Abstract

In order to optimize the efficiency of the Fused deposition modeling (FDM) process, this study used polylactic acid (PLA) material under different parameters (the printing angle and the raster angle) to fabricate specimens and to explore its tensile properties. The effect of the ultraviolet (UV) curing process on PLA materials was also investigated. The results showed that the printing and raster angles have a high impact on the tensile properties of PLA materials. The UV curing process enhanced the brittleness and reduced the elongation of PLA material. Different effects were observed on tensile strength and modulus of specimens printed with different parameters after UV curing. The above results will be a great help for researchers who are working to achieve sustainability of PLA materials and FDM technology.

摘要

为了优化熔融沉积建模（FDM）工艺的效率，本研究使用聚乳酸（PLA）材料在不同参数（打印角度和光栅角度）下制作试样，并探究其拉伸性能。还研究了紫外线（UV）固化工艺对PLA材料的影响。结果表明，打印角度和光栅角度对PLA材料的拉伸性能有很大影响。UV固化工艺增强了PLA材料的脆性并降低了其伸长率。UV固化后，不同参数打印的试样在拉伸强度和模量上观察到不同的效果。上述结果将对致力于实现PLA材料和FDM技术可持续性的研究人员有很大帮助。
