Distributed forms of construction in the biological world are characterized by the ability to generate complex adaptable large-scale structures with tunableproperties. In contrast, state-of-the-art digital construction platforms in design lacksuch abilities. This is mainly due to limitations associated with fixed and inflexible gantry sizesas well aschallenges associated with achieving additively manufacturing constructs that are at once structurally soundandmaterially tunable. To tackle these challengeswe propose a multi-nodal distributed construction approach that can enabledesign and construction of larger-than-gantry-size structures. The system cangenerate and respond tointegrated real-time feedback for parameters such as material curing durationand positionawareness. We demonstrate this approach througha software environment designed to controlmultiple robots operating collaboratively to additively manufacture large-scale structures. We present and report on a novel computational workflow as well aswork-in-progress ofa digital fabrication environment. The environment combinesa centralized system designed to manage top-down design intent given byenvironmental variables, with a decentralized system designed to compute, in a bottom up manner, parameters such as multi-noderule-based collision, asynchronous motion, multi-nodal construction sequence andvariable material deposition properties. The paper reports on a successful first deployment of the system and demonstrates novel features characteristic of fabrication-information modelling such asmulti-nodalcooperation, material-based flow and deposition, and environmentally informed digitalconstruction.
