The disclosure provides methods of additive manufacture of components in layers in a powder bed by at least two laser beams that can be deflected two-dimensionally over the same powder bed region. Each laser focal spot is projected onto the power bed and is or is set to a diameter of less than or equal to 300 μm. Components to be produced in the powder bed region are manufactured by each of the laser beams, and each individual surface contour of the component is manufactured solely by one of the laser beams.

Methods for the additive manufacture of components in layers, and corresponding computer program products

Methods and computer-readable media for producing at least one portion of a layer of a three-dimensional component by irradiating at least one powder layer by at least one high-energy beam, e.g., a laser beam are disclosed. The methods include irradiating the powder layer by the at least one high-energy beam in a processing field, wherein the at least one high-energy beam is moved in a continuous oscillating movement over the powder layer in a first direction to produce a line-shaped irradiation region in which the powder layer is melted, and wherein the line-shaped irradiation region is moved over the powder layer in a second direction that differs from the first to produce the portion of the layer of the three-dimensional component.

Irradiation devices, machines, and methods for producing three-dimensional components

The invention relates to a method for the manufacture of a molding through generative processing methods, in particular through selective laser melting, wherein a model of a molding is built from a powder material according to CAD data, wherein an application unit is used to apply a powder layer and the powder layer applied is fixed to a layer arranged there under or a base plate by means of radiation, characterized in that prior to applying a first layer onto a build platform or a base plate, a sensor assembly having a sensor level which is located in relation to the levelling level of a levelling assembly for the applied powder layer is allocated to the build platform or the base plate, the build platform or the base plate is moved in relation to the sensor assembly until the sensor assembly emits a signal for stopping the build platform to a drive in an intermediate position, and starting from the intermediate position, the build platform or the base plate is moved by a distance to adjust the layer thickness of the first powder layer and is positioned in a starting position.
