Embodiment Construction

[0034] Refer below figure 1 One embodiment according to the present invention will be described. exist figure 1 The plant shown in is a laser sintering plant or a laser melting plant 1 . The laser sintering or laser melting system 1 has a processing or building chamber 3 with a chamber wall 4 for forming the object 2 .

[0035] A container 5 which is open at the top and has a container wall 6 is arranged in the treatment chamber 3 . A working plane 7 is delimited by the upper opening of the container 5 , and the region of the working plane 7 inside said opening that can be used for building the object 2 is referred to as the building area 8 .

[0036] Arranged in the container 5 is a support 10 movable in the vertical direction V, on which a base 11 is mounted, which closes the container 5 downwards and thus forms the bottom of the container. The base plate 11 can be a plate formed separately from the support 10 , which is fastened to the support 10 , or it can be formed i...

Abstract

An exposure control device (31) serves for equipping and / or retrofitting a generative layer-wise building device (1). The latter comprises an exposure device (20) which emits electromagnetic radiation(22) or particle radiation and is configured to irradiate positions to be solidified in a layer in such a way that after cooling they exist as an object cross-section or part of the same. The exposure control device (31) has a first data output interface (36), at which control commands can be output to the exposure device (20). The control commands which are output specify one of a plurality of exposure types wherein an exposure type is defined by a predetermined combination of a radiation energy density to be emitted by the exposure device (20) and a scanning pattern with which the radiation(22) is being directed to a region of a layer of the building material (15). Furthermore, the exposure control device (31) has a second data output interface (37) at which an exposure type can be output in real time in relation to a timing of the output of a control command specifying this exposure type.

Description

technical field [0001] The invention relates to an irradiation control device and an irradiation control method for use in the manufacture of at least one three-dimensional object by layer-by-layer application and selective curing of building materials and to a device and method for the layer-by-layer manufacture of at least one three-dimensional object. Background technique [0002] Devices and methods of this type are used, for example, in rapid prototyping, rapid prototyping and additive manufacturing. An example of this method is known under the designation "selective laser sintering or laser melting". Here thin layers of powdered build-up material are applied repeatedly and the build-up material in each layer is selectively cured by selectively irradiating with laser beams the locations corresponding to the cross-section of the object to be produced. Here, the powder particles at these locations are partially or completely melted by the energy introduced by the radiati...
