SYSTEMS AND METHODS FOR NEGATIVE 3D PRINTING MACHINE AT HIGH RESOLUTION
Methods and apparatus for the fabrication of solid three-dimensional objects from liquid polymerizable materials at high resolution. A material (202) is coated on a film (204) non digitally, excess material is removed digitally, by laser, leaving a negative image of a layer to be printed, and the image is then engaged with existing portions of an object (220) being fabricated and exposed to a non-digital UV curing light source. Since the only part of digitizing 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.

Laser-based droplet array jetting of high viscous materials
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.

Systems and methods for dispensing liquid materials as may be used in applications for coating flexible films and the like. Such a film may be coated by dispensing a rheological material onto its surface while drawing the film through a gap between a pair of rollers. The gap defines the thickness of a layer of the material applied to the film and is maintained at a desired width by microwires positioned through the gap. Another film across the gap from that to which the rheological material is applied aids in the coating of the layer and a contact area of the second film may be adjusted relative to the gap, e.g., when changing materials or when the coating film becomes abraded or deformed.

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.

LASER-BASED DROPLET ARRAY JETTING OF HIGH VISCOUS MATERIALS
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.
