Development and implementation of analysis methods for the experimental validation of gravimetric density measurements on additively manufactured components

Aim of the joint research project is to develop an innovative system for the automated, non-destructive determination of the density of additively manufactured components, based on the gravimetric principle, especially for industrial quality assurance processes. For this purpose, infiltration media, which are required for gravimetric density measurement, are optimized with regard to rheological properties, wettability and long-term stability. In addition, the project examines analysis methods for determining the density of additively manufactured components for correlations to the new automated system, which are currently considered as industry standards (microscopic analysis of cross-sections, micro-CT analyzes etc.). Investigations are carried out on additively manufactured components based on metal, ceramic and plastic.

The new system enables an automated and non-destructive determination of the component densities with very high accuracy, which is particularly suitable for industrial quality assurance processes and production-integrated measurements. The quality assurance with regard to density and porosity of additively manufactured components is thus highly precise and cost-effective. To make this possible, knowledge of the technological fundamentals of gravimetric buoyancy measurement as well as the rheological properties of the infiltration media used are essential. To validate the new system, comparisons with established quality assurance processes are necessary in order to form the basis for a technically mature and attractive product. As part of the research project, research and development work on these priorities will be carried out together with the research partner.
