damaged, they recognize the damage, how to repair and engage in the repair.

A good point. That is a big step in-between. I'm just fascinated with the concept of artificial self-replication. If machines could be made to self-replicate, the possibilities are endless.

Printing a car is too complicated. Cars are too intricate to be made from a single material being sprayed in patterns. Maybe printing car parts, but thats different.

It's already being done. So, obviously it's not too complicated.

Current 3D printers work mainly by polymerizing liquid plastic with a laser or by similarly sintering metal powder. There are a few other specialized processes that do something like squirting glue. The precision available is maybe 10 mils. None of the processes use diverse materials, so making a rubber-covered copper wire is impossible. A sintered engine block would not be strong enough nor precise enough. Cars have sensors and integrated circuits that cannot be made by printing.

Current technology is nowhere near close to being able to print a car. That's very far in the future.

Building a robot that could build similar robots is probably theoretically feasible, though not practical.

Well, given my knowledge of the technology, people aren't printing cars yet.

Like Roy says, the machines don't use diverse materials yet, and the technology is still developing, although I think in 5 to 10 years it might be interesting to see how well it's developing.

On a bragging point, our school's IST teacher actually allowed the students to create one of these machines (from a really complex assembly) . Interesting.
