Problems solved by technology

However, the parameters of the energy beam determined during additive manufacturing may still deviate from the parameters of the energy beam, since the surface of the determined substrate may deviate from the surface of the build material arranged in the build plane

Embodiment Construction

[0034] figure 1 A device 1 is shown for the additive manufacturing of three-dimensional objects by sequential layer-by-layer selective irradiation and consolidation of layers of building material which can be consolidated by means of an energy beam 2 . exist figure 1 In the case shown, device 1 carries out a determination process in which parameters of energy beam 2 can be determined. In other words, during the determination, no building material is arranged on the carrier unit 3 , which is height-adjustably movable in the building chamber 4 , as indicated by arrow 5 , or delimits the bottom side of the building chamber 4 .

[0035] exist figure 1 In the case shown, determination means 6 are provided, which can be arranged in the beam guiding plane 7, for example in the same plane in which the building material can be arranged in the normal mode of operation of the device 1, in order to Irradiated via energy beam 2 . In order to guide the energy beam 2 through the beam-gui...

Abstract

Apparatus (1) for additively manufacturing three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated bymeans of an energy beam (2, 2'), which apparatus (1) comprises a determination device (6) adapted to determine at least one parameter of the energy beam (2, 2'), wherein the determination device (6)comprises at least one determination base body (11) arrangeable or arranged in a beam guiding plane (7), in particular a build plane, wherein at least one surface parameter of a surface (15) of the determination base body (11) is defined dependent on a surface parameter of a specific build material arrangeable or arranged in a build plane in an additive manufacturing process performed on the apparatus (1).

Description

technical field [0001] The invention relates to a device for the additive manufacturing of three-dimensional objects by selectively irradiating and solidifying layers of building material in successive layers, which can be consolidated by means of energy beams, the device comprising determining means adapted to For determining at least one parameter of the energy beam, wherein the determining device comprises at least one determining substrate which can be arranged or arranged in a beam guiding plane, in particular in a build plane. Background technique [0002] Devices for the additive manufacturing of three-dimensional objects are generally known from the prior art. Typically, the determining means are used to determine one or more parameters of the energy beam, such as eg the focus position of the energy beam in the build plane, the intensity of the energy beam and the shape of the spot of the energy beam. Determination of the energy beam parameters is crucial for object...
