When it comes to 3D printing, the theme of 2015 is simple: make it useful. The last couple years has been exciting for fans of the technology and people in the industry, as it has developed so rapidly it has been hard to keep up with.
Problem with it was, businesses and consumers still had little reason to invest in 3D printers. Desktop printers are still novelties, mostly used to make silly toys and gadget accessories. Food printers are fascinating, but they're still like something out of Star Trek, is still a distant dream from being in every kitchen. Bioprinters are amazing feats of technology, but having them in hospitals is still years away.
