This innovative gadget will be sure to find uses for anyone who draws their ideas on napkins.

3Doodler is the “world’s first 3D printing pen, and lets you draw three-dimensional structures in midair.

WobbleWorks Toy and robotics company invented the pen, and it is actually affordable.  While most 3D printers can cost thousands of dollars, 3Doodler is available for $75.

It’s not available yet, but shoppers are preordering the pen on Kickstarter.

The quick-setting plastic solidifies in an instant,  but the pen’s metal tip heats to 518 degrees Fahrenheit, using the same material found in many 3D printers. Here’s a video from WobbleWorks showing how it works.
