Abstract: A three-dimensional dental device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the dental device will be formed. Active dental material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional dental device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

Abstract: A method of solid free form fabrication (SFF) is disclosed. The method comprises: 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 also comprises, for each of at least a few of the layers, dispensing a building material on a receiving medium, straightening the building material, and selectively ablating the building material according to respective slice data.

Abstract: Systems and methods in which a material or materials (e.g., a viscous material) are printed or otherwise transferred onto an intermediate substrate at a printing unit(s). The intermediate substrate having an image of material printed thereon is subsequently transferred to a sample building unit, and the image of material is transferred from the intermediate substrate to a sample at the sample building unit. Optionally, the printing unit(s) includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred from the donor substrate onto the intermediate substrate at the printing unit(s). Each of the printing units may employ a variety of printing or other transfer technologies. The system may also include material curing, heating, sintering, ablating, material filling, imaging and cleaning units to aid in the overall process.

Abstract: 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.

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: In a first approach, a vacuum cell comprises a porous plate and a vacuum force generated by gas being drawn thorough the porous plate is used to pick electronic components from a donor substrate. After transport of the vacuum cell to a placing area, dots of liquid material may be deposited on a top surface of the porous plate adjacent to one or more picked components in order to disrupt the vacuum force and release the picked components onto a receiving substrate. In a refinement of the first approach, the porous plate contains a plurality of picking holes for selectively picking components. Certain picking holes can be fluidly coupled to the vacuum, allowing components to be attached within those picking holes, while other picking holes can be closed or rendered inactive with dots of liquid material deposited on a top surface of the porous plate.

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 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 intermediate substrate at a first printing unit, the intermediate substrate having the dot-like portions of material printed thereon is transferred to a second printing unit, and the dot-like portions of material are transferred from the intermediate substrate to a final substrate at the second printing unit. Optionally, the first printing unit 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 intermediate substrate at the first printing unit. Each of the first and second printing units may employ a variety of printing or other transfer technologies.
