[16P-T7-03] Development of the Binder Jetting Technology for Aeronautic Applications: State of the Art and Focus on IN718 Alloy
Keywords:Metal Binder Jetting , INCO718, additive manufacturing, sintering, safety
This study aims at presenting the current status of the IN718 development using Binder Jetting at Safran and the challenges associated with its industrialization for aeronautic applications. Printing tests done on several laboratory/production machines, with powders from different suppliers and with different particle size distributions will be used to exemplify the impact of such parameters on the part quality at each stage, from printing to sintering. A study of part density, sintering, reproducibility has been performed. Based on these findings, a map of influent parameters will be shared to elucidate the path towards industrialization and certification of parts in the aeronautic field. Perspectives will be given regarding the common framework to be developed for the Binder Jetting to become the cost efficient and high material quality process it could be.
