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.
The Create costs $100, or about as much as the earlier 3Doodler 2.0. However, you won't have to shell out full price if you've been enamored with the idea for a while. If you own the 2.0 model, you'll get half off the price of the Create if you order it by June 3rd. It's hard to say how much of an improvement you'll see, but it could be easy to justify the outlay if you prefer to draw your ideas with plastic.
