Kinematics: 4D printing for foldable, flexible forms

Jessica sez, "Kinematics is a system for 4D printing that creates complex, foldable forms composed of articulated modules. The system provides a way to turn any three-dimensional shape into a flexible structure using 3D printing. Kinematics combines computational geometry techniques with rigid body physics and customization. Practically, Kinematics allows us to take large objects and compress them down for 3D printing through simulation. It also enables the production of intricately patterned wearables that conform flexibly to the body."

The process begins with a 3D scan of the client. This produces an accurate 3D model of the body upon which we draw the form of the desired dress. For this example, the top of the dress conforms exactly to the torso, but the skirt has a larger silhouette, allowing for the dress to drape and flow as the wearer moves.

The surface of the sketched dress is then tessellated with a pattern of triangles. The size of the triangles can be customized by the designer to produce different aesthetic effects as well as different qualities of movement in the dress (the smaller the triangle, the more flexible the structure / the more fabric like it behaves). Next we generate the kinematics structure from the tessellation. Each triangle becomes a panel connected to its neighbors by hinges. The designer can apply different module styles to these panels to create further aesthetic effects.
