A fill tool system that fills, seals, and inspects a heat pipe array, which includes one or more heat pipes with heat pipe working fluid.

A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.

A system for laser processing includes a plate assembly having a first plate, a second plate secured to the first plate, and a pressure chamber located between the plates, a connector extending into and in fluid communication with the pressure chamber, and a fixture having a first end attached to the second plate of the plate assembly, a second end having surface having at least one opening and shaped to fit a part to be retained and laser processed, and a conduit extending therethrough in fluid communication with the pressure chamber and the at least one opening. During use, a pressure generated by a pump may be communicated to the conduit of the fixture through the pressure chamber to provide pressure (e.g., a suction effect) at the opening(s) to secure the part in place, e.g., with respect to another part, so they can be laser processed.

A method and an apparatus for collecting powder samples in real-time in powder bed fusion additive manufacturing may involves an ingester system for in-process collection and characterizations of powder samples. The collection may be performed periodically and uses the results of characterizations for adjustments in the powder bed fusion process. The ingester system of the present disclosure is capable of packaging powder samples collected in real-time into storage containers serving a multitude purposes of audit, process adjustments or actions.

A laser apparatus includes: a first vacuum chamber, wherein machining is performed on a target substrate in the first vacuum chamber; a laser facing the first vacuum chamber; a carrier disposed in the first vacuum chamber, wherein the target substrate is seated on the carrier; a chamber window disposed in one surface of the first vacuum chamber, wherein a laser beam emitted by the laser passes through the chamber window; a first protection window positioned between the carrier and the chamber window; a second vacuum chamber disposed at a first side of the first vacuum chamber; and a transfer unit configured to transfer the first protection window to the second vacuum chamber.

For allowing a crack to progress between respective lines reliably while shortening a laser beam irradiation time, a method for processing SiC material includes allowing a laser beam to be absorbed in a cutting scheduled plane of an SiC material to form an altered pattern including a plurality of line-shaped altered regions; and cutting the SiC material along the cutting scheduled plane, wherein a plurality of line-shaped main altered regions extending in a predetermined direction, arranged at a first pitch P1 and included in altered region groups is formed, and a plurality of altered region groups is arranged at a second pitch P2 larger than the first pitch P1.

The present invention introduces a scanning arrangement and a method suitable for coating processes applying laser ablation. The arrangement is suited to prolonged, industrial processes. The arrangement comprises a target, which has an annular form. The laser beam direction is controlled by a rotating mirror locating along the center axis of the annular target. The scanning line will rotate circularly along the inner target surface when the mirror rotates. The focal point of the laser beams may be arranged to locate on the inner target surface to ensure a constant spot size. A ring-formed, a cylinder-shaped or a cut conical-shaped target may be used. The inner surface of the target may thus be tapered in order to control the release direction of the ablated material towards a substrate to be coated.

A method of manufacturing a flexible device includes joining a first surface of a support substrate to a back surface of a flexible substrate, the first surface being opposite to a second surface of the support substrate; forming an element layer on a front surface of the flexible substrate; and performing multidirectional oblique irradiation of an interface and its vicinity between the support substrate and the flexible substrate with laser light from the second surface of the support substrate to detach the support substrate from the flexible substrate.
