Embodiment Construction

[0029] All the figures do not show the invention to scale, but only schematically and only essential components thereof are included here. The same reference numbers correspond to elements of the same or similar function.

[0030] During the powder-based additive manufacturing of the component 1 , which is not further described, it is necessary to simultaneously construct the form of the support wall 2 using suitable computer-generated CAD data and by means of the usual manipulations for a person skilled in the art with the aid of suitable computer software. support structure. Suitable powders, for example made of metallic materials, are used as structural material for the component 1 and the support wall 2 .

[0031] Overall, a plurality of support walls 2 spaced apart from one another and not connected to one another are provided for the component 1 . Here, the length 3 of the individual support walls 2 is considerably greater than their height 4 and width 5 . The support...

Abstract

The aim of the invention is to enable, in a particularly simple manner, the removal of a support structure (2) for a component (1) produced by additive manufacturing. This aim is achieved, according to the invention, in that the free end (9) of the support structure (2) is repeatedly deflected from a starting position (16) to a deflection position (17) by application of a bending torque, in such away that the support structure (2) experiences working hardening due to plastic deformation at a defined location, in particular at the fixed end (8) of the support structure, until the support structure (2) fractures at the location during a further deflection.

Description

technical field [0001] The invention relates to a component produced by means of additive manufacturing including a support structure. Furthermore, the invention relates to a method for constructing a support structure and a method for removing a support structure. Furthermore, the invention relates to a bending device for removing a support structure. Background technique [0002] Additive manufacturing is understood here in particular to mean the layer-by-layer construction of three-dimensional objects using a digital computer model, in particular by selectively reinforcing layer-wise applied structural materials. The structural materials used for this purpose can be present, for example, in powder form. Examples for such a manufacturing method are laser sintering, mask sintering, and the like. [0003] Many additive manufacturing methods require support structures (“supports”). The support structure is usually connected to the component on the one hand and to the cons...
