The Architected Materials and Additive Manufacturing (AM²) Lab at Princeton University is a research group addressing the need for advanced engineering materials and structures enabled by development of novel manufacturing techniques. Using experiments, simulation, and theory, the focus of the group centers on understanding and controlling the fracture mechanics of bio-inspired and architected materials using fracture mechanics, computational mechanics (phase-field and cohesive zone models), and statistical mechanics. We advance a wide range of robotic, additive, or laser-based manufacturing processes that enable enhanced mechanics and functions of the materials.  Advancing robotics in additive manufacturing represents upcoming transition from automation to autonomy by improving the control (feedback), path planning, and sensing. These advancements in additive manufacturing techniques reciprocally leverage new possibilities in design of tough and functional heterogeneous 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 engineering materials and advanced manufacturing methods of construction.
