MIT Scientists’ “4D Materials” Shape-Shift into Human Face

Nicknamed “active origami,” and referred to as a shape-morphing system, an MIT-developed “4D material” begins flat but can blossom into something more complicated when its surrounding conditions change. Specifically, its 3D-printed lattice structure, which mimics mesh, expands through temperature variation and actually turns into the face of scientist Carl Friedrich Gauss. The visual was reverse engineered and Gauss was selected as the sculptural result to …

Tabasco’s New 3D-Printed Neighborhood

Helmed by housing non-profit New Story (in partnership with Icon and Échale), the city of Tabasco’s 3D-printed neighborhood has received its first two homes.

The walls went up in 24 hours and then human workers added the …
