Control of lift ejection angle

An apparatus for material deposition on an acceptor surface includes a transparent donor substrate having opposing first and second surfaces, and a donor film on the second surface. The apparatus additionally includes an optical assembly, which is configured to direct a beam of radiation to pass through the first surface of the donor substrate and impinge on the donor film at a location on the second surface so as to induce ejection of droplets of molten material from the donor film at an angle that is not normal to the second surface at the location onto the acceptor surface.. ...

Methods and apparatus for printing high-viscosity materials

A method for disposing material includes positioning a donor film including a donor material at a predefined distance from an acceptor substrate, the donor film facing toward the acceptor substrate. One or more pulses of laser radiation are directed to impinge on the donor film at a given location so as to induce formation of a protrusion made from the donor material. ... Orbotech Ltd
