ABSTRACT:
A three-dimensional object is generated according to a stored, digital representation through layer-by-layer transfer of material onto a receiver, each layer corresponding to a layer of the three-dimensional representation. Each deposited layer is applied through selective irradiation of an ablation-transfer carrier. The carrier includes a transfer material that is ejected in response to irradiation, and which solidifies on the receiver or on a previously applied layer of transfer material. Thus, irradiation of the carrier in an area pattern corresponding to a layer results in deposition of the transfer material in accordance with the pattern. Sequential irradiations of fresh ablation-transfer carrier material, each according to a two-dimensional pattern corresponding to one of the contiguous layers of the three-dimensional object, result in depositions that gradually build up into the three-dimensional object.
