Abstract

This paper investigated the hardness property of the fused deposition modeling (FDM)-printed PLA samples via different process parameters of printing and raster angles. The hardness data were sampled from the flat and edge surfaces of the samples. In addition, the effect of hardness characters after the ultraviolet (UV) curing process was analyzed. Furthermore, this research found that the printing and raster angles significantly affected the hardness value of the PLA part, which slightly increased after the UV irradiation. Moreover, the results of this study will provide a reference for the field of FDM application.

摘要

本文通过不同的打印工艺参数和光栅角度，研究了熔融沉积建模（FDM）打印的聚乳酸（PLA）样品的硬度特性。硬度数据从样品的平面和边缘表面采集。此外，还分析了紫外线（UV）固化处理后硬度特性的影响。此外，本研究发现打印和光栅角度对PLA部件的硬度值有显著影响，紫外线照射后硬度略有增加。此外，本研究结果将为FDM应用领域提供参考。
