METHOD FOR THE MECHANICAL TESTING OF A STRUCTURE FORMED AS ONE PART ON THE BASIS OF TEST PIECES GENERATED BY A 3D PRINTING PROCESS

摘要

The invention relates to a method for the mechanical testing of a structure (1, 10) formed as one part, comprising the following steps: a) identifying a sub-element (2, 11) in the structure (1, 10) formed as one part for generating a test element (3, 3′) that is intended to undergo mechanical testing, wherein the sub-element (2, 11) only represents a portion of the structure (1, 10) formed as one part, b) determining the spatial-geometrical structure of the sub-element (2, 11), c) generating the test element (3, 3′) on the basis of the spatial-geometrical structure of the sub-element (2, 11) and at least in part or in full by way of a 3D printing process, d) carrying out at least one mechanical test on the test element (3, 3′) generated. A further subject matter of the present invention is a method for modifying the structural design data of the structure (1, 10) formed as one part, in which the data of the mechanical testing that is obtained from the aforementioned method is used for a modification of the structural design data of the structure (1, 10).
