Getting into the nitty gritty of sand  
Created materials in the lab.

Penn Engineering materials scientist Shu Yang and Weitzman School of Design architect Masoud Akbarzadeh teamed up to develop a 3D concrete printing system that captures carbon dioxide and boosts the structural performance of the building materials. The solution is based on diatomaceous earth and offers enhanced carbon capture and structural fortitude while using relatively fewer materials.

The Polyhedral Structures Laboratory is housed at the Pennovation Center and brings together designers, engineers, and computer scientists to reimagine the built world. Using graphic statics, a method where forces are mapped as lines, they design forms that balance compression and tension. These result in structures that use far fewer materials while remaining strong and efficient.
