This article presents a novel robot-based 3D printing technique for the automated fabrication
of nonstandard large-scale lightweight structures. The approach offers unique advantages
over conventional approaches to 3D printing: It can be performed freely in space, it is
scalable, and it enables the fabrication of structures from a filament 3D printing process. A
first full-scale demonstration case—the architectural installation Iridescence Print—was
exhibited at the Palais de Tokyo in Paris. Based on ongoing research and teaching …
