N2 - Material extrusion additive manufacturing can be used for producing metal specimens when combined with debinding and sintering, similar to metal injection moulding. A highly-filled polymeric filament containing 55 vol% of 17-4PH stainless steel powder was prepared and used to print dog-bone specimens. Printed specimens were debound and sintered to obtain metallic specimens. The tensile properties were investigated. The average Young’s modulus was determined to be 196 GPa, the average maximum stress was 696 MPa and the strain at break 4%. Adequate cohesion between layers during material extrusion additive manufacturing is crucial for improving the mechanical properties of sintered specimens.
