The team at WobbleWorks has been quick to iterate on the concept of a 3D printing pen in the past 3 years, and it's not stopping any time soon. The startup has unveiled the 3Doodler Create, a third-generation pen that irons out some of the remaining kinks. The refined drive system should give you smoother output, but the real centerpiece may be the ease of use: WobbleWorks is promising simpler controls that get anyone printing "in seconds." It's even a bit flashier, as there's an both an ambient light bar as well as a transparent panel to show what's going on inside.
