Invar Fe36Ni parts are produced by the “solvent on granule” 3D-Printing technique. Both elementary and prealloyed powders are used. A special purpose tabletopmachine, designed and built in a previous development, is used to print green parts, which are subsequently debinded and sintered in a muffle furnace. Prismatic specimens for thermal expansion tests and metallographicobservation are produced. In addition, benchmark parts are printed to test dimensional accuracy and shape preservation. The results show the feasibility of producing low thermal expansion coefficient material, which matches the target value of 1ppm/°Creported for the wrought alloy.
