Correlations between Influencing Parameters and Quality Properties of Components Produced by Fused Deposition Modeling

Additive Manufacturing (AM) is often discussed as break-through technology for manufacturing. However, currently AM is primarily used for prototyping [2]. Poor quality of components and unreliable predictability and repeatability of properties inhibit its establishment in full-scale production. To achieve process improvement, correlations between influencing parameters and component properties must be understood thoroughly. This paper presents a state of the art research of effect mechanisms during extrusion of thermoplastic polymers in Fused Deposition Modeling (FDM). The influence of machine and material parameters as well as process adjustments on mechanical properties and geometric accuracy is examined. (C) 2018 The Authors. Published by Elsevier B.V.
