Abstract
Official abstract text for this publication.
A three-dimensional forming apparatus includes: a stage; a material supply unit that supplies the stage with a sintered material including metal powder and a binder; a head unit that includes an energy radiation unit supplying energy capable of sintering the sintered material to the sintered material supplied by the material supply unit; a head base that holds a plurality of the head units; and a driving unit that is capable of three-dimensionally moving the head base relative to the stage.
First claim
Opening claim text (preview).
What is claimed is: 1 . A three-dimensional forming apparatus comprising: a stage; a material supply unit that supplies the stage with a sintered material including metal powder and a binder; a head unit that includes an energy radiation unit supplying energy capable of sintering the sintered material to the sintered material supplied by the material supply unit; a head base that holds a plurality of the head units; and a driving unit that is capable of three-dimensionally moving the head base relative to the stage. 2 . A three-dimensional forming apparatus comprising: a stage; a material supply unit that includes a material ejection unit supplying a sintered material including metal powder and a binder to the stage; an energy radiation unit that supplies energy capable of sintering the sintered material to the sintered material supplied by the material supply unit; a head base that holds a plurality of head units in which the material ejection unit and the energy radiation unit are held; and a driving unit that is capable of three-dimensionally moving the head base relative to the stage. 3 . The three-dimensional forming apparatus according to claim 2 , wherein of the plurality of material supply units, the material supply unit including the material ejection unit held in at least one of the head units accommodates the different sintered material from the other material supply units. 4 . The three-dimensional forming apparatus according to claim 1 , wherein the energy is a laser. 5 . The three-dimensional forming apparatus according to claim 2 , wherein the energy is a laser. 6 . A three-dimensional forming method comprising: supplying a stage with a sintered material including metal powder and a binder; forming a single layer by moving a head base that holds a plurality of head units including an energy radiation unit that supplies energy capable of sintering the sintered material relative to the stage, supplying the energy to the sintered material, and sintering the sintered material; and forming a second layer in the forming of the single layer by stacking the second layer on a first single layer formed in the forming of the single layer, wherein the forming of the second layer is repeated a predetermined number of times. 7 . A three-dimensional forming method comprising: forming a single layer, the forming of the single layer including ejecting a sintered material including metal powder and a binder from a material ejection unit to a stage by moving, relative to the stage, a head base that holds a plurality of head units holding the material ejection unit included in a material supply unit that supplies the sintered material to the stage and an energy radiation unit supplying energy capable of sintering the sintered material to the sintered material supplied by the material supply unit, and including supplying the energy to the sintered material ejected in the ejecting of the sintered material and sintering the sintered material; and forming a second single layer in the forming of the single layer by stacking the second single layer on the first single layer formed in the forming of the single layer, wherein the forming of the second layer is repeated a predetermined number of times. 8 . The three-dimensional forming method according to claim 7 , wherein of the plurality of material supply units, the material supply unit including the material ejection unit held in at least one of the head units accommodates the different sintered material from the other material supply units. 9 . The three-dimensional forming method according to claim 6 , wherein the energy is a laser. 10 . The three-dimensional forming method according to claim 7 , wherein the energy is a laser.
