Remember the 3Doodler? Odds are plenty of you do, seeing as how the company managed to nab a staggering $2.3 million for its $30,000 Kickstarter campaign. For the minority of you who didn't participate, here's a quick refresher: the device is a 3D printing pen. It's a bit like a hot glue gun for plastic -- simple and ingenuous, it melts a single strand of ABS or PLA, allowing you to draw objects in the air, solidifying as you draw up.
The pen was still in early prototype phase when we first saw it, and now, here at IFA its co-creator Max Bogue is showing off the final shipping product (seeing as how Kickstarter funders will be getting theirs later this year). This 3Doodler actually looks pretty similar to that early unit. All the same elements are in place: a slot in the rear to feed in the plastic, the heated tip where it comes out in semi-liquid form, an exhaust fan (which is pretty loud, but should quiet down before people start to get theirs) and two buttons for fast and slow extrusion.
