Embodiment Construction

[0020] figure 1 A device for mixing powder 17 is indicated. The device has a container 2 which has a bottom and is provided with a fluid-permeable plate 3 in the area of ​​its bottom. Furthermore, the device 1 is equipped with a stirring device 4 . In the region of its base, the container 2 is provided with an inflow opening 15 through which a fluid 16 can flow into the container 2 . The container 2 has a cover at the upper end, which is provided with a powder inlet opening 14 and a fluid outlet opening 12, on which a filter element 13 is mounted. The bottom of the container 2 is here centrally provided with an outlet opening 11 which can be closed. The container has a horizontal cross-section suitable for good mixing of the powder. The horizontal cross-section is circular in this embodiment, but may also be polygonal, elliptical, etc. in other embodiments. Alternatively, the container 2 has a fluid permeable bottom which is somewhat funnel-shaped.

Abstract

The invention relates to a device for mixing powder (17) for a device for producing a three-dimensional object, comprising: a stirring device (4) and a pressure-fluid supply means for fluidizing powder (17). A device (100) for producing the three-dimensional object (503) is adjusted to connect with the device for mixing powder (17) and form a system with the device for mixing powder.

Description

technical field [0001] The invention relates to a device for mixing powders for a device for producing three-dimensional objects, in particular a laser sintering device, which performs the mixing with low energy consumption and produces resource-efficiently. Furthermore, the invention relates to a device for producing three-dimensional objects. Background technique [0002] Powder-based generative methods for producing three-dimensional objects are generally known, such as selective laser sintering, in which the three-dimensional objects are formed layer by layer by solidification of powder-like materials. In selective laser sintering, solidification takes place by means of a laser beam incident on the powder layer. Uncured powder is usually mixed with new powder and reused. In particular during selective laser sintering, when the old powder is returned to the material circuit, material from the various sintering processes can result in stratification in the old powder con...
