Abstract
A three-dimensional fabrication apparatus includes a fabrication chamber, a liquid discharge device, a vibration applicator, and a controller. In the fabrication chamber, 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. The liquid discharge device discharges a fabrication liquid onto the powder in the fabrication chamber. The vibration applicator applies vibration to the powder layer onto which the fabrication liquid is discharged from the liquid discharge device. The controller controls and drives 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.
