The Architected Materials and Additive Manufacturing (AM²) Lab at Princeton University is a multi-disciplined research group addressing the need for better civil infrastructure. The group is motivated by intellectual challenges involved in addressing civil infrastructure problems. The main focus of our group centers on understanding and controlling the fracture mechanics of new bio-inspired and architected infrastructure materials such as concrete. We advance the automated robotic manufacturing processes such as that leverage new possibilities in design of new functional materials. We emphasize on holistically improving fundamental mechanical and functional (thermal, water uptake) properties of brittle and quasi-brittle cementitious materials by design and processing, and develop ways to reduce materials use that can be scaled up toward resilient applications in the civil engineering.
