The most additive manufacturing technologies share the similarity in production of parts layer by layer on the basis of physical models created with three-dimensional computer aided design (CAD) models. In contrast to the longer on market available additive manufacturing methods, the principle of Arburg Freeformer base on melting of conventional plastic granules with an injection molding plasticizing unit as base material. A stationary discharge unit with an integrated nozzle- valve system applies thin plastic droplets layer by layer onto a component carrier using high frequency piezo technology to open and close a nozzle-valve system at a specified cycle of 60Hz to 200Hz. Compared to fused filament fabrication (FFF), which is the most common process in additive manufacturing with material extrusion, the Arburg Freeform System (AFS) has a higher degree of freedom in material variation. In this work, structural properties are correlated with the mechanical and physical properties of additive manufactured thermoplastic polymers. Focused are investigations of interlayer adhesion of layerwised build specimen and parts.
