"Every year, Barilla, the world’s biggest pasta company, hosts a competition to create innovative new pastas for their 3D pasta printer. This year they received 1,300 design proposals, and are still in the midst of testing them out.

And then you press print. The printer builds the pasta layer by layer, with a nozzle that moves along the X, Y and Z axes, spitting out the dough in a steady stream. It takes two to three minutes for the printer to make nine pieces of pasta...Pasta is just one application for 3D printers and food. The first 3D restaurant in the world, Food Ink, is serving printed fine dining dishes like lobster-shaped pastries filled with lobster."
