Koala: incredible 3D printer 'climbs' its printed structures for unlimited Z-axis building

Researchers at the University of Chile have developed two working prototypes of Koala 3D, a free-form “climbing” 3D printer with an unlimited Z-axis. The unusual 3D printer can climb the object it is currently printing in the same way a koala climbs a tree. Over the years, there have been a handful of clever tricks for extending an axis (or axes) of a 3D printer, allowing for larger or even unlimited 3D printing in one direction. In May 2017, for example, we learned that a Dutch 3D printing company called Blackbelt 3D had developed a conveyor belt 3D printer […]
