In FDM technology, which is performed by extruding a material from a heated nozzle using an MIM material, generally uses a resin material as a binder. This process requires degreasing and sintering steps to remove a binder after molding. The degreasing process is carried out in a dedicated apparatus using an organic solvent. In this study, using agar as a binder, it was possible to carry out degreasing and sintering processes continuously in the same furnace. In this report, the effect of material mixing ratio of metal powder, agar, and water on the density and hardness of shapes was clarified.
