For the past few years, 3D printing has been revolutionized. Evolving from the little plastic models to human organs, the technology is also advancing in other regions. The 3Doodler is a pen that takes ABS and hardens it almost instantly. this allows the user to effectively draw in the air.

This image was one of the many designs made with the pen. Unlike conventional printing, this process has an infinite space to work with. It is not bounded by the fixed dimensions of the printer’s tray. If he wished, the artist could have made a life-sized cathedral instead of a model, provided he had enough ABS.
