New on Kickstarter is the 3Doodler, a 3D printing pen. This item is essentially a hand held extruder that allows users to draw their designs in 2D or 3D space. I think the novelty of this will appeal to many users but I think there are hidden benefits to the device also. The pen should also be able to be used as a welder to attach two prints together or to fix cracks that may have occurred in your prints. This option alone could be worth the early bird $75 entry price but I feel like there will also be lots of fun 3D doodles in our future.
