Abstract
Snap joints provide the opportunity of joining two components in a very simple, economical and rapid way. Therefore, snap joints are a feasible option for assembly of prototypes. Snap joint design guidelines currently focus on injection-molded parts, which may not be suitable for rapid prototyping. In contrast to injection molding, additive manufacturing provides a higher degree of design freedom. Applicability of design guidelines for injection-molded snap joints to additive manufacturing technologies has not been comprehensively investigated yet. In this work, we present a study comparing mechanical properties of snap joint specimen that are manufactured from three different materials with the two manufacturing processes FDM and SLS. Results show significant impact of both material and manufacturing technology. The presented results may lead to improved design guidelines for additively manufactured snap joints.
