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: 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: 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 for coating of a thin film with a viscous material, such as a liquid, a paste, or an adhesive, at a desired thickness. In such a system (100), two films (112,114) move adjacent to one another, optionally in opposite directions, atop two rollers (102, 104) separated by a known gap (20) that defines a coating thickness, with the material being transferred from one film to the other. The rollers may be maintained in their relative positions by springs (116, 118) and/ or linear actuators (124a, 124b) and positioned using linear encoders (120). In alternate arrangements, the material to be coated could be low viscosity material such as a polymeric solution. Air knives (602a, 602b) may be provided near the gap to create an air flow that aids in preventing the free flow of low viscosity materials outside the bounds of the film during coating.

Abstract: A conductive coil fabricated by an additive manufacturing process. The coil is printed as a plurality of partially complete rounds, each printed as at least a portion of a respective layer of material. Pillars interconnecting successive ones of the partially complete rounds in different ones of the respective layers of material are also printed and may be staggered across a circumference of the partially complete rounds. Scaffolding elements such as a supporting material matrix and/or a core internal to the partially complete rounds of the coil may be printed as part of each respective layer of material concurrently with printing the plurality of partially complete rounds.

Abstract: Manufacture of 3D object by a printing method that enables the use 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: Systems and methods that prevent oxygen inhibition of a light-initiated polymerization reaction by purging the oxygen from reaction surfaces using inert gas flow. In some embodiments, oxygen is purged using a gas diffusion system that introduces, via a diffuser, an inert gas into a workspace between a UV light source and a UV curable layer of a workpiece. The diffuser may be made of a transparent or diffuse material to allow UV light to pass through it, and includes an array of micro-holes for the gas to pass through towards the workpiece. The inert gas flow may be heated to maintain a desired and uniform reaction temperature.

Abstract: Systems and methods that prevent oxygen inhibition of a light-initiated polymerization reaction by forcing the oxygen away from the reaction surfaces. In some embodiments, oxygen is purged by bringing a planarizing surface (e.g., a thin transparent film and/or a transparent planar surface) into contact with a layer of UV curable material disposed on a workpiece and then moving the planarizing surface away from the workpiece one the UV material is cured.
