Within the scope of this thesis, a fused deposition modeling 3D-printing filament was produced and investigated for processing capability as well as mechanical and physical material properties. Thermoplastic plastics or biopolymers were used as components for this filament in order to ensure compost ability or biodegradability and to achieve the highest possible proportion of renewable raw materials in the filament. As components, thermoplastic starch, polylactic acid and polybutylene adipate terephthalate were chosen based on knowledge gained in preliminary tests with materials and printing parameters. In order to investigate the effects of the components as well as their concentration on mechanical and physical material properties or the process capability, a granulate with 10 different concentrations of the components was produced. The different concentrations, referred to as formulations, were determined by means of mixed model design in the context of the statistical experimental design with specification of upper and lower limits that were subsequently evaluated statistically. From the produced granules, one half was processed into filament and, in succession printed by serial printing into test specimens with a fused deposition modeling 3D printer. In order to obtain reference values for tested properties of measured process capability and material properties, the other half of the granules were processed via an injection moulding machine into test specimens. The aim was to draw conclusions from the behaviour of the material on the mixing ratios of the components during and after processing. This could be achieved by quantitative analysis of resulting parameters, qualitative and quantitative analysis of process capability and statistical evaluation of data from material testing.
