Optimization of 3D printing parameters for PVDF and characterization by tensile and compression tests.

Fused deposition modeling (FDM) is one of the most important additive manufacturing (AM) processes. The next step for additive manufacturing, which is expanding, is to be productive compared to conventional manufacturing methods. To achieve this, it is crucial to understand FDM productivity, in particular its parameters, which regulate the manufacturing operations productivity rate. Techno polymers are advanced plastics with superior properties when compared to traditional plastics. They are designed to withstand extreme heat and mechanical stress. PVDF [Polyvinylidene fluoride] is a high-performance Techno polymer with exceptional thermal and chemical resistance for industrial grade printing. The objective of this study is to examine the parameters of 3D printing in order to produce functional polyvinylidene fluoride (PVDF) structures with desirable mechanical properties. Different combinations of deposition conditions are tested, and the influence of these parameters on the final dimensional accuracy, microstructure, and effective mechanical strength of PVDF printed parts is experimentally assessed by Tensile and Compression tests. Considering nozzle and bed temperature, infill percentage, printed part integrity, appearance, power, print time, and dimensional accuracy, the best parameters for PVDF are suggested. Various printing parameters were assessed to determine a set of viable options for fabricating PVDF (Kynar) objects of consistent dimensions. The mechanical response and microstructure of PVDF structures printed under the recommended conditions were investigated and reported in relation to mechanical tests.
