Abstract:
1. A method of printing comprising the steps of: providing a solid state material having an exposed surface; applying an auxiliary layer comprising a polymer to the exposed surface to form a composite structure; subjecting the composite structure to conditions inducing a stress pattern in the auxiliary layer and in the solid state material by setting up a pre-defined temperature distribution profile inside the auxiliary layer, with a glass transition temperature of the polymer being between minimum and maximum temperatures of the temperature distribution profile, such that a part of the auxiliary layer tempered to a temperature below the glass transition temperature of the polymer is stiffer than another part of the auxiliary layer tempered to a temperature above the glass transition temperature, thereby facilitating fracture of the solid state material substantially along a plane at a depth therein, wherein the glass transition temperature of the polymer is below room temperature; and removing the auxiliary layer and, therewith, a layer of the solid state material terminating at the fracture depth, an exposed surface of the removed layer of solid state material having a surface topology corresponding to the stress pattern.
