Recently, the material extrusion (MEX) method, known for its straightforward and economical setup, has become a focal point in metal additive manufacturing. MEX enables the fabrication of precise 3D models by molding metal powders with resin, followed by debinding and sintering processes. Through material development, this method is expected to become more extensively applied for the development of various functional parts by materials and shape designated using topology optimization and lattice structures. This review covers the MEX process, including feedstock, equipment, materials, printing, debinding, sintering, and the physical properties of sintered parts.
