In an article recently published in the journal Additive Manufacturing, researchers discussed the utility of automated robotic concrete spraying in the digital manufacturing of ribbed concrete shells.

The heart of the four metre tall curved concrete shell is knitted. The structure's formwork is a textile supported by a steel cable-net. The prototype KnitCandela marks the first application that this ...

Let's think of a paper sheet. If we tried to stiffen it from its primary state, it couldn't support its own weight. However, if we bend it, the sheet achieves a new structural quality. The shells act ...

A prototype for an ultra-thin, sinuous concrete roof using innovative design and fabrication methods has been designed and built by researchers from the ETH Zurich. The shell is part of a roof-top ...
