Compression behavior of the wood-inspired cellular structure of acrylonitrile butadiene styrene

In wood science and technology, researchers increasingly focus on the additive manufacturing in different aspects through assembly, mechanical, and physical characterization of the printed parts. One of the main parameters influence the wood features is the inhomogeneity of cellular structure. The effect of dislocation on the compression behavior was evaluated over the wood-inspired cellular structure. The 4.4 x 4.4 mm cross-cut-sized cell (0.8 mm cell wall thickness and 2.8 mm lumen diameter) with 10 mm thickness was arrayed by 6 columns and 3 rows to design the control model. The middle row was 0.8, 1.6, and 2.4 mm dislocated to obtain irregular models. Objects were fabricated through the deposition of acrylonitrile butadiene styrene filament using DaVinci 1.0 all in one three-dimensional printer. The effect of printing orientation (vertical and horizontal) on compression behavior was also figured out. The compression test was performed to obtain the load-deformation behavior of samples. According to the results, the horizontally printed samples presented better performance. Furthermore, horizontal alignment, rectilinear infill type, 90 % infill density, and 0.2 mm layer height combination presented the highest (5719 N) load-carrying capacity. The statistical analysis (P < 0.05) figured out that cell dislocation has significant influences on mechanical properties.
