增材制造近年来越来越受欢迎，因为它能够直接从CAD数据创建原型以及功能和最终用途产品，而不需要任何特定的工具要求。熔融沉积成型（FDM）是一种广泛应用的增材制造技术，用于制造与注塑成型部件相媲美的功能性聚合物最终用途部件。FDM打印件在汽车、航空航天、医疗、电子等领域有着广泛的应用。然而，由于FDM零件的力学性能差，影响了其应用。合理选择工艺参数可以提高打印件的力学性能。在本研究中，进行了实验研究，研究了打印部件的力学性能与工艺变量的关系。通过改变栅格角度、栅格宽度和层高三个过程变量来了解其对拉伸强度的影响。此外，还研究了工艺变量对断裂表面的影响。关键词：3d打印，熔融沉积建模，层高，光栅角度，光栅宽度，抗拉强度。
Additive manufacturing gains the popularity in recent times, due to its capability to create prototype as well functional as end use product directly from CAD data without any specific requirement of tooling. Fused deposition modeling (FDM) is one of the widely used additive manufacturing techniques that are used to create functional end use part of polymer that is comparable with the injection-molded parts. FDM printed part has an application in various fields such as automobile, aerospace, medical, electronic, etc. However, application of FDM part is greatly affected by poor mechanical properties. Proper selection of the process parameter could enhance the mechanical performance of the printed part. In the present study, experimental investigation has been carried out to study the behavior of the mechanical performance of the printed part with respect to process variables. Three process variables viz. raster angle, raster width and layer height have been varied to understand its effect on tensile strength. Further, effect of process variables on fractured surface has been also investigated. Keywords—3D printing, fused deposition modeling, layer height, raster angle, raster width, tensile strength.
