3Doodler is the world’s first 3D printing pen

We wanted to design a 3D printing device that could be used within minutes, without needing any technical knowledge, software or computers. We also wanted it to be affordable as well as fun, so that anyone could 3Doodle! Compact and easy to use, the 3Doodler allows you to literally draw in the air – whether freestyle 3D sketching or tracing shapes from templates to make larger structures and objects
