US team 3D prints material theorised over 130 years ago

In a first, US-based engineers have 3D printed structures called schwarzites, which were theorised by German scientist Hermann Schwarz in the 1880s. The porous structures are strong, light, and durable materials with repeating patterns. One can make an entire building out of the material, and if something falls on it, it would collapse slowly, protecting whats inside, said a researcher.
