Axisymmetric Column No. 1
Description
Axisymmetric Column No. 1 exemplifies a novel approach to large-scale robotic additive manufacturing, utilizing curved-layer fused filament fabrication (CLFFF) on a pre-stretched textile. It explores how patterning affects CLFFF printing to develop a lightweight hybrid shell structure. The cross-ply [0°/90°] and quasi-isotropic [0°/60°/90] patterns, inspired by composite engineering, enhance the mechanical properties of SCF-PLA.
Program Development
The final unit, including the shell structure and the base, has a height of 2300mm with a span of 900mm, and is reinforced by 10 kg of SCF-PLA pellets. The developed nonplanar robotic 3D printing technique was applied in reinforcing an individual axisymmetric column, which is one column out of three-column vault structure.
