Abstract: A method for fabricating a three-dimensional (3D) electronic device. A liquid support material (e.g., an epoxy acrylate with a photoinitiator) is applied by a laser-induced forward transfer (LIFT) process to a printed circuit board (PCB) having one or more connectors and one or more electronic components thereon, and then cured to solid form by cooling and/or exposure to ultraviolet (UV) radiation. A layer of conductive material (e.g., a metal) is printed on the solidified support material by LIFT to electrically connect the one or more electronic components to respective ones of the connectors on the PCB. Subsequently, the layer of conductive material is dried by heating and metal particles in the conductive layer sintered using a laser beam. The assembly may then be encapsulated in an encapsulant.

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 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.
