3Doodler is the maker of the world's first 3D printing pen. 3Doodler pens work by extruding heated plastic which cools and hardens rapidly, allowing you to literally draw in 3D. The 3Doodler range of 3D printing pens are designed to be compact and easy to use, whether you're aged 8 or 80, a hobbyist or professional, anyone can create, make, or fix in 3D. #WhatWillYouCreate?
