Abstract
Material extrusion (MEX) is a form of additive manufacturing that has become extremely popular in recent years due to its affordability and the simplicity of the equipment used. MEX can be used to create metal 3D parts by printing with a polymer binder and metal powder feedstock based on a 3D model, then using debinding and sintering to post-process the part. With advances in material development, material extrusion is expected to be used extensively in developing a wide range of functional parts designed by topology optimization and with lattice structures. In this article, we describe important aspects of material extrusion, including feedstock, equipment, materials, 3D printing, debinding, and sintering, along with the physical properties of sintered parts.
