Kresling fold
Developed by Biruta Kresling, Paris-based architect and researcher on folded structures. The pattern is the result of the natural warping of paper from torsional load. Kresling shows how this warping could be used through an experiment with cylinders and paper. She found that after wrapping...
Mars fold vs Kao fold
Expanding from conventional figurative designs to investigating mathematical properties. Barreto’s ‘Mars’. Mountain folds are indicated by solid lines and valley folds by dashed lines. Fold lines of the same colour have the same fold angle. (a) Fold pattern, (b) partially folded position, and (c) mostly...
Tetrahedral Origami Antenna
It is made from standard paper glued to thin copper sheets. The resulted material is 0.25 mm thick, and is folded into water bomb bases, which interlock with each other, forming a tetrahedron. There is also a reflector and two strip detectors, both of which...
The Maekawa Theorem
The Maekawa Theorem, named after Jun Maekawa, tells us that in flat-folded origami, the difference between the number of mountain and valley creases at any vertex is always two. This is what enables origami pieces to be flattened. To visualize this principle, one can unfold...
