The University of Hamburg (hereinafter "uhh") is a university of excellence with more than 43,000 students and around 6,000 employees, one of the strongest research universities in Germany and at the same time one of the largest training institutions in northern Germany. With its concept of the "flagship university" in the Hamburg metropolitan region, it maintains innovative and cooperative connections with scientific and non-scientific partners. It produces the future-oriented social goods of education, knowledge and the exchange of knowledge for the location - but also nationally and internationally - with the main goal of sustainability. The University of Hamburg, as the central procurement office for the Hamburg University of Applied Sciences (haw Hamburg), is conducting an open procedure for a delivery service. The aim is to purchase and deliver a complete, immediately operational system for computer tomography - for the Layer project - increasing the service life of additively manufactured (waam) components using hybrid manufacturing processes. The third-party funding provider has approved €280,000.00 net for the procurement and commissioning of the system. As part of the project, methods are being developed to create a fine-grained and quasi-isotropic structure during production. Furthermore, different processes for robot-based in-situ surface processing are being developed in order to eliminate the downstream step of surface processing or to reduce the effort involved. As part of the planned research project, process parameter windows must be developed for the production of "fault-free" samples and demonstrators. In addition to additive manufacturing, process parameter windows must be developed for surface processing and structure optimization. The service life depends in particular on the type, shape and location of the irregularities in the additively manufactured component. Validating the process parameters by analyzing micrographs is not sufficient, since a micrograph only represents the state of one plane. Although it is practically possible to produce and evaluate multiple grinding planes, there is a risk that important areas will be ground away or not exposed during preparation. It is therefore necessary to analyze the samples as a whole using a CT system. Based on the examination carried out, parameters can be developed that lead to components with permissible irregularities. This cycle, consisting of sample, welding and testing, must be carried out as precisely as possible in order to be able to work out the broadest possible parameter set.
