The primary goal of this investigation is to contrast two different polyamide composite mixes with creative thermal properties in terms of their morphological and thermal characteristics. The two separate polyamide composite mixes extruded in the form of wire by twin screw extrusion are polyamide-6 (PA6) reinforced with 5, 15 and 25 weight percent glass fibre (GF) and PA6 reinforced with 5, 15 and 25 weight percent glass beads (GB). The experimental study demonstrates how to print the specimens using a three-dimensional (3D) printer that is based on Fusion Deposition Modeling (FDM). The responses of composites, including their morphology, Thermal Conductivity (TC), and Heat Distortion Temperature (HDT), were evaluated. The findings contrast the growing TC and HDT thermal characteristics of the 3D-printed specimen with the increase in bead content over the course of the study. The PA6 matrix's thermal characteristics are enhanced by the GB, a crystalline material, while the PA6 matrix's high modulus is provided by the GF, a dimensionally stable material. In comparison to neat PA6 matrix reinforced with 05, 15, and 25 wt.% GF, it was found that neat PA6 matrix reinforced with 05, 15, and 25 wt.% GB had much higher thermal properties. The thermal characteristics of PA6+25% GB are improved, and this could provide new opportunities for industrial uses such electrical, aerospace, and automotive components.
