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 heat 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 three-dimensional 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 device will be formed. Active material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

Abstract: Manufacture of a 3D object by a printing method that enables the use of several reactive materials sequentially. A laser-enhanced jetting-based 3D printer forms successive layers of reactive compositions on one another and the first and subsequent layers are allowed to crosslink between the printings to ultimately form the 3D object. Additional reactive compositions may be printed prior to the crosslinking. The crosslinking may be effected by heating, with or without a catalyst, and post printing curing may be employed after the 3D object is formed.

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: 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: Systems and methods for printing a printed circuit board (PCB) from substrate to full integration utilize a laser-assisted deposition (LAD) system to print a flowable material on top of a substrate by laser jetting to create a PCB structure to be used as an electronic device. One such system for PCB printing includes a jet printing unit, an imaging unit, curing units, and a drilling unit to print metals and other materials (epoxies, solder masks, etc.) directly on a PCB substrate such as a glass-reinforced epoxy laminate material (e.g., FR4) or others. The jet printing unit can also be used for sintering and/or ablation of materials. Printed materials are cured by heating or by infrared (IR) or ultraviolet (UV) radiation. PCBs produced according to the present systems and methods may be single-sided or double-sided.

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. The system may also include material curing and imaging units to aid in the overall process.

Abstract: A vacuum chuck system may include a vacuum chuck and a vacuum stopper collection and dispensing system. The vacuum chuck may include a ceramic plate with a retaining surface. The retaining surface may include a plurality of depressions and a plurality of openings, each of the openings being disposed on a bottom surface of one of the depressions and fluidly coupled to a vacuum pump. Vacuum stoppers may be used to seal one or more of the openings so as to restrict the vacuum area of the vacuum chuck. The vacuum stopper collection and dispensing system may be used to collect vacuum stoppers from and dispense vacuum stoppers onto the retaining surface. In addition or in the alternative, an electromagnet or a robotic arm may be used to move a vacuum stopper from a blocking position to a non-blocking position on the retaining surface.
