Matter Lab presents 4DMesh, a method of combining shrinking and bending thermoplastic actuators with customized geometric algorithms to 4D print and morph centimeter-to meter-sized functional non-developable surfaces. With their tools, users can input CAD models of target surfaces and produce respective printable files. The flat sheet printed can morph into target surfaces when triggered by heat.

This system saves shipping and packaging costs, in addition to enabling customizability for the of relatively large non-developable structures. They designed a few functional artifacts to leverage the advantage of non-developable surfaces for their unique functionalities in aesthetics, mechanical strength, geometric ergonomics and other functionalities.
