3D printers are getting smaller and cheaper all the time, but they’re still not exactly mainstream. The 3Doodler is an attempt to change that — it’s a small pen-style device that its creators call both a “world’s first” and “the most affordable way to 3D print.” It won’t be able to print pre-rolled objects such as Nokia phone cases, of course, but instead lets you draw your designs into existence by moving it through the air. Like many 3D printers, the 3Doodler uses ABS plastic that is heated and instantly cooled.
