摘要

This study investigates the optimization of nanoclay coating on PLA filaments for Fused Filament Fabrication (FFF) applications. The research examines the effects of key process parameters including dwell time, nanoclay content, and solution temperature on coating thickness and mechanical properties. Experiments confirmed that coating thickness increased with higher dwell times and higher nanoclay concentrations, while elevated solution temperatures reduced layer thickness. Carefully adjusting the process parameters, the coating thickness was controlled between 20 and 50 µm. Following the coating process, the filaments underwent mechanical testing, demonstrating significant improvements in compressive strength almost 26% at 3% by wt of nanoclay in PLA.
