Patent number: 11820047
Abstract: The invention relates to an additive manufacturing method in which a component (10, 42, 43, 44, 45) is produced in layers using an energy beam (8, 41, 58) which solidifies a starting material (4) and is irradiated by energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61) while the starting material (4) is held by a base surface (3, 15, 30, 36, 52) arranged on a base element (2, 16, 29, 35, 51). While the starting material (4) is being irradiated with the energy beam (8, 41, 58), the base element (2, 16, 29, 35, 51) is moved by a rotational component which has a base element rotational axis, wherein the starting material (4) is held on the base surface (3, 15, 30, 36, 52) by a centrifugal acceleration generated by the rotational component. The invention is characterized in that a rotational movement is produced for at least some of the energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61).

Abstract: In a method for aligning a polarization-maintaining optical fiber, in which the optical fiber (7a, 7b, 7c) is held in clamping fashion by means of a clamping device (12, 19, 23), a given rotational position of the optical fiber (7a, 7b, 7c) about the fiber longitudinal axis is detected, and the optical fiber (7a, 7b, 7c) is rotated about the fiber longitudinal axis by means of the clamping device (12, 19, 23), it is proposed that at least one clamping element (13, 14, 20-22, 24-27) of the clamping device (12, 19, 23), said clamping element abutting against the optical fiber (7a, 7b, 7c), is moved relative to at least one further clamping element (13, 14, 20-22, 24-27) of the clamping device (12, 13, 17), said at least one further clamping element likewise abutting against the optical fiber (7a, 7b, 7c), for the purposes of rotating the optical fiber (7a, 7b, 7c). Moreover, a correspondingly configured apparatus is presented.
