++3D printing

Urgh i cant sleep
And all i can think about rite now is about the 3D printing technologies. Boleh tak????
I mean, i wonderr wehh how they did it. Do we have one that i can lean my hands on to in malaysia rite now?

And whats the mass used? Is it paper or plastic or what?

If i could change my profession now, i wanna be in the rnd team about the new technology. Any new tech.
