It’s the year 2013, we survived the Mayan apocalypse, and if you’re keeping count, we’re supposed to have hover-boards and flying-cars in 2 years – at least according to Back to the Future Part II. I hate to be the bearer of bad news, but I don’t think that one is going to happen soon. But I have better news; we’re developing something far more exciting and unimaginably limitless — a replicator straight out of Star Trek! I’m talking about 3D printers: devices and services which allow you to design and build your own products, craft experiences catered specifically to meet your design needs, and make your ideas directly from your home without ever having to stock parts. The third industrial revolution is here and it’s something to get really excited about.
