Abstract: A method for manufacturing, the method includes coupling a sample to a mount, and immersing at least part of the sample in a photosensitive liquid having an upper surface defining an interface between the photosensitive liquid and a surrounding environment. At least a polymer layer that is coupled to at least a section of the sample is formed by: setting a thickness of the polymer layer by controlling a position of the sample relative to the upper surface, and illuminating at least the upper surface so as to polymerize the photosensitive liquid to form the polymer layer.

Abstract: A method for circuit fabrication includes defining a locus of a conductive trace to be formed on a circuit substrate. Molten droplets of a metal are ejected from a donor substrate in proximity to the circuit substrate onto the defined locus by a process of laser-induced forward transfer (LIFT), whereby the droplets adhere to and harden on the circuit substrate along a length of the defined locus. After the droplets have hardened, a laser beam is directed toward the defined locus with sufficient energy to cause the metal in the hardened droplets to melt and coalesce into a bulk layer extending along the length of the defined locus.

Abstract: Printing apparatus includes a donor supply assembly, which positions a transparent donor substrate having opposing first and second surfaces and a donor film formed on the second surface so that the donor film is in proximity to a target area on an acceptor substrate. An optical assembly directs one or more beams of laser radiation to pass through the first surface of the donor substrate and impinge on the donor film so as to induce ejection of material from the donor film onto the acceptor substrate. Means are provided to mitigate or compensate for the variation in reflection of the laser radiation across an area of the donor substrate, so as to equalize a flux of the laser radiation that is absorbed in the donor film across the area of the donor substrate.
