    Abstract: Methods and apparatus for the fabrication of solid three-dimensional objects from liquid polymerizable materials at high resolution. A material is coated on a film non-digitally, excess material is removed digitally, by laser, leaving an image of a layer to be printed, and the image is then engaged with existing portions of an object being fabricated and exposed to a non-digital UV curing light source. Since the only part of the process that is digital is the material removal, and this part is done by laser, the speed of printing and the robustness of the manufacturing process is improved significantly over conventional additive or 3D fabrication techniques.

    Abstract: Laser jetting of droplets of a viscous material, such as an ink, is performed by coating a layer of ink on a mesh-like transport screen, with the ink being retained within spaces of the mesh-like transport screen. The ink-coated mesh-like transport screen is conveyed to a working area and a laser beam is used to heat the ink within the spaces of the mesh-like transport screen, thereby causing ink droplets to be jetted from the spaces of the mesh-like transport screen. Structures are formed on a receiving substrate arranged near the working area by jetting the ink droplets, either in an aggregation or sequentially, across a gap from the mesh-like transport screen to the receiving substrate and displacing the mesh-like transport screen and the laser beam relative to one another at times between the jetting of the droplets, or by directly printing ink droplets onto the receiving substrate.

    Abstract: Systems and methods in which dot-like portions of a material (e.g., a viscous material such as a solder paste) are printed or otherwise transferred onto an electronic component at a first printing unit, and the electronic component is subsequently placed onto a substrate with the portions of viscous material between the electronic component and the substrate. Optionally, a printing unit which prints the dots of material onto the electronic component includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred in the individual dot-like portions from the donor substrate onto the electronic component by the printing unit. The system may also include imaging units to aid in the overall process.

    Abstract: Systems for material deposition. One such system includes a number of containers arranged relative to one another in a conical or other shape, pointing toward a common deposition point. When not actively depositing material, the containers are held at a distance from the deposition point. Another system has a rod disposed within a container and a flexible tip on the rod seals a material exit of the container when biased closed. Pressurized gas introduced into the container forces the rod away from the material exit and material from the container. In yet another system, a container includes a barrel adapter having a one-way air valve that seals the container and creates a vacuum, preventing material from leaking from the container. Upon application of a pressurized gas, the one-way valve is forced open and material is deposited from the container. The valve closes automatically in the absence of the gas.

    Abstract: The laser-induced dispensing system incudes a cartridge assembly having a supply reel for supplying a foil having a light transmissive layer wound around the supply reel, and a take-up reel for taking up the foil. There is provided a coating device for coating the foil by a donor material during a motion of the foil. The laser-induced dispensing system also includes a irradiation head having optics configured for focusing a laser beam. Additionally, a controller, for controlling the cartridge assembly to establish motion of the foil, and the optics to focus the laser beam onto the foil at a location downstream the outlet of the coating device so as to release droplets of the donor material from the foil is provided.

    Abstract: A laser-induced dispensing system for material processing is disclosed. The laser-induced dispensing system includes a fiber bundle having optical fibers. The optical fibers have first ends arranged at the first interface and second ends arranged at the second interface. Additionally, optics that direct laser beams transmitted from the second interface by the optical fibers toward a material to be deposited a substrate is provided. The optics is configured to focus the laser beams on the material to be deposited, thereby causing the material to be deposited to be released onto the substrate. Each of the optical fibers having a first end that is adjacent to a first end of another of the optical fibers at the first interface have a second end that is non-adjacent to a second end of the another of the optical fibers at the second interface.
