Origami is considered by designers to be a useful method for constructing elegant, compliant mechanisms using a single geometry. Such “compliant mechanisms” make targeted use of material properties and achieve a high degree of stability with simple shapes. However, origami principles rarely appear directly in 3D-printed components. In a video, developer Matthew Lim examines how folding patterns can be transferred to printed parts.
In his first approach, Lim transfers basic folds to thin, 3D-printed plates. He deliberately reduces the material thickness along the fold lines. This keeps the flat areas rigid, while the transitions serve as bending zones. The principle works for simple patterns, but reaches its limits with more complex geometries. According to the presentation, if the fold lines become more numerous, they are subjected to higher loads, weaken, and can overstretch until they fail.
For these cases, Lim uses an adaptation derived from preliminary work. In this case, fold lines are located on alternating sides of the panels. He uses offset panels for this, which enables more complex folds with improved properties. The approach also allows the panels to be made thicker overall without completely losing the mobility of the folding zones. This shifts the compromise between stability and flexibility in favor of more robust structures.
In addition to the folding patterns, Lim is also testing prints that are more focused on compliant mechanisms. These include twisted cylinders that contract when deformed. He sells the models via his Patreon page.
