A Kickstarter.com project called 3Doodler has a unique twist on 3D printing, it’s a pen. The team that invented this device have taken the extruder head from a 3D printer and packed it into a wireless pen. This is another example of the 3D printing phenomenon taking hold, but this time at a lower price point and and even lower learning curve. I think it will be fun for those that don’t want an expensive, hard to program printer. It may also be a hit with children, (if the extruder head doesn’t present a burn hazard). Take a look at the video here, and you decide cool or not?
