Mechanical Behavior Prediction of 3D‐Printed PLA/Wood Composites Using Artificial Neural Network and Fuzzy Logic

Polymers for Advanced Technologies, Journal Year: 2025, Volume and Issue: 36(2)

Published: Feb. 1, 2025

ABSTRACT This study presents a novel approach to optimize and predict the mechanical properties of 3D‐printed polylactic acid (PLA)/wood composites through artificial neural network (ANN) fuzzy logic (FL) modeling. The research addresses critical challenge determining optimal process parameters in fused deposition modeling (FDM) natural fiber composites. Using Taguchi's L27 orthogonal array, experiments were conducted with five key printing parameters: layer thickness (100–200–300 μm), speed (PS) (40–60–90 mm/s), raster angle (RA) (0°–45°–90°), infill density (ID) (30%–60%–90%), nozzle temperature (NT) (190°C–200°C–210°C). Analysis revealed that RA PS most influential parameters, contributing 41.86% 40.92% tensile compressive strengths, respectively. developed ANN model demonstrated exceptional prediction accuracy R 2 values 99.94% for both surpassing FL model's performance ( = 97.16%). development these models is crucial accurately predicting behavior, allowing efficient optimization without extensive physical testing. Both methods high accuracy. Validation tests maximum errors 1.95% 2.81% FL, findings contribute valuable insights high‐performance establish foundation future advanced manufacturing processes.

Biodegradable Polymer Composites Based on Poly(butylene succinate) Copolyesters and Wood Flour

Polymers, Journal Year: 2025, Volume and Issue: 17(7), P. 883 - 883

Published: March 26, 2025

This study investigates the biodegradation behavior of poly(butylene succinate) (PBS) copolyesters containing dilinoleic acid (DLA) co-monomeric units and wood flour (WF) as a filler. PBS-DLA is segmented thermoplastic elastomer (TPE), where soft amorphous phase formed by DLA ester segments, while hard consists crystallizable PBS domains. Wood-plastic composites (WPCs) were prepared with WF at weight fractions 10%, 20%, 30%, 40% wt. analyzed in terms surface morphology, chemical structure, mechanical performance, thermal stability before after soil conditions. The results microscopic analysis confirmed that copolymer its undergo manifested increased roughness microcrack formation, particularly higher content. ATR FT-IR spectroscopy indicated oxidation hydrolysis, supporting hypothesis progressive erosion. Mechanical tests showed decline tensile strength elongation break, most pronounced changes 20% WF. Thermal (DSC, DMTA, TGA) retains elastomeric 3-month experiment. storage modulus (E') remained stable, only minor variations melting crystallization temperatures observed. These findings reinforce erosion rather than bulk degradation mechanism. Given their biodegradability retained behavior, WPC based on copolyester could be promising for eco-friendly applications controlled desirable, such packaging, agriculture, or biodegradable consumer goods.

Biomaterials, used here to signify 100% biobased and biodegradable materials, can offer a promising solution for transitioning away from fossil-based resources, addressing the climate crisis, combating plastic pollution. To ensure their environmental benefits, biomaterials must derive regenerative, non-polluting feedstocks that do not compete with food or feed production. From this perspective, agricultural residues by-products present favorable feedstock option Although is an improvement over sourcing them primary crops, sustainability of underlying systems be considered. Furthermore, nutrient value specific soil ecosystems often overlooked despite compostability.
