In this paper, the concept of steel fiber reinforced concrete (SFRC)-plastic columns was explored and discussed. Plastic served as a 3D printed formwork that remained in place. Five different column cross-section shapes, based on Cesaro fractal iterations, were created and filled with steel fiber reinforced mortar. After curing, the specimens were loaded and load-strain characteristics were recorded, with a focus on destruction characteristics and energy dissipated up to 6.0% strain. The results showed that columns with fractal-based cross-sections had smooth destruction with significant formwork deformation. All columns exhibited highly quasi-plastic behavior. The results demonstrate the feasibility of replacing traditional formwork and concrete with a more automated 3D printed plastic and SFRC solution. Future research should focus on large-scale columns and other structural elements.
