A method for displacing a continuous energy beam includes radiating the continuous energy beam onto a powder material and displacing the energy beam by overlaying an optical deflection of the energy beam using a deflection device and a mechanical deflection of the energy beam using a scanner device. The mechanical deflection is configured to position the energy beam at a plurality of irradiation positions and the optical deflection is configured to deflect the energy beam around each of the irradiation positions within a beam region onto at least one beam position of the sequence of beam positions. The optical deflection and the mechanical deflection are changed simultaneously or successively in order to scan the sequence of beam positions using the energy beam.

In an example of a method for three-dimensional (3D) printing, one or more dispersions is/are sprayed to form a layer including build material particles and a liquid agent. The liquid agent is evaporated from the layer to form a build material layer, and based on a 3D object model, a binder agent is applied on at least a portion of the build material layer.

A three-dimensional printing system for fabricating a three-dimensional article includes a motorized build platform, a dispensing module, a pulsed light source, an imaging module, a movement mechanism, and a controller. The imaging module receives radiation from the pulsed light source and includes a two-dimensional mirror array. The movement mechanism imparts lateral motion between the imaging module and the build platform. The controller is configured to operate the motorized build platform and the dispensing module to form a layer of build material at a build plane, operate the movement mechanism to laterally scan the imaging module over the build plane, operate the pulsed light source to generate a sequence of radiation pulses that illuminate the mirror array, and operate the mirror array to selectively image the build material.

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.
