Christoph Schindler, co-founder of schindlersalmerón, develops the principle of ZipShape since 2007, in order to build curved elements from cnc-manufactured plain material without molds.
An element consists of two differently slotted panels that only interlock if bent to the desired curvature.
A grasshopper definition worked out during a workshop at the CITA Copenhagen shows the dependency between slot geometry and global curvature.
The newest development allows the fabrication of developable twisted surfaces.
This principle has been applied to a sculpture produced and tested at the Bern University of Applied Sciences in Biel.
