Abstract

The study investigates some 3D printing output parameters of a polycaprolactone (PCL) wood-based biopolymer, a category of materials obtained by embedding wood-derived components within polymeric matrices. These wood-based biopolymers have garnered significant focus in recent years due to their environmental friendliness and vast potential across many different fields. A full factorial design with three independent variables (layer height, printing speed, and heat treatment exposure time) at three levels was considered. The research explores printing speeds higher than the speed ranges typically investigated in the existing scientific literature on FDM 3D printing of wood-based polymers. Additionally, in this study, heat treatment is proposed as a post-processing operation to enhance certain crucial proprieties such as surface quality, hardness, mechanical strength, and accuracy. The findings reveal that heat treatment has a positive influence on the investigated output parameters. Notably, 3D printed samples subjected to heat treatment exhibit an average decrease of 112.1% in surface roughness for a 5-min exposure time and 121.73% for a 10-min exposure time. The surface hardness of the samples also improved after applying the heat treatment. The part hardness improved with an average of 0.65%. Furthermore, significant correlations were observed between layer height and surface quality, hardness, printing speed, and tensile strength. Notably, printing speed contributed significantly to the variation in tensile strength, accounting for 52.77% of the parameter’s variation. These insights shed light on the optimization of 3D printing processes for wood-based biopolymers, paving the way for enhanced performance and applicability across diverse fields.

热处理对 FDM 制造的 PCL 木质生物聚合物某些力学性能的影响
该研究调查了聚己内酯(PCL)木基生物聚合物的一些三维打印输出参数。近年来,这些木基生物聚合物因其环保性和在许多不同领域的巨大潜力而备受关注。研究采用全因子设计,考虑了三个层次的自变量(层高、印刷速度和热处理曝光时间)。该研究探索的打印速度高于现有木基聚合物 FDM 3D 打印科学文献中通常研究的速度范围。此外,本研究还建议将热处理作为一种后处理操作,以提高某些关键特性,如表面质量、硬度、机械强度和精度。研究结果表明,热处理对所研究的输出参数有积极影响。值得注意的是,经过热处理的 3D 打印样品在 5 分钟暴露时间内表面粗糙度平均下降了 112.1%,在 10 分钟暴露时间内表面粗糙度平均下降了 121.73%。经过热处理后,样品的表面硬度也有所提高。零件硬度平均提高了 0.65%。此外,还观察到层高与表面质量、硬度、印刷速度和拉伸强度之间存在明显的相关性。值得注意的是,印刷速度对拉伸强度的变化影响很大,占该参数变化的 52.77%。这些见解为优化木基生物聚合物的三维打印工艺提供了启示,为提高性能和在不同领域的适用性铺平了道路。
