This paper investigated the hardness property of PLA samples printed using fused deposition modeling (FDM) with different process parameters and raster angles. The hardness data were collected from the flat and edge surfaces of the samples. The effect of hardness after UV curing process was also analyzed. The results showed that the printing and raster angles had a significant impact on the hardness value of the PLA part, with a slight increase after UV irradiation. This study provides useful references for the application of FDM.
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.
