Optimization of printing parameters of 3D-printed continuous glass fiber reinforced polylactic acid composites

Abstract A novel 3D printing strategy for continuous glass fiber reinforced polylactic acid (CGF/PLA) composites was proposed. CGF/PLA filament was prepared by a melting impregnation device, and then CGF/PLA filament was directly supplied to the self-modified 3D printing device. The impregnation process was optimized systematically, and the fiber content reached up to 45 wt%. A specific compatibilizer was used and the amount of compatibilizer was optimized to enhance the interfacial bonding between fiber and polymer. The effects of printing parameters such as nozzle diameter, edge width, layer thickness, printing speed and temperature on the mechanical properties and microstructure of the final printed products were studied. The flexural strength and flexural modulus of the printed products reached 312 MPa and 21.5 GPa, respectively. The fabrication strategies proposed in this study can provide a low-cost and high-strength method for the industrial application of 3D printed continuous fiber reinforced thermoplastic composites.

Highlights 3D printing of continuous glass fiber reinforced polylactic acid composites with a high efficiency and low cost strategy. The printed composites exhibited great flexural strength and fiber content up to 45 wt%. Impregnation and Printing Parameters were optimized to provide a foundation for future industrial application.
