Special Issue Information

Dear Colleagues,

The full range of uses for symmetry in material structuring by additive manufacturing (AM) processes has not yet been discovered in terms of its potential in driving the performance of designed parts. According to an optimized selection of AM process parameters for a wide variety of materials, we can expect to see tremendous effect on the mechanical, thermal and transfer properties . Each of the AM process has a different way in tuning the material structure according to discontinuities that are created during the process of layer-by-layer building. This Special Issue focuses on the link between the material symmetry / asymmetry generated by AM processes and the achieved performance. This Special Issue welcome both numerical and experimental technical papers, as well as review contributions. We hope that this Issue will provide an opportunity to share the most recent advances in AM and contribute to further unveiling the potential of AM processes in order to tune the material performance at scales of different length while understanding the implications of material symmetry in AM processes.

This study aims to relate the microstructural arrangement, in particular the symmetry materialized by filament sequencing in the fused filament fabrication process, to the mechanical behavior of printed polyamide. Dog-bone structures were printed using various printing temperatures ranging from 250 °C to 280 °C, which were combined with part orientation including vertical, horizontal, and lateral configurations and raster angles (0°, 15°, 30°, and 45°) that represent the in-plane and out-of-plane symmetrical arrangement of the filament. Mechanical testing was conducted on both as-received filaments and printed structures to derive the effects of filament arrangement symmetry and process-generated defects on mechanical loss. In addition, a microstructural analysis using scanning electron microscopy was used to share more light on the filament arrangements and their consequence on the deformation mechanisms with respect to the printing conditions. The results showed that the 3D printed polyamide-based materials exhibited remarkable tensile performance with strain stiffening behavior and large elongation at break due to their particular filament layout. Among the considered printing conditions, the part orientation was found to have the largest influence on the tensile behavior, which modulates the behavior from complete restoration of the filament performance to mechanical loss.
