Binder Jetting technology provides a new scope in metal additive manufacturing due to its capability to produce high complexity parts in a wide variety of different materials. This work opens a new pathway to fabricate high dimensional stability Invar36 aerospace devices with Binder Jetting technology for applications where temperature fluctuations directly interfere in the correct performance of high sensibility systems. Since full density part fabrication is one of the main ongoing challenges for Binder Jetting the leading objective of this work is to study and optimise the main process parameters to increase the final density of Invar36 printed parts. Microstructural analysis and obtained density and CTE values confirmed the feasibility to fabricate Invar36 parts.
