Abstract The scope of 3D printing is limited by its maximum area, necessitating joints for assembling larger structural elements. Natural fibers have been employed to reinforce printed materials, enhance their mechanical properties, and reduce polymer usage. However, the effects these on bonded joints, particularly in context continuous natural yarns, remain underexplored literature. This study investigates behavior 3D‐printed single‐lap (SLJ) with biocomposite adherends, using Fused Filament Fabrication (FFF). Continuous Jute Fiber Reinforced Polymer (JFRP) Polylactic Acid (PLA) were used fabricate adherends. Mechanical characterization, including surface roughness analysis shear tests, was performed PLA‐PLA, JFRP‐JFRP, JFRP‐steel, JFRP‐wood joints. Results show that addition jute mono‐material increased failure load 66.53% compared neat PLA‐PLA due a 47.20% increase roughness. Polymer‐wood demonstrated best performance, achieving 2543.76N, 56.85% higher than JFRP‐JFRP indicating potential mixed‐material, sustainable structures. Analytical models applied assess distribution along adhesive. Highlights yarn improves composite behavior, reducing brittle failure. mode toughness raises SLJ 66.53%, enhancing contact area. Analyses parts wood steel. Bi‐material better results rigidity.
