Problems solved by technology

A possibly required change in the intensity of the laser beam can only be achieved here by defocusing or shifting the focus position of the laser beam; however, the beam profile of the laser beam is not changed thereby
[0004] However, in particular with regard to the greatest possible variability of the irradiation strategies achievable by means of corresponding devices, there is the possibility of targeted modification of the beam properties, in particular the beam profile, of the laser beam generated by the laser beam generating device needs

Embodiment Construction

[0032] figure 1 A schematic diagram of a device 1 according to an exemplary embodiment is shown. can be seen in figure 1 Only those partial parts of the device 1 that are relevant for explaining the principles described below are shown in .

[0033] The device 1 is used for the additive production of three-dimensional objects by successively selectively irradiating and subsequently curing layers of a building material 3 which can be cured by means of a laser beam 5 , that is to say, for example metal powder, layer by layer. 2. That is to say especially a technical component or a technical component group. The selective curing of the individual layers of build material to be cured is carried out on the basis of object-related build data. The corresponding construction data describe the geometrical or geometrical design of the object 2 to be additively produced in each case. The corresponding construction data can contain, for example, “sliced” CAD data of the object 2 to be...

Abstract

The invention relates to an apparatus (1) for additive manufacturing of three-dimensional objects (2) by successive, selective layer-by-layer exposure and thus solidification of construction materiallayers of a construction material (3) that can be solidified by means of a laser beam (5) generated by a laser beam generation device (4), comprising:a laser beam generation device (4) provided for generating a laser beam (5) with beam properties defined by at least one laser beam parameter, especially a beam profile defined by at least one laser beam parameter;a modulation device (9) assigned tothe laser beam generation device (4) provided for purposefully changing at least one laser beam parameter that influences the beam properties, especially the beam profile, of the laser beam (5) generated by the laser beam generation device (4) on the basis of a target value that is or can be specified, especially by a user.

Description

technical field [0001] The invention relates to a device for the additive manufacturing of three-dimensional objects by sequentially layer-by-layer selective irradiation and subsequent curing of build-up material layers consisting of a build-up material which can be produced by means of a laser beam generating device Laser beam curing. Background technique [0002] Corresponding devices for the additive production of three-dimensional objects are known per se. A typical embodiment of a corresponding device is a device for carrying out a selective laser sintering method or a selective laser melting method. An essential functional component of a corresponding device is the laser beam generating device, which is provided for generating a laser beam for selectively irradiating the individual build-up material layers. The laser beam has a beam characteristic defined by one or more laser beam parameters or a beam profile defined by one or more laser beam parameters. [0003] Th...
