This review explores the impact of various additives on mechanical properties polylactic acid (PLA) filaments used in Fused Deposition Modeling (FDM) 3D printing. While PLA is favored for its biodegradability and ease use, inherent limitations strength heat resistance necessitate enhancements through additives. The natural synthetic fibers, inorganic particles, nanomaterials properties, printability, overall functionality composites was examined, indicating that fiber reinforcements, such as carbon glass significantly enhance tensile stiffness, while fibers contribute to sustainability but may compromise stability. Additionally, inclusion particulate fillers like calcium carbonate improves dimensional stability although larger particles can lead agglomeration issues. study highlights potential improved performance specific applications acknowledging need further investigation into optimal formulations processing conditions.

This study explores the structural performance and optimization of 3D-printed Polylactic Acid (PLA) lattice structures, focusing on octapeak, hexstar, dodecahedron designs, for potential load-bearing applications. Through compression testing, load-displacement behavior each structure type was analyzed, examining key characteristics such as peak load capacity, deformation patterns, failure modes. The Preference Ranking Organization Method Enrichment Evaluations (PROMETHEE) employed to assess configuration based two primary criteria: compressive strength mass. analysis yielded insights that were structure-type specific well overall across all nine samples. Among hexstar configurations, sample 4 attained highest rank due its exceptional making it optimal choice high-strength Within octapeak groups, samples 2 7, respectively, demonstrated balanced performance, suitable applications prioritizing mass efficiency over maximum strength. In ranking, emerged top-performing structure, with configurations consistently balancing effectively, while offered viable alternatives lighter, less load-intensive uses. findings demonstrate utility PROMETHEE method in optimizing engineering applications, thus contributing advancement sustainable design additive manufacturing. research provides a framework selecting structures meet application-specific criteria material efficiency.

Abstract Poly(vinylidene fluoride) (PVDF) is a piezoelectric and thermoplastic material with great potential for additive manufacturing (AM) applications. Using barium titanate (BaTiO 3 ) as filler, PVDF‐based composite materials were developed, characterized, processed by AM extrusion (MEX). The morphological features phase transformations occurring throughout the processing of BaTiO ‐filled PVDF, from compounding to printed part, analyzed. morphology powder feedstock after dispersion in high‐energy ball mill changed spheroidal laminar β‐phase formation was favored. Microhardness gradually increased content, obtaining an enhancement ~60% content 25 vol%, supported good filler. A ~48% increase dielectric permittivity also achieved. After extrusion, filaments filler 15 vol% showed more stable diameter, well higher crystallinity surface roughness, compared those lower contents. Material filament direct printing pellets based on MEX successfully used obtain parts. Composite parts enhanced hydrophilicity, flexural modulus (up ~33% 7 PVDF), thus leading superior mechanical characteristics biomedical Highlights Dry milling suitable greener approach. processes 3D‐printed use pellets/powder improved 3D printability. roughness hydrophilicity content. elastic
