Özet
Thermoplastic composite filament materials can be used in the manufacturing method with melted filament, which is among the additive manufacturing methods. Thermoplastic composite filament materials allow obtaining different thermal, chemical, mechanical and surface properties. In this study, PLA filament and PLA-Steel filament materials with approximately 80% by weight of 410L steel powder were compared in terms of impact strength, tensile strength and thermal conductivity properties. As a result of the experiments carried out, the highest impact strength was measured at 14.27 kJ/m2, the highest tensile strength was 41.62 MPa and the highest thermal conductivity was 0.1364 W/mK for PLA material. The highest impact strength was measured at 11.51 kJ/m2, the highest tensile strength was 19.06 MPa and the highest thermal conductivity was 0.2758 W/mK for the steel powder added PLA material. Thus, the impact and tensile strength value of PLA material decreased and the thermal conductivity value increased with the addition of steel powder. Different levels of filling ratio, printing temperature, printing speed and layer thickness printing parameters were used in the production of test specimens. The effects of these pressure parameters on the impact and tensile strength values were investigated. The effects of printing parameters were revealed by the results of ANOVA analysis. In addition, the microstructure of the materials was investigated by scanning electron microscopy.
