Summary: Designing products with elastic properties is a crucial task for engineers, as the material properties play a significant role in defining the functionality of the product. Using Fused Filament Fabrication (FFF) to print products in thermoplastic polyurethanes (TPU) allows for the design of elastic products with a variety of forms and elastic properties. Internal structures and variations in thickness can be utilized to create products with different elastic characteristics. The study also investigates the influence of internal density variation on product elasticity, with a case study on a fully elastic 3D-printed keyboard. The results show that elasticity can be affected by orientation, geometry, and internal lightening, providing insights for designing products with specific properties.

Summary: The study found that unique and original designs had lower scores in their AM suitability, solutions with higher complexity scored higher on usefulness and overall creativity, and solutions with higher complexity had higher build cost, build time, and material usage. These findings highlight the importance of considering both opportunistic and restrictive DfAM when evaluating solutions designed for AM. Balancing these two perspectives can support the development of creative solutions that consume fewer build resources.

Summary: In this study, a self-developed ML-PBF equipment was used to produce SS316L samples. The dimensional accuracy, microstructure, defects, surface roughness, and mechanical properties of single-laser PBF samples, dual-laser PBF samples, and quad-laser PBF samples were investigated using a new scan strategy called variable area scan. It was found that the single-laser and quad-laser samples had good surface quality and dimensional accuracy, while the size of the double laser printed samples deviated due to stitching error. Moreover, the number of lasers affected the grain size and preferred orientation of the overlapping region.

Summary: The aim of this study is to investigate the control of mechanical properties and functional properties of NiTi alloy through selective laser melting (SLM). X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscopy and tensile testing methods were used to study the effects of different laser power and scanning speed on the densification behavior, phase transformation characteristics and mechanical properties of NiTi alloy. The study found that the variation of the keyhole effect caused by scanning speed has a greater effect on the densification behavior of SLM NiTi alloy compared to laser power. The increase in scanning speed weakens the burning degree of Ni element, leading to a decrease in phase transition temperature.

Summary: This study investigated the printability, microstructure, and mechanical properties of Zr-4 alloy additively manufactured by laser powder bed fusion (LPBF) for the first time. The optimized printing parameters resulted in a Zr-4 alloy with a high relative density of 99.77%. Increasing the annealing temperature led to a microstructural change in the alloy, resulting in a high compressive strength of 2130 MPa and compressive strain of 36%. Precipitation of Zr (x) (Fe2Cr) compounds at annealing temperatures exceeding 700 degrees C strengthened the alloy by pinning effect. These findings provide valuable guidance for the manufacture of geometrically complex Zr alloy parts for nuclear power applications.

Summary: In this study, monitoring and denoising of melt pool radiation in laser powder bed fusion (LPBF) is conducted. By using photodiodes and semiconductor cameras, coaxial radiation signals and images of melt pools are captured. The temperature of the melt pool increases with laser input energy and the fluctuations of radiation signals caused by spatter intensify. To improve the accuracy of melt pool temperature and enhance the behavior features, the variational mode decomposition (VMD) method is employed to obtain radiation signal components associated with the melt pool region or non-melt pool region.
