Embodiment Construction

[0057] figure 1 The accumulation of material layers 1 laid on top of one another is schematically shown by means of the proposed additive manufacturing method, corresponding to the formation of the structure 2 into said accumulation by the core-envelope system as described above. middle. The compression of the material layer 1 before the actual laser processing allows, on the one hand, to be able to work with better accuracy, and on the other hand, the surface properties can be improved, because the powder particles are fused more compactly with each other, which This results in a homogenization of the distribution of the melted material and better space filling.

[0058] figure 2 A second schematic representation of the created structure 2 , which forms a body, is shown schematically, wherein the outer regions of the walls 4 of the body 3 are calibrated. It is noted that both sides 5 are calibrated, while the other regions are not further compressed and thus retain their ...

Abstract

The invention relates to a method for producing a body by means of an additive manufacturing method (AM) using metal powder, the method having the following steps: - taking into account at least one part of the body to be processed In the case of an area, the body is designed computer-simulated and the data is transmitted to an additive manufacturing device, in particular an additive powder bed manufacturing device, to continuously provide metal powder for building the powders arranged on top of each other layer, - continuously hardening parts of the powder layer into at least one predetermined structure in the powder layers arranged one above the other, wherein the structure is at least partially filled with the metal powder of the powder layer, And, the volume created by means of the structure is aligned in the region to be processed. Furthermore, a corresponding device, a body produced in this way and a computer program product for carrying out the method are proposed.

Description

technical field [0001] The invention relates to a method and a device for the additive production of bodies as well as the bodies thus produced themselves. As an additive method, a powder bed method is preferably used. Background technique [0002] Additive production (also known as generative manufacturing, rapid prototyping, rapid manufacturing or 3D printing) has been an increasing focus of development and industrial applications since the late 1990s. Firstly for the manufacture of functional models and prototypes as well as tooling, since 2000 also for series production applications. Examples can be found especially in medical technology with the manufacture of dental tooth replacement restorations, individual bone replacement implants and complex instruments. In particular, the early implementation of series production is also achieved in the field of tool manufacturing by manufacturing injection molds with integrated cooling channels. Just before series production i...
