How can we diversify material application in construction?

Auxetic patterning allows for precise forming of doubly curved surfaces.
Dichroic film interacts differently with light relative to viewing angle.

In tandem, these operations allow planar material to become a measure of surface curvature for any given point along a three-dimensional surface.

Robotic Forming Long Exposure

Forming Process The waterjet-cut aluminum sheet is mounted at the edges to a steel channel frame. The end effector, a hard rubber ball, is pressed into the sheet repeatedly to form the sheet outward.
