Patent ID: 11045976

Abstract:
An apparatus for producing three-dimensional objects is provided including a bonding liquid applier and a controller. The bonding liquid applier applies a bonding liquid to a powder layer to form a bonded layer. The controller controls the bonding liquid applier to repeatedly form an (n)th bonded layer by applying a predetermined amount of the bonding liquid per unit area, in multiple times, to a new bonding region in an (n)th powder layer, below which an (n−1)th bonded layer does not exist, and applying the predetermined amount of the bonding liquid per unit area, in a smaller number of times than the multiple times, to an existing bonding region in the (n)th powder layer, below which the (n−1)th bonded layer exists, while increasing a numeral (n) representing an integer of 1 and above in increment of 1, to laminate multiple bonded layers into a three-dimensional object.
