A method includes providing a reservoir of randomly oriented fibers in a solution, dispensing the solution of randomly oriented fibers through a nozzle having an orientation component onto a porous substrate as a solution of aligned fibers, and immobilizing the fibers to form a fiber pre-form. A system includes a porous substrate, a deposition nozzle, a reservoir of randomly oriented fibers in solution connected to the deposition nozzle, the deposition nozzle position adjacent the porous substrate and connected to the reservoir, the nozzle to receive the randomly oriented fibers and output aligned fibers, and a vacuum connected to the porous substrate to remove fluid from the porous substrate as the deposition nozzle deposits the aligned fibers on the porous substrate to produce a fiber pre-form having aligned fibers.

Creating aligned and oriented fiber reinforced polymer composites

A method of manufacturing a superconducting tape includes forming a slurry of superconducting material, forming a slurry of sacrificial material, extruding the slurries of superconducting and sacrificial materials as interdigitated stripes onto a substrate, and removing the sacrificial material to form superconducting filaments.

Co-extrusion printing of filaments for superconducting wire

A structure has a substrate, a first material on the substrate, the first material having a binder and a first active material, periodically located trapezoidal voids that only partially extend from a top of the first active material towards the substrate, and an electrolyte material filling the trapezoidal voids.

Structures for interdigitated finger co-extrusion

A microchannel heat pipe formed on a substrate surface using co-extruding a primary material and a secondary material such that the primary material forms side wall portions that are spaced apart by the secondary material, and an upper wall portion is formed across the upper ends of the side walls to form a composite structure. After the primary material hardens, the secondary material is removed, whereby the hardened primary material forms a pipe body having an elongated central channel defined between opposing end openings. A working fluid is then inserted into the elongated central channel, and sealing structures are then formed over both end openings to encapsulate the working fluid.

Co-extruded microchannel heat pipes

A battery has a lithium anode, a separator adjacent the anode, and a cathode adjacent the separator opposite the anode, the cathode comprising interdigitated stripes of a first and second material, wherein the first material contains sulfur and the second material comprises a solid electrolyte.

A method for generating a microchannel heat pipe on a substrate surface includes co-extruding a primary material and a secondary material such that the primary material forms side walls that are spaced apart by the secondary material to form a composite structure. After the primary material hardens, the secondary material is removed, whereby the hardened primary material forms a pipe body structure having an elongated central channel defined between opposing end openings. A working fluid is then inserted into the elongated central channel, and sealing structures are then formed over both end openings to encapsulate the working fluid. The co-extrusion process is modified such that the side and upper walls are self-formed either while flowing inside a co-extrusion printhead, or immediately upon exiting the printhead.

A deposition nozzle has a housing, an inlet into the housing arranged to receive a solution carrying randomly oriented fibers, an orientation component within the housing, the orientation component positioned to receive the solution from the inlet and operate to produce aligned fibers in a predetermined, single direction, and an outlet on the housing arranged to receive the aligned fibers and deposit them on a substrate. A system includes a porous substrate, a deposition nozzle, a reservoir of randomly oriented fibers in solution connected to the deposition nozzle, the deposition nozzle position adjacent the porous substrate and connected to the reservoir, the nozzle to receive the randomly oriented fibers and output aligned fibers, and a vacuum connected to the porous substrate to remove fluid from the porous substrate as the deposition nozzle deposits the aligned fibers on the porous substrate to produce a fiber pre-form having aligned fibers.

A method of forming a flexible thermal regulation device having multiple functional layers. The layers of the device are formed using various manufacturing techniques and are then integrated to form a sheet having multiple devices disposed thereon. The individual devices are then formed from the sheet.

Method for roll-to-roll production of flexible, stretchy objects with integrated thermoelectric modules, electronics and heat dissipation

A method for generating a microchannel heat pipe on a substrate surface includes co-extruding a primary material and a secondary material such that the primary material forms side walls that are spaced apart by the secondary material to form a composite structure. After the primary material hardens, the secondary material is removed, whereby the hardened primary material forms a pipe body structure having an elongated central channel defined between opposing end openings. A working fluid is then inserted into the elongated central channel, and sealing structures are then formed over both end openings to encapsulate the working fluid.

Solar cells include bus bars and high aspect-ratio gridlines that are printed on a substrate, and localized melting is induced to slump or flatten the gridline 'vertex' portions that are disposed on the bus bars, while maintaining the high aspect-ratio of gridlines portions disposed on the substrate between the bus bars. The localized melting process is induced using one of several disclosed methods, such as rheological melting in which the two printed inks produce a compound that is relatively liquid. Localized melting is also induced using a deliquescing material (e.g., a flux or a solvent film) that is applied to the bus bar or gridline material. Also, eutectic melting is induced using a processing temperature that is between a melting point of the combined gridline/bus bar inks and the individual melting points of the inks alone. Laser-based melting and the use of copolymers is also disclosed.
