Beschreibung
In this dissertation, the combination of injection molding and 3D
printing is examined. Some applications for the process combination are
shown with a focus on the investigation of the local reinforcement of
injection molded parts. For the investigation of the reinforcement,
3D-printed inserts (fused deposition modeling) are overmolded in a
tensile test tool adapted for the production of hybrid components.
Different materials and geometries were used in order to investigate
effects, interactions and the limits of the process.The utilized materials are comprehensively characterized and the
manufacturing processes are closely examined, with the main focus on the
process of fused deposition modeling. This process is described in more
detail based on extensive research and tests.It could be shown that with certain material combinations and
geometries, strength increases can be achieved in hybrid components
compared to purely injection molded components. However, it turned out
that the combination of glass fiber reinforced insert material with
injection molding materials due to outstanding glass fibers can lead to
premature failure of hybrid components with an unfavorable design
