Scalable, Flexible and Resilient Parallelization of Fused Filament Fabrication:Breaking Endemic Tradeoffs in Material Extrusion Additive Manufacturing
Jeremy Cleeman,Alex Bogut,Brijesh G. Mangrolia,Adeline Ripberger,Kunal H. Kate,Qingze Zou,Rajiv Malhotra +6 more
TL;DR: In this paper , a new paradigm for parallelized MatEx of thermoplastics called Multiplexed Fused Filament Fabrication (MF3) is presented, which can print non-periodic 3D structures, larger contiguous parts or multiple smaller distinct parts or a mixture of both, on the same machine, without the limitations of state-of-the-art parallelization methods.
