Summary: Aluminium composites with different wt% SiC reinforcements were synthesized through an ultrasonically assisted stir casting method. Ultrasonication was used to refine the grain size and achieve uniform dispersion of nano-SiC in the aluminium matrix. The mechanical properties of the composites were significantly enhanced, with the maximum hardness and ultimate tensile strength observed in the 1.5 wt% SiC reinforced composite. However, a decrease in mechanical properties was observed in the 2.0 wt% SiC reinforced composite due to the generation of brittle agglomerations.

Summary: This article used fused deposition modeling (FDM) and gas-pressure infiltration to make alumina/AlSi12 composites. Porous ceramic skeletons were created using FDM 3D printing with two different alumina powder-filled filaments. After solvent and heat debinding, the materials were sintered at 1500°C. The resulting porous alumina ceramic samples had no residual carbon content and were infiltrated with liquid metal for better mechanical properties.

Summary: This study aimed to characterize the adhesion performance of single-lap joints between aluminium and a polymer-based material manufactured by fused filament fabrication. Mechanical tension loading tests were performed and the fractured surface of the joints was analyzed to correlate the adhesion performance with the failure mode. The results showed that surface roughness, remelting of the primer, and stiffness of the polymer-based adherent have an impact on the mechanical properties of the joints.

Summary: Rapid investment casting is a cost-effective and time-saving process for manufacturing complex geometries. However, the surface roughness and dimensional tolerances of castings can be negatively affected by stair-stepping, poor burnout characteristics, and ash residue of 3D printed patterns. This study investigates the effects of burnout temperature and stair-stepping on surface roughness and tolerances by using 3D printed patterns made from different materials. The results show that the surface roughness is evenly distributed for all face angles and burnout temperatures, with an average value of 5 μm. PVB-derived castings retain the original surface texture better than ABS, and ABS patterns exert the highest thermal expansion stress on the ceramic shell.

Summary: Recent studies have explored the use of 3D-printed thermoplastic composite-based strips with self-expansion and contraction capabilities as a solution for addressing crack propagation in heritage structures. However, there is little information on the use of debris-reinforced PVDF composite as a repair and maintenance solution for such structures, followed by health monitoring of repaired cracks using IoT-based Bluetooth application. The debris-reinforced PVDF matrix composite, collected from the same site, can serve as a sensor to detect crack propagation due to weathering and seismic movements. The study found that the tri-hexagonal infill pattern had suitable mechanical, piezoelectric, thermal, and sensing capabilities for monitoring the health of repaired cracks.

Summary: This study reports the fabrication of wearable sensors by 3D printing thermoplastic polyurethane on woven fabric. The rheological, mechanical, voltage resistance (V-R), radio frequency (RF), and 4D capabilities of the printed substrate were evaluated. The research found that the RF characteristics of the sensors varied with different infill densities, and the change in resonating frequency under strain led to a change in dielectric constant and loss tangent.
