A method of additive manufacture is disclosed. The method may include restricting, by an enclosure, an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure. The method may further include running multiple machines within the enclosure. Each of the machines may execute its own process of additive manufacture. While the machines are running, a gas management system may maintain gaseous oxygen within the enclosure at or below a limiting oxygen concentration for the interior.

A laser processing device includes a conveyance device, a laser irradiating unit, a controller, and a guide. The conveyance device conveys a strip electrode in a conveyance direction. The laser irradiating unit irradiates the strip electrode with a laser beam. The laser irradiating unit is configured to change the irradiating direction of the laser beam. The controller controls the laser irradiating unit so as to cut the strip electrode into a tab shape by causing the laser beam to move along a predetermined path on the strip electrode. The guide holds the strip electrode. The guide includes a notch. The notch has a shape that follows at least a portion of the predetermined path.

A process for delineating a population of electrode structures in a web includes laser ablating the web to form ablations in the web, each ablation being formed by removing a portion of an electrochemically active layer to thereby expose a portion of an electrically conductive layer. The process includes forming alignment features in the web that are formed at predetermined locations on the web. The process also includes laser machining the web to form weakened tear patterns in the web that delineate members of the electrode structure population, each of the delineated members being individually bounded, at least in part, by a member of the weakened tear patterns that is adapted to facilitate separation of delineated members, individually, from the web by an application of a force, the alignment features being used to aid in the formation of the weakened tear patterns.

Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

A reel-to-reel lamination method to laminate a metal foil or circuitry pattern on the fly. The method includes applying a UV laminate or thermoset laminate to the metal foil or the circuitry pattern reel to reel, and then apply a UV radiation or heat to the laminate. There can be an optional enclosure connected to a suction source. The enclosure can have a flexible bladder that physically compresses the laminate.

A method and an apparatus of a powder bed fusion additive manufacturing system that enables a quick change in the optical beam delivery size and intensity across locations of a print surface for different powdered materials while ensuring high availability of the system. A dynamic optical assembly containing a set of lens assemblies of different magnification ratios and a mechanical assembly may change the magnification ratios as needed. The dynamic optical assembly may include a transitional and rotational position control of the optics to minimize variations of the optical beam sizes across the print surface.

Provided is a method of manufacturing a glass film, including: a conveying step of conveying an elongated glass film (G) along a longitudinal direction thereof; and a cutting step of irradiating the glass film (G) with a laser beam (L) from a laser irradiation apparatus (19) while conveying the glass film (G) through the conveying step, to thereby separate the glass film (G). The cutting step includes generating a thread-like peeled material (Ge) in a helical shape from an end portion of the separated glass film (G) in a width direction. The thread-like peeled material (Ge) has a width (W) of 180 μm or more and 300 μm or less. In addition, the thread-like peeled material (Ge) has a helical diameter (D) of 80 mm or more and 200 mm or less.
