Snap-fit is one of the most important joining methods for plastic products. Since the function and performance of snap-fit often require sensitivity evaluation, prototyping before mass production is important. FDM is one of Additive Manufacturing, and FDM is considered to be suitable for snap-fit prototyping. On the other hand, since the mechanical properties of FDM vary depending on the processing conditions, it is important to verify the relationship between the processing conditions and snap-fit mechanical properties. In addition, in recent years, plastic products have become smaller in some areas. In the case of cantilever-type snap-fit, it is necessary to evaluate the effect of shear deformation as the aspect ratio decreases. In this study, the effect of processing conditions on mechanical properties of snap-fit with different aspect ratios fabricated by FDM were investigated.
