abstract⁄Extrusionbased additive manufacturing AM is gaining traction in the construction industry, offering lower environmental and economic costs through reductions in material and production time. AM designs achieve these reductions by increasing topological and geometric complexity, and through variable material distribution via customprogrammed robot tool paths. Limited approaches are available to develop AM building designs within a topologically free design search or to leverage material affects relative to structural performance. Established methods such as topological structural optimization TSO operate primarily within design rationalization, demonstrating less formal or aesthetic diversity than agentbased methods that exhibit behavioral character. While materialextrusion gravitational affects have been explored in AM research using viscous materials such as concrete and ceramics, established methods are not sufficiently integrated into simulation and structural analysis workflows. A novel threepart method is proposed for the design and simulation of extrusionbased AM that includes topoForm, an evolutionary multiagent software capable of generating diverse topological designs matForm, an agentbased AM robot toolpath generator that is geometrically agnostic and adapts material effects to local structural and geometric data and matSim, a materialphysics simulation environment that enables highresolution AM material effects to be simulated and structurally and aesthetically analyzed. The research enables designers to incorporate and simulate material behavior prior to fabrication and produce instructions suitable for industrial robot AM. The approach is demonstrated in the generative design of four AM columnlike elements.
