The research question seeks to identify FDM parameters that most strongly influence adhesion strength and microstructural porosity in PLA–cork laminated structures. Cork, a lightweight, elastic, and sustainable material, was selected as a novel substrate for functional, laminated structures. A Taguchi L36 fractional factorial design was employed to systematically evaluate six process parameters—build orientation, infill density, layer height, printing speed, contour lines, and bed temperature—and their effects on adhesion and porosity. Mechanical shear tests revealed a maximum adhesion strength of 1.39 N/mm under optimal conditions. Taguchi analysis indicated build orientation and infill density to be the most influential factors (delta = 0.2591 and 0.2484, respectively). Microstructural analysis showed that increasing infill density and adding contour lines reduced total porosity from ∼25 % to ∼13 %, enhancing interfacial bonding. Regression and signal-to-noise analyses quantifying the synergistic effects of key parameters, providing a predictive framework for optimizing adhesion. The findings demonstrate the value of integrating FDM technology with natural cork to produce sustainable, high-performance laminated structures.

The framework is applied to four representative adherend configurations: Al–Al, Al–GFRP, GFRP–GFRP, and Steel–GFRP, under both single and bi-adhesive layouts. Introducing a moderately ductile adhesive at the overlap ends increases ultimate load by approximately 67 % (Al–Al), 153 % (Al–GFRP), 265 % (GFRP–GFRP), and 103 % (Steel–GFRP) relative to a uniform single-adhesive baseline. Stress analyses indicate delayed edge yielding, 2–4 mm inward shifts of transfer zones, and 40–80 % higher mid-span shear plateaus. Overall, the attainable benefit is governed not by adhesive layout alone but by the stress-redistribution capacity of the adherends, being greatest for compliant–compliant pairs, least for rigid–rigid, and intermediate for asymmetric systems.

The main goal of this research deals with a new greener and more efficient nanolignin modification method to optimize its structural performance as a scavenger in urea-formaldehyde resin. For this reason, nanolignin was modified by L-lysine (an amino acid)/glycerol-based deep eutectic solvent (AADES) which then was used as scavenger in UF resin. Flexural modulus, flexural strength, internal bonding (IB), thickness swelling, and water absorption of the boards were measured. Also changes in formaldehyde emission were determined by the desiccator method. Based on the results of FTIR and DSC analysis, the addition of AADES-modified nanolignin improved cross-linking, and accelerated it with the resin curing temperature. The mechanical and physical properties of the boards were also improved by adding AADES-modified nanolignin. The particleboard panels made with modified nanolignin have significantly lower formaldehyde emission than the boards that contain just nanolignin and the boards made with pure UF resin, respectively. Adding modified nanolignin at three levels of 1, 2, and 3 % reduced formaldehyde emission by 21, 29, and 38 % compared to the UF control sample the panels reaching a level lower than the E1 standard requirements. Based on the results of this research, the NH₂ groups of the amino acid on the surface of modified nanolignin can increase the reactive sites of nanolignin and play an important role in the results obtained.
