3Doodler is a 3D printing pen that was created by a team of toy designers. The 3Doodler pen has a simple plastic extruder at the tip. When pressing a button, a thin string of plastic comes out and hardens. You can use the pen to draw plastic pictures or build 3D objects. People that donated $75 will get a pen and a standard-gauge ABS/PLA plastic. This is the same material used by Makerbot and the plastic is self-feeding. You can create a few dozen objects with one string of plastic.
Peter Dilworth and Max Bogue are toy designers. Dilworth worked at the MIT Media Lab and Bogue worked for WowWee in Asia. This is their first commercial product. The two had a goal of raising $30,000 and ended up raising over $860,000 with 32 days left to go.
