Summary:Filament material is an important factor to be considered in the product development by 3D printing, since it can affect not only the quality but also the functionality of the printed parts. Thus, the objective of this paper is to investigate how feasible would be to use low- and high-density polyethylene to fabricate 3D printing filaments. Since the extrusion process depends on the rheological behavior of the polymers, first, the melt viscosity of LDPE and HDPE was analyzed by capillary rheology. Then, LDPE and HDPE filaments of 1.75 mm diameter were extruded under different processing conditions and subjected to tensile tests to determine the mechanical properties. Results showed that the LDPE and HDPE are suitable for manufacturing 3D printing filaments if the extrusion processing conditions are optimized.
