When describing the actual 3D printing process, a good analogy to use is that of an inkjet printer, which takes information and prints it onto paper, in two dimensions, line by line, from the top down. In a similar fashion, 3D printers take information and print it, in three dimensions, layer by layer, from the bottom up.

Why 3-D Printing Matters
On Star Trek: The Next Generation, crew members use a machine known as the replicator to make replacement parts for the ship, prepare food and fix Captain Picard’s usual: “Tea. Earl Grey. Hot.” Creating something out of nothing, the replicator is, sadly, pure science fiction. But using a newly emerging technology, we can design a wrench, a toy, a bike or a flying monkey, and with a click of the mouse, create it. This replicator is a printer, but what it makes is not a two-dimensional image of the design; not a paper model that folds into a 3-D one. This printer creates, quite literally, the object. Three-dimensional printing is here.
