Summary: AlSi10Mg-based nanocomposites with the addition of 1 wt% Gd2O3 and Er2O3 nanoparticles were successfully fabricated using LPBF additive manufacturing. Remelting the printed layers was found to improve the densification of the samples. The microstructural observations and XRD patterns confirmed the formation of coarsened clusters and interfacial intermetallic layers between the nanoparticles and the aluminum matrix. Measurement results of grain size and microhardness showed that the addition of Er2O3 played a more effective role in grain refinement and hardness enhancement compared to Gd2O3.

Summary: Additive manufacturing, also known as 3D printing, can create complex structures that traditional methods cannot. However, current multi-material 3D printing techniques lack accuracy for small-scale property control, making it difficult to print highly anisotropic structures at a small scale. This study proposes a method using grayscale vat photopolymerization to 3D print locally tunable anisotropic patterns, allowing for flexible adjustment of the degree and orientation of anisotropy. This method only requires one resin feedstock, preserving the accuracy and efficiency of vat photopolymerization printing.

Summary: Reactive extrusion additive manufacturing (REAM) is a process that combines and deposits multi-part thermoset resin to create layered parts with motion-controlled nozzle. By mixing different resins, it is possible to customize the material structure and resulting properties of the parts. This research focuses on a two-part shape memory polymer with magneto-active iron oxide particles added, and investigates the effect of functional grading on the magneto-active properties of the shape memory polymer. Analytical models are derived to predict the magnetic field-responsive behavior of the thermoset composites.

Summary: Friction stir additive manufacturing (FSAM) is used to fabricate nanoparticle reinforced aluminum matrix composites, optimizing material properties in terms of hardness and grain size. The dispersion of nanoparticles increases hardness and reduces grain size, while re-stirring and reheating in the stirring zone improves mechanical properties. Both nanoparticle size and volume fraction have significant effects on grain size and hardness.
