Abstract
In-situ foam 3D printing offers a promising route to improve interlayer adhesion in FDM parts by exploiting expansion during extrusion. This study investigates the effect of nozzle diameter on the foaming behavior, cell structure, and mechanical performance of PLA-based foamable filaments. Three nozzle diameters (0.4, 0.6, and 0.8 mm) were tested across different temperatures, and the resulting cellular structure, flexural and impact properties were evaluated. Results show that smaller nozzles promote finer cell structures due to increased shear and residence time, which also enhance mechanical performance through improved adhesion between deposited layer.
