Fused filament fabrication (FFF) combined with debinding and sintering could be an economical process for 3D printing of metal parts. In this study, compounding, filament making and FFF processing of a feedstock material containing 55 vol. % of 17-4PH stainless steel powder and a multicomponent binder system are presented. For the FFF process, processing windows of the most significant parameters, such as range of extrusion temperatures (210 to 260 °C), flow rate multipliers (150 to 200 %), and 3D printing speed multipliers (60 to 100 %) were determined for a constant printing bed temperature of 60 °C.
