2013's Biggest Tech Moments

3-D Printing Expands in All Directions

Almost 30 years after its 1984 debut, 3-D printing is busting out all over. The intervening progress has seen the technology develop from a narrow, specialized manufacturing gimmick to a revolutionary $2.7-billion industry [sources: Leckart; PC Magazine]. To take two extreme examples, bioprinters today can run off organics ranging from food to human tissue, while plans published online for 3-D-printed guns pose a challenge to existing gun laws and enforcement [source: Leckart].

Today, people print simple robots, functional cameras, self-portrait action figures, musical instruments, phone cases, toys, sports equipment and bits and bobs for around the house [sources: Carmichael; Nosowitz]. Sure, right now the products might look like something assembled in Minecraft, but the technology continues to improve and should become cheaper as more people adopt it. Scanners, for example, continue to grow more affordable, accessible and portable. One example, Structure Sensor, clips to an iPad.

As 3-D printable electronics become more common, we could one day soon print our own tablets, phones and household gadgets. And as prices drop, the technology could revolutionize the making and distributing of life-saving devices like simple water filters or self-closing pit latrines. Our plastic-fantastic future begins today.
