UC Berkeley Associate Professor of Architecture Ronald Rael's "Cabin of Curiosities" is a livable, water-tight structure in Oakland that was unveiled in May 2018. With succulents growing off the exterior walls and a translucent interior, the cabin catches the eye and inspires wonder. What makes the structure unique, however, is not its beauty, but the fact that nearly every element of the cabin was constructed out of 3D-printed materials. (#33997)
