    摘要： 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). Analogously, at least one energy beam rotational axis (46) is proposed for rotating at least some of the energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61) in an additive manufacturing device in which the starting material (4) is held on a base surface (3, 15, 30, 36, 52) by a centrifugal acceleration.

    摘要： The present invention relates to a device as well as a method for creating three-dimensional structures consisting of a material to be consolidated, in particular a material containing organopolysiloxane, by way of locally selective consolidation of the latter as a result of light-induced organic cross-linking. The device is characterized by a movable focusing optical system for the formation of one or a plurality of laser foci, wherein either the laser beam of a laser source can be introduced into the material to be consolidated through the material container and a movable carrier unit is arranged in said container or the focusing optical system is immersed into the material bath and the laser beams can be introduced into the material to be consolidated via a beam exit area of the focusing optical system. In the method, a focusing optical system that is movable in at least one plane is used for the formation of at least one laser focus, and a movable carrier unit is positioned in the material to be consolidated in one embodiment.
