Method and apparatus for fabricating three-dimensional object

A three-dimensional fabrication apparatus comprising:

• a fabrication chamber in which powder is layered to form a powder layer, the powder of the powder layer is bonded together in a desired shape to form a layered fabrication object, and another layered fabrication object is laminated on the layered fabrication object;
• a liquid discharge device configured to discharge a fabrication liquid onto the powder in the fabrication chamber;
• a vibration applicator configured to apply vibration to the powder layer onto which the fabrication liquid is discharged from the liquid discharge device;
• and
• a controller configured to control the liquid discharge device to discharge the fabrication liquid onto the powder in the fabrication chamber and configured to control the vibration applicator to apply vibration to the powder layer when the liquid discharge device discharges the fabrication liquid onto the powder layer to form the layered fabrication object,
• wherein the controller is configured to drive the vibration applicator prior to a start of the liquid discharge device discharging the fabrication liquid onto the powder layer to form the layered fabrication object and after an end of the liquid discharge device discharging the fabrication liquid,
• wherein the controller is configured to drive the vibration applicator during a period from a start to an end of formation of the layered fabrication object in a single layer of the powder layer, and
• wherein the controller is configured to drive the vibration applicator for a time period after the end of the liquid discharge device discharging the fabrication liquid, the time period being based on a viscosity of the discharging liquid.
