Dream it, design it, print it in 3-D: what can 3-D printing do for you?

Abstract

So maybe we are not all driving to work in a flying car or are being beamed up by a transporter yet, but we should be clearing out a space in the lab and perhaps in the office for a replicator. Sure, they may not work the same as the replicators on Star Trek that instantaneously pop out hot, full-course meals to suit any crew member's whim, but they can generate three-dimensional (3-D) objects to match your computer design.
