INFLUENCE OF FUSED FILAMENT FABRICATION PARAMETERS ON TENSILE PROPERTIES OF POLYLACTIDE/LAYERED SILICATE NANOCOMPOSITE USING RESPONSE SURFACE METHODOLOGY
Abstract
This study aimed at assessing and optimising the influence of printing speed and extrusion temperature in a fused filament fabrication (FFF) process on the tensile properties of a polylactide/layered silicate nanocomposite. Mathematical models using Doehlert designs were formulated to examine factor and interaction effects. The models were corroborated by measurements using capillary rheology, tomographic images, and crystallinity analyses to find physical explanations for the differences in tensile properties. The tensile properties were a non-monotonic function of printing speed, which may be due to various deposition defects that influence the porosity of composite tensile specimens. This study provides new insights into FFF process optimisation regarding rheological behaviour and mesostructure of nanocomposite by highlighting new modes of deposition defects that originate from process parameter settings and materials. The results contribute to the properties mastery of FFF-processed materials.
