Method for determining properties of three-dimensional objects

Abstract

The invention relates to a method for determining properties of three-dimensional objects that have been produced by a generative method, in particular by a thermal generative method. The problem solved is that of providing a nondestructive test method by which the density of such objects can be determined and possible component defects can be identified. This is achieved by firstly completely immersing the three-dimensional object in a dyeing liquor, removing it from the dyeing liquor after a defined residence time, then washing it off, drying it and exposing it to a vacuum and subsequently subjecting it to an image-analytical evaluation by determining the intensity of the colouration by apparatus technology, wherein an assessment with regard to density and component defects of the three-dimensional object is effected by a comparison of the image-analytical characteristic values of colouration and reference data stored beforehand by computer technology.
