Printing of three-dimensional metal structures with a sacrificial support

A method for 3d printing includes printing a first metallic material on a substrate as a support structure (48). A second metallic material, which is less anodic than the first metallic material, is printed on the substrate as a target structure (46), in contact with the support structure. ... Orbotech Ltd

Acousto-optic deflector with multiple output beams

Optical apparatus includes an acousto-optic medium and an array of multiple piezoelectric transducers attached to the acousto-optic medium. A drive circuit is coupled to apply to the piezoelectric transducers respective drive signals including at least first and second frequency components at different, respective first and second frequencies and with different, respective phase offsets for the first and second frequency components at each of the multiple piezoelectric transducers.. ...

Angled lift jetting

An apparatus for material deposition on an acceptor surface includes a transparent donor substrate having opposing first and second surfaces, such that at least a part of the second surface is not parallel to the acceptor surface, and including 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 part of the second surface that is not parallel to the acceptor surface, so as to induce ejection of droplets of molten material from the donor film onto the acceptor surface.. ...

Lift printing of conductive traces onto a semiconductor substrate

A method for metallization includes providing a transparent donor substrate (34) having deposited thereon a donor film (36) including a metal with a thickness less than 2 μm. The donor substrate is positioned in proximity to an acceptor substrate (22) including a semiconductor material with the donor film facing toward the acceptor substrate and with a gap of at least 0.1 mm between the donor film and the acceptor substrate. ...

Lift printing system

Printing apparatus (20) includes a donor supply assembly (30), which provides a transparent donor substrate (26) having opposing first and second surfaces and a donor film formed on the second surface so as to position the donor film in proximity a target area (28) on an acceptor substrate (22). An optical assembly (24) directs multiple output beams of laser radiation simultaneously in a predefmed spatial pattern 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 according, thereby writing the predefined pattern onto the target area of the acceptor substrate.. ...

Printing of 3d structures by laser-induced forward transfer

A method for material deposition includes providing a transparent donor substrate (34) having opposing first and second surfaces and a donor film (36) including a metal formed over the second surface. The donor substrate is positioned in proximity to an acceptor substrate (22), with the second surface facing toward the acceptor substrate, in an atmosphere containing oxygen. ... Orbotech Ltd

Pulsed-mode direct-write laser metallization

A method for manufacturing includes coating a substrate (22) with a matrix (28) containing a material to be patterned on the substrate. A pattern is fixed in the matrix by directing a pulsed energy beam to impinge on a locus of the pattern so as to cause adhesion of the material to the substrate along the pattern without fully sintering the material in the pattern. ...
