A process of making a three-dimensional object includes providing a layer of powder material (310) and selectively depositing bonding inhibitor (320) on selected areas of the layer of powder material (310). The areas to be deposited with the bonding inhibitor (320) are selected according to a cross-section design of the three-dimensional object. The process also includes promoting bonding of the uninhibited areas of the entire layer of powder material (310) by either sintering or bulk deposition of chemical binders. The process further includes repeating the steps of providing a layer of powder material (310), selectively depositing bonding inhibitor (320) and promoting bonding until the three-dimensional object is formed. |
