Lemniscatetra

Curved creases transform thin aluminium sheets into three-dimensional shapes.

Lemniscatetra is a tetrahedral form with Bernoulli lemniscates traced along its edges, approximated through curved creases in thin aluminium sheets. It consists of four modules, each formed by folding three curved creases and assembled into a tetrahedron using bolts. The resulting lightweight geometric structure combines computational design and digital fabrication with traditional craftsmanship. It was designed by participants of the Structural Origami Gathering 2026 as a gift to EPFL’s Bernoulli Center, which hosted this year’s workshop.
