    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: 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: 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: A method of solid free-form fabrication (SFF) includes receiving SFF data collectively pertaining to a three-dimensional shape of the object and comprising a plurality of slice data each defining a layer of the object. The method further includes dispensing a building material containing a solvent, drying the building material so as to remove at least some of the solvent from the building material and leveling the building material. The method further includes selectively ablating the building material, for at least several of the multiple layers, according to the slice data corresponding to the layer, and dispensing at least one additional building material onto the building material to fill vacant regions formed in the multiple layers by the selective ablation. A resolution of the dispensing of the additional building material may be less than a resolution of the selective ablation.

    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: A leveling system for a 3D printing system for laser dispensing includes inner and outer frames, each supported at its corners by respective actuators of first and second sets of actuators. The outer frame supports an optical plane within which material to be dispensed by laser irradiation is disposed. The inner frame supports a receiving medium plane within which a substrate on which said material to be dispensed by laser irradiation is disposed. Each actuator operates independently to displace a respective frame corner in the vertical direction. The inner and outer frames each is attached at their respective corners to a respective actuator by a rod, thus allowing the inner and outer frames to freely rotate with respect to one another. An additional frame may support sensors for monitoring the 3D printing system.
