This research focuses on the thermal characterization of 3D-printed parts obtained via fused filament fabrication (FFF) technology, which uses a poly(lactic acid) (PLA)-based filament filled with milled carbon fibers (MCF) from pyrolysis at different percentages by weight (10, 20, 30 wt%). Differential scanning calorimetry (DSC) and thermal conductivity measurements were used to evaluate the thermal characteristics, morphological features, and heat transport behavior of the printed specimens. The experimental results showed that the addition of MCF to the PLA matrix improved the conductive properties. Scanning electron microscopy (SEM) micrographs were used to obtain further information about the porosity of the systems.
本研究聚焦于通过熔融长丝制造（FFF）技术获得的3D打印部件的热特性，该技术使用填充有不同重量百分比（10%、20%、30%）热解磨碎碳纤维（MCF）的聚乳酸（PLA）基长丝。采用差示扫描量热法（DSC）和热导率测量来评估打印试样的热特性、形态特征和热传输行为。实验结果表明，向PLA基体中添加MCF可改善导电性能。使用扫描电子显微镜（SEM）显微照片来获取有关系统孔隙率的更多信息。
