3D printers: Will we soon need a background check to buy ink?
As a teenager I became an avid Trekie, never missing an episode of the original series, TNG, DS9 or STV. Readers who have never heard of Star Trek may be excused now. Over the years a great deal of the futuristic technology featured in the series has actually become a reality. The latest example is the “replicator” used to turn energy into matter, magically creating anything from a replacement warp core part to a steak dinner.
