Abstract
Embodiments of the invention are directed to a system and method to fabricate three-dimensional objects, layer by layer, by selectively dispensing material from a printing head onto a transfer platform to form a cross-sectional layer of the object that has a pre-determined non-uniform surface. Each layer may then be transferred from the transfer platform to previously formed layers that are carried by a fabrication platform by contacting an exposed surface of a previously formed layer to the layer on the transfer platform.
