Item Fieldable Platform for Large-Scale Deposition of Concrete Structures(University of Texas at Austin, 2018) Chesser, Phillip C.; Post, Brian K.; Roschli, Alex; Lind, Randall F.; Boulger, Alex M.; Love, Lonnie J.; Gaul, Katherine T.Oak Ridge National Laboratory’s Manufacturing Demonstration Facility is developing a novel, large-scale additive manufacturing, or 3D printing, system. The Sky Big Area Additive Manufacturing (SkyBAAM) system will ultimately be a fieldable concrete deposition machine with pick and place abilities that will allow for full-scale, automated construction of buildings. The system will be implemented with existing construction equipment meaning conventional cranes will be used to suspend the print head. SkyBAAM will be cable-driven by four base stations and suspended from a single crane. The elimination of a gantry system, found commonly in large-scale additive manufacturing systems, will enable SkyBAAM to be quickly set up with minimal site preparation. The medium-scale version of SkyBAAM is currently in development. The system design, cable stiffness analysis, and tactics for freezing rotational degrees-of-freedom (DOF), detailed in this paper, will provide a basis for the final, large-scale version of the SkyBAAM system.Item SkyBAAM Large-Scale Fieldable Deposition Platform System Architecture(University of Texas at Austin, 2019) Chesser, Phillip; Post, Brian; Lind, Randy; Roschli, Alex; Atkins, Celeste; Boulger, Alex; Mhatre, Paritosh; Lloyd, PeteOak Ridge National Laboratory (ORNL) is currently developing a concrete deposition system for infrastructure-scale printed objects. This system, called SkyBAAM, uses a cable driven motion platform to manipulate the print head. This work focuses on the general aspects of the system architecture, including arrangement of the cable driven platform, general high-level control methodology, and system accuracy, along with concrete deposition methods. Results and demonstration prints will be shown.
