Abstract: A process for building three-dimensional objects based on electrophotographic printing is disclosed, comprising the steps of depositing a first layer of powdered base material on a substrate, operating an imaging member, a charging device, an image generating device and an image developing device, in that order, to deliver and deposit filler material onto the layer of powdered base material in an image-wise manner to produce a layer of bonded base material that correspond to the first cross-section of the three-dimensional object being built, repeating all the above steps for as many times as required to form successive layers that constitute the three-dimensional object, said filler material further causing adjacent layers to be bonded with one another; and removing unbonded material to cause the three-dimensional object to appear.
