摘要： A method for fabricating an object includes forming, first applying, second applying, and repeating. The forming forms a powder layer. The first applying applies a droplet containing a radiation absorber to the powder layer. The second applying applies radiant energy to the powder layer. The repeating repeats the forming, the first applying, and the second applying. The first applying includes applying the droplet to a surface of the powder layer to form a fabrication region; dividing the fabrication region into a plurality of divided regions; and applying the droplet a plurality of times to a partial specific divided region among the plurality of divided regions. The second applying includes applying the radiant energy with a variable radiation intensity to a range including at least the specific divided region.

摘要： A three-dimensional fabricating apparatus includes a fabrication chamber, a flattening member, a surplus powder chamber, and an impact applicator. The fabrication chamber stacks powder in layers and a layered fabrication object in which the powder is bonded together. The flattening member relatively moves with respect to the fabrication chamber to fill the fabrication chamber with the powder. The surplus powder chamber is disposed outside the fabrication chamber, to receive a surplus of the powder having not been filled in the fabrication chamber. The impact applicator is movable with the flattening member to contact and impact on the surplus powder chamber.

摘要： A three-dimensional fabricating apparatus includes a fabrication stage, a rotator, a powder remover, and a cleaning controller. Fabrication layers including powder bonded together are to be laminated on the fabrication stage. The rotator rotates and moves relatively with respect to the fabrication stage in a direction along a stage surface of the fabrication stage to flatten a surface of the powder on the fabrication stage and form a powder layer. The powder remover contacts a circumferential surface of the rotator and removes the powder adhering to the circumferential surface of the rotator. The cleaning controller is operatively connected to the rotator to control a cleaning operation to rotate the rotator and clean the powder accumulated between the circumferential surface of the rotator and the powder remover.

摘要： An apparatus for fabricating a three-dimensional object includes a fabrication stage and a flattener. A fabrication layer in which powder particles are bound together is formed layer-by-layer on the fabrication stage. The flattener relatively moves in a moving direction along a stage surface of the fabrication stage and flattens a surface of powder on the fabrication stage to form a powder layer. The fabrication stage and the flattener are arranged to be relatively movable in a height direction. In formation of the powder layer on the fabrication layer formed on the fabrication stage, the apparatus performs an operation to increase a distance between the flattener and the fabrication stage in the height direction when the flattener moves to a position near an edge of the fabrication layer in the moving direction.
