Embodiment Construction

[0017] A method and a system for reusing surplus powder from a device for the generative manufacture of three-dimensional objects are described below by means of figures.

[0018] figure 1 A schematic diagram of a production 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.

[0019] The laser sintering system has an upwardly open frame 1 which includes a vertically movable plate 2 situated therein, which supports a three-dimensional object 3 to be produced. Frame 1 and plate 2 internally define a fabrication space. The plate 2 is connected to a lifting mechanism 12 which moves the plate in the vertical direction so that the respective layers of the objects 3 to be consolidated lie in a working plane 4 .

[0020] Although this is figure 1 Not shown, a metallic base plate can be manually placed on the plate and fixed or screwed if necessary. Such a substrate is hea...

Abstract

The invention relates to a method and a system for reusing residual powder from an installation for the rapid prototyping of three-dimensional objects (3), including the steps of sieving the residual powder (3a) or for mixing the residual powder (3a) with fresh powder. The method is characterized by adding the step of modifying a property of the resulting powder.

Description

technical field [0001] The present invention relates to a method and a system for reusing surplus powder from an apparatus for the generative manufacture of three-dimensional objects. Background technique [0002] DE 201 07 262 U1 describes a method and a system for recycling powders for the manufacture of three-dimensional objects. The system includes a manufacturing device that applies powder material layer by layer to a support or a previously applied layer and consolidates the powder material at locations corresponding to the article by means of energetic radiation superior. The unconsolidated residual powder is fed directly from the production plant via a conveying line to a screening device arranged separately from the production plant, which screens the residual powder supplied from the production plant. The sieved residual powder is conveyed via another conveying line into a storage container and can be reused. [0003] DE 103 42 883 A1 describes a production plan...
