| Abstract Scope |
Additive manufacturing (AM) of large objects has, over the last decade, required the scaling of existing material extrusion processes. The current generation of large-scale printers are primarily gantry robots with high throughput extrusion systems. With workspaces approaching 50m3, these printers have pushed the boundaries of achievable print volume while allowing the utilization of low-cost feedstocks, such as cementitious materials and polymer pellets, like those used in injection molding. Continued workspace expansion requires an examination of the inherent tradeoffs, which impact capital and operational costs. In this work, the authors examine these tradeoffs to determine fundamental scaling laws for existing system architectures, survey the state of the art for alternative system configurations and pose recommendations for future system designers to continue the evolution of large-scale AM systems. |
