Rigid origami

Rigid origami is a branch of origami that focuses on folding flat materials, like paper or metal, into three-dimensional shapes without stretching or bending the material itself. Unlike traditional origami, which can allow for soft folds, rigid origami maintains its form due to the use of creases and a set geometric design. This technique has practical applications in fields such as engineering, architecture, and robotics, where it can be used to create structures or mechanisms that are compact when folded and can expand into larger, stable forms when unfolded.
