Publication number: 20190232430Abstract: The invention belongs to the field of additive manufacturing of amorphous alloy, and discloses a laser 3D printing forming system of amorphous alloy foil and a forming method thereof. The unnecessary material of the amorphous alloy foil is cut by a first laser and then the remaining portion is selectively scanned and heated by a second laser so that the amorphous alloy is heated to be in a superplastic state in the supercooled liquid region. Then, the amorphous alloy foil is rolled by a preheated roller in combination with the ultrasonic vibration to achieve interatomic bonding between layers of the amorphous alloy foil, and the amorphous alloy foil is then rapidly cooled, so that an amorphous alloy part with a large size, a complicated shape and a porous structure is formed.Type: ApplicationFiled: March 23, 2018Publication date: August 1, 2019Inventors: Pan GONG, Fangwei LI, Xinyun WANG, Jianhua MO, Lei DENG, Junsong JIN

Publication number: 20190232435Abstract: The liquid-assisted micromachining methods include methods of processing a substrate made of a transparent dielectric material. A working surface of the substrate is placed in contact with a liquid-assist medium that comprises fluorine. A focused pulsed laser beam is directed through a first substrate surface and through the opposite working surface to form a focus spot in the liquid-assist medium. The focus spot is then moved over a motion path from its initial position in the liquid-assist medium through the substrate body in the general direction from the working surface to the first surface to create a modification of the transparent dielectric material that defines in the body a core portion. The core portion is removed to form the substrate feature, which can be a through or closed fiber hole that supports one or more optical fibers. Optical components formed using the processed substrate are also disclosed.Type: ApplicationFiled: January 25, 2019Publication date: August 1, 2019Inventors: Jeffery Alan DeMeritt, Davide Domenico Fortusini, Andrey Kobyakov, David Mark Lance, Leonard Thomas Masters, Ulrich Wilhelm Heinz Neukirch, Alexander Mikhailovich Streltsov, James Scott Sutherland
