Abstract

In this study, the effect of nozzle temperature, (Tn) (varied between 200°C and 300°C) during the printing stage on the relative density, hardness, and porosity of sintered Inconel 718 (IN 718) specimens are investigated for the first time. The results show a general trend of increasing relative density and hardness values, as well as reduced porosity with an increase in Tn values. The highest relative density (92.34%), hardness (188 HV) and lowest porosity (7.66%) are all achieved at Tn=290°C. The outcomes of this study establish the profound impact of adjusting processing parameters even at the initial printing stage towards the properties of the sintered parts.
