Abstract Scope |
Cooperative 3D Printing (C3DP) is an emerging technology designed to address size and printing speed limitations of conventional gantry-based 3D printers. To print large-scale objects, C3DP divides a job into chunks to be printed by a swarm of robots. Previously, we developed a Chunker algorithm to partition jobs into printable parts in the XY direction, which theoretically enables printing of objects of unlimited size in XY dimensions. However, print size is limited in the Z direction due to physical constraints of the system. In this paper, we introduce the first working strategy and rules for Z-Chunking such as where and how to place chunk boundaries and alignment geometries. Additional challenges of interfacing with XY chunking and facilitating reassembly of the job are also considered. We conduct two case studies on objects of varying geometric complexity (e.g., simple solids vs. hollow structures) in which the object is chunked, printed, and assembled. |
