The Architected Materials and Additive Manufacturing (AM²) Lab at Princeton University is a multi-disciplinary 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 bio-inspired and architected materials such as concrete and composites using experiment, simulation (phase-field and cohesive zone models), and theory (fracture and statistical mechanics). We advance the robotic manufacturing processes that enabled transitioning from automation to autonomy using feedback, path planning, and sensing. These advancements in additive manufacturing techniques further leverage new possibilities in design of tough and functional engineering materials.  We emphasize on wholistically improving fundamental mechanical (toughness, ductility) and functional (thermal, water/carbon uptake) characteristics in purposefully designed heterogeneous materials. The inceptions and investigations of the lab in the areas of mechanics and robotics aim to address need for resilient, adaptable, and conscious engineering materials.
