Improving thermomechanical properties of fused filament fabrication printed parts by using nanocomposites

This study aims to assess the viability of nanocomposites in fused filament fabrication. Polylactide/organo-modified layered silicate materials have been studied terms structure and properties evolution through whole manufacturing chain, for thermomechanical optimisation. The method included optimisation by composite formulation additive process experimental designs. A competition between flow thinning molten stiffness input with addition filler allows an enhanced printability at intermediate loadings. provides final parts, enabling similar or greater tensile properties, while providing better thermal stability, additively manufactured nanocomposite compared conventionally polymers.
