Print Your Lunch

File this one under “Weird But Possibly Amazing”: Relevant magazine reports that 3-D printed food might be at hand (yes, you read that right), and some people think this might be a step toward ending, or at least alleviating, world hunger.

You can already print all kinds of things — including prosthetic  and maybe even organs — cheaply. Imagine ordering something online, then just printing it right there at your desk. The possibilities seem endless.

The potential upsides are clear. Are there downsides?
