Abstract

In 3-D printing a platen moves toward an intermediate transfer belt (ITB) to have a sheet positioned on the platen contact the ITB to electrostatically transfer a layer of different materials to the sheet, and then the platen moves to a heater to join the layer to the sheet. This processing is repeated to have the sheet repeatedly contact the ITB (with intervening heating at the heater) to successively form layers of the materials on the sheet. The sheet having the layers thereon moves to a rinsing station, where a liquid is applied to dissolve the sheet and leave a freestanding stack of the layers. The freestanding stack is fed to a platform to successively form a 3-D structure of freestanding stacks of the layers. Light and/or heat are applied to the 3-D structure to bond the freestanding stacks to one another on the platform.
