“…However, an important part of the researchers' concerns is related to resolving some dimensional limitations of parts made by engaging Additive Manufacturing (AM) technology as well as settling design issues. In the case of making parts larger than the workspace of 3D printers, researchers propose a solution whereby that part is divided into smaller ones and accumulated by these types of cheap and fast assemblies [8][9][10]. Also, in the context of quick-release assemblies in AM, authors in [11] conducted an experimental study on the determination of the required mating/dismounting force as a function of several predefined parameters.…”

This paper's scope is to develop an intelligible Finite Element Analysis (FEA) method, utilized to determine and quantify the assembly forces required to assemble the snap-fit component, which is made of a glass fiber reinforced polyamide (type 6, 60% glass fiber, PA6 GF50), as well as to determine the snap-fit joint maximum retention forces. The proposed FEA method is to be used in Abaqus as a standard solver type, considering its operation ease and simplicity in creating the model. The setback of implementing the standard solver approach is that during the snap-fit assembly, at a certain point in the simulation, the behavior is transformed from a static movement to a dynamic one, precisely when the snap moves backward in the assembled position, at this point, due to the dynamic behavior of the simulation, the solution will continue to diverge, and the convergence is not achieved.
