Effect of chemical treatment of sugar palm fibre on rheological and thermal properties of the PLA composites filament for FDM 3D printing

The thermal and rheological properties of bio-composite filament materials are crucial characteristics in the development of a bio-composite Fused Deposition Modeling (FDM) filament since the printing mechanism of FDM strongly depends on the heating and extrusion process. The effect of chemical trea...
