3D printing is revolutionizing the way parts are created, offering innovative solutions that compete with conventional manufacturing. In material extrusion, the introduction of filaments reinforced with natural fibers has considerably improved mechanical properties, making them useful in several sectors. However, before printing a part, it is essential to carry out numerical simulation to verify the impact of process parameters on the part quality. The aim of the present paper is to study the mechanical behavior of 3D-printed wood-polymer composites based on a numerical homogenization approach. The effects of wood volume fraction and orientation were discussed. The numerical results were verified using analytical models and experimental data, where a satisfactory agreement was obtained with the well-known Mori–Tanaka model.

摘要

3D printing is revolutionizing the way parts are created, offering innovative solutions that compete with conventional manufacturing. In material extrusion, the introduction of filaments reinforced with natural fibers has considerably improved mechanical properties, making them useful in several sectors. However, before printing a part, it is essential to carry out numerical simulation to verify the impact of process parameters on the part quality. The aim of the present paper is to study the mechanical behavior of 3D-printed wood-polymer composites based on a numerical homogenization approach. The effects of wood volume fraction and orientation were discussed. The numerical results were verified using analytical models and experimental data, where a satisfactory agreement was obtained with the well-known Mori–Tanaka model.
