Abstract:
A method of generating a three-dimensional object onto a receiver surface by ablation transfer, the method comprising the steps of:a. representing the object as a three-dimensional image comprising a plurality of layers, each layer comprising an array of object positions arranged along first and second dimensions, the layers being contiguous along a third dimension;b. providing a transfer carrier comprising first and second opposed surfaces and, on the first surface, a polymeric transfer material, irradiation of the transfer carrier by transfer radiation through the second surface causing ablative ejection of the transfer material from the carrier onto the receiver surface, the receiver surface and the transfer material being separated by a separation distance;c. depositing a first layer onto the receiver surface by irradiating the transfer carrier in a pattern corresponding to a first layer of the three-dimensional image; andd. depositing at least five additional layers by augmenting the separation distance and irradiating the transfer carrier in patterns corresponding to the additional layers of the three-dimensional image, each successive layer being deposited onto the previous layer.
