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.

Lift printing using thin donor foils

A method for manufacturing includes applying patterned electromagnetic energy to each of a sequence of layers of a dry film comprising a photosensitive material so as to create in the photosensitive material in each of the layers a respective two-dimensional (2D) pattern corresponding to a slice of a predefined three-dimensional (3D) structure. The layers in the sequence in which the respective 2D pattern has been created are laminated together to produce a multi-layer stack. The multi-layer stack is developed so as to remove the photosensitive material in which the 2D pattern has not been created, thereby forming the 3D structure.

Hybrid, multi-material 3D printing

A method for manufacturing includes coating a substrate () with a matrix () containing a material to be patterned on the substrate. A pattern () is fixed in the matrix by directing an energy beam to impinge on the coated substrate so as to fix the pattern in the matrix without fully sintering the pattern. The matrix remaining on the substrate outside the fixed pattern is removed, and after removing the matrix, the material in the pattern is sintered.
