Patent attributes
A three-dimensional forming apparatus includes: a stage; a material supply mechanism that supplies a sintered material in which metal powder and a binder are kneaded to a stage; a drying mechanism that dries the sintered material supplied from the material supply mechanism to the stage to form a dry sintered material; an energy radiation mechanism that supplies energy capable of sintering the dry sintered material; and a driving mechanism that is able to three-dimensionally move the material supply mechanism, the drying mechanism, and the energy radiation mechanism relative to the stage. The material supply mechanism includes a material ejection unit supplying a predetermined amount of the sintered material in a gravity direction. The energy radiation mechanism includes an energy radiation unit outputting the energy. The material ejection unit and the energy radiation unit are held in one holding mechanism.
