3D-printing pen turns bottles and bags into statues and spaceships
July 13, 2016

3D-printing pens change plastic filaments into a gel that hardens when it hits the air, allowing users to create sculptures freehand. A new company thinks that using all that plastic is expensive and wasteful, and is aiming to create a new kind of 3D pen that does its thing using old plastic bottles, bags and even folders. It's called the Renegade and it's seeking backers on Kickstarter now.

Kind of cool for people that like doing this stuff!
