Embodiment Construction

[0014] figure 1 A schematic diagram of a device according to the invention for producing a three-dimensional object 3 is shown, which is designed as a laser sintering device in the exemplary embodiment.

[0015] The laser sintering device has an upwardly open frame 1 and a vertically movable plate 2 within the frame, the plate carrying a three-dimensional object 3 to be manufactured. The frame 1 and the plate 2 internally define a manufacturing space. The plate 2 is connected to a lifting mechanism 12 which moves it in the vertical direction so that the layer to be consolidated of the current object 3 is in a working plane 4 . The frame 1 and the flat panel 2 are modularly connected to each other to form a replaceable rack. After the production of the three-dimensional object 3 has been completed, the exchangeable frame and the object 3 produced therein can be removed from the device and replaced by a new exchangeable frame.

[0016] Furthermore, an applicator 5 is provided...

Abstract

The present invention relates to a frame (1) of a device for manufacturing a three-dimensional object (3). The device manufactures the three-dimensional object (3) by solidifying a powder or liquid building material (3a) layer by layer at locations in each layer corresponding to the cross-section of the object (3) to be manufactured in a building space. The building space is defined by the frame (1) and a platform (2) inside the frame (1), wherein the frame (1) comprises at the inner side facing the building space glass ceramic plates.

Description

technical field [0001] The invention relates to a frame for a device for manufacturing three-dimensional objects. Background technique [0002] A frame of the same type for a device for manufacturing three-dimensional objects is disclosed in WO 00 / 21736A. The device produces a three-dimensional object by layer-by-layer consolidation of a powdery construction material by means of a laser or another energy source at positions corresponding to the cross-section of the object to be produced in the individual layers. The frame and plate define a fabrication space in which three-dimensional objects are fabricated. The frames and panels are modularly interconnected to form interchangeable racks, wherein the interchangeable racks can be loaded into and removed from the device. [0003] A similar device for producing three-dimensional objects is known from DE 199 39 616 A1. In devices according to this prior art, the production space is usually heated to a temperature of 100° C. t...
