Abstract Adhesively bonded joints play a vital role in improving the structural performance of 3D‐printed components. This research aims to examine effect graphene inclusion on failure load and vibrational behavior polylactic acid flat‐joggle‐flat (FJF) prepared using fused deposition modeling. The present focused print directions (0°, 45°, 90°) nanofiller (0.25, 0.50, 0.75, 1.00 wt%) FJF joints. raster direction mechanical properties was examined by tensile testing dog‐bone samples. Results showed that 0° orientation had higher strength compared other printing directions. Shear indicated has enhanced 61.18%. Fractography results formation shear band with 0.50 wt% helps distribute stress more evenly prevent catastrophic joint. free test revealed improved natural frequencies, as presence graphene‐enhanced interfacial bonding between adherend adhesive. Highlights than Inclusion delayed graphene‐reinforced reinforced failure. joint added 1.0 lower frequencies.

This research aims to use energy harvested from conductive materials power microelectronic components. The proposed method involves using vibration-based harvesting increase the natural vibration frequency, reduce need for battery replacement, and minimise chemical waste. Piezoelectric transduction, known its high-power density ease of application, has garnered significant attention. Additionally, graphene, a non-piezoelectric material, exhibits good piezoelectric properties. explores novel printing graphene material 3D printing, specifically Direct Ink Writing (DIW) fused deposition modelling (FDM). Both simulation experimental techniques were used analyse harvesting. technique involved cantilever beam-based method. results showed that DIW-derived 3D-printed prototype achieved peak output 12.2 µW, surpassing 6.4 µW FDM-derived prototype. Furthermore, COMSOL Multiphysics yielded 0.69 µV.
