| Abstract | Additive manufacturing (AM), commonly known as 3D printing, has been available commercially since the last three decades. The global market for 3D printing has rapidly evolved, and the attention has swapped from hobbyists towards various industries such as aerospace, automotive, electronics, etc. In most large-scaled AM the method employed by Fused Deposition Modeling (FDM) is a slow fabrication procedure because the maximum velocity of the print head is limited to the maximum feed rate of the thermoplastic. There exists an inherent trade off within AM between the layer resolution and the overall scale of printed parts. In order to solve the universal problem of fabrication time, elevating the collaborative 3D printing process in which a swarm of printers work together on a common platform can shorten the fabrication time. According to the previous research, it is found that they can only be used to solve for simple parts by creating the chunks or segments and scheduling the printing job to avoid collision between nozzles. This paper fulfills a gap for the complex parts and situation as a new contribution by fabricating simultaneously and needlessly to set the interference zones or chunks. Moreover, in the mechanism of operating the printers, instead of using robotic arms, the design of the 3D printers is favorably changed. The market offers a fairly large selection of 3D printers with different designs and kinematics. However, the sizes of the commercial 3D printer’s design are strictly constrained by the chamber volume of the printer, which can print parts whose sizes are no larger than its volume. This paper presents the design process and the development of a telescopic arm 3D printer which is modular type design. Once planning to fabricate multiple parts at the same time in the common working area, some considerations come into play in the system. Therefore, multiple g-code simulation, collision identification and modification are discussed and implemented in this paper. |
