The development and optimisation of production facilities and manufacturing processes, as well as the analysis and qualification of materials, are key aspects here. Above all, quality requirements must be ensured through appropriate processes and methods. These aspects form the basis for the various research activities in this field.
As a large-scale research facility, our µCT is used in various fields of applied research. Its current applications are primarily in materials science, medical technology, joining technology, and energy technology.
In principle, the new possibilities of three-dimensional structural analysis and component measurement are available to all researchers at the University of Ulm. This technology is also incorporated into existing and new collaborations with our regional and national partners in research and industry.

Project description:
More than one million dental implants are placed every year in Germany alone. Although dental implants are considered a safe therapy, a realistic loss rate within the first 10 years is around 5%. Implant losses usually result in a long period of suffering and cause high individual and economic damage.
The overall aim of the project is to develop innovative testing, simulation and design concepts for safe dental implants to prevent complications and implant loss. This is to be achieved through an interdisciplinary approach in a team of engineers and doctors. Based on real, physiological stresses, medical-scientific cause hypotheses and an objective evaluation of existing implant systems, knowledge-based solution approaches for material selection, design definition and testing of new dental implants will be developed. A numerical load model with physiological-anatomical input variables is also intended to provide the treating implantologist with a tool for patient-specific selection and adaptation of the dental prosthesis.

Project description:
The overall objectives of the TiReZa project are to research the titanium alloy TNTZ-O and its production in a melting metallurgical process route as well as the development of a novel, reversible tooth replacement solution with a connecting element made of TNTZ-O.
At the THU, the mechanical-technological and tribological characterization of TNTZ-O is carried out, taking into account the composition, production route and microstructure formation as a result of thermomechanical treatment steps. The superelasticity of TNTZ-O is quantified in cyclic tensile tests. The previously unexplored fatigue behavior of the material is investigated in dynamic vibration tests in order to be able to evaluate the service life and reliability of the novel fastener and possible further applications. The findings will be incorporated into an FEM material model that reflects the unique material behavior and will be used for the purpose of digital product development. The development work of the company partners is supported by the evaluation of machining results from machining production and in the field of medical product testing.

Project description:
Arc-based additive manufacturing (WAAM) is becoming increasingly interesting for the additive production of large-volume Al components. Compared to SLM, the advantages of WAAM are the higher build-up speeds, the theoretically unlimited installation space, which makes the production of large components possible in the first place, and the significantly lower acquisition costs compared to SLM. In addition, the use of less expensive wire means that the material costs alone can be reduced by around 1/3 compared to the use of powder. Nevertheless, the WAAM of Al alloys for load-bearing structures has not yet been able to establish itself industrially. One reason for this is the high energy input during the build-up process, which reduces the mechanical properties. Furthermore, there are only a limited number of commercial wire materials available for processing Al alloys, which severely restricts the range of applications. By developing a process strategy based on two-wire technology, the aim is to produce high-quality functional Al components.

Project description:
The aim of the project is to develop a new MSG build-up welding process for wear protection applications that - compared to the conventional MSG process - more than doubles the deposition rate (≥ 12 kg/h) and reduces the build-up to < 5 %. The most important innovation is that, for the first time, it is possible to weld thin sheets (≤ 3 mm) with such high deposition rates with a significantly higher product quality. Due to the high energy input, the MSG process causes severe distortion, which is why it is currently only possible to process such thin components at low wire feed rates. To achieve the project objective, an external hot wire is used to decouple the energy and material input. Resource-efficient processing of fused tungsten carbide is also made possible. This improves the wear properties of existing coating systems, as higher WSC proportions (≥ 40 %) can be achieved. As a result, this innovative process strategy enables a reduction in material costs and process duration of around 50%.

Project description:
The motivation is to save considerable amounts of resources and CO2 emissions by achieving a significant reduction in the wall thickness of concrete components in reinforced concrete construction. This is to be made possible by establishing reinforcement mats made of fiber-reinforced plastic (FRP) with basalt fibers, which are clearly superior to the steel reinforcement mats commonly used today. The aim is to develop suitable basalt FRP elements and a manufacturing process for the reinforcement mats that is suitable for series production in order to be able to produce basalt FRP reinforcement mats in high quality and in the required quantities economically for the first time.

Project description:
A product goes through various stages from the idea to the time it is taken off the market. In research and practice, these phases are called the product life cycle. The aim of the Center for Applied Research (ZAFH) "Digital Product Life Cycle (DIP)" is to investigate how these stages can be fully digitally mapped and automatically executed. This project was set up as a research network at the universities of Ulm, Ravensburg-Weingarten, Reutlingen, Albstadt-Sigmaringen and the University of Stuttgart. It is supported by the state of Baden-Württemberg with funding of up to 1.5 million euros, half of which comes from the European Regional Development Fund (ERDF). The ZAFH is coordinated by Ravensburg-Weingarten University of Applied Sciences.
This means that all relevant product, process and resource-related aspects from the product planning, product development, production planning, production and use phases, plus the life cycle-related cost and energy balances, are integrated into an overall digital model. This is to be realized through innovative knowledge representation and knowledge processing using graph-based design languages. The aim is to accelerate innovation and achieve greater time and cost efficiency.
Ulm University of Applied Sciences is responsible for research in the field of production planning. The research focus is on the concept phase. In order to carry out the early planning process more efficiently and quickly, a model and rule-based configuration system is to be developed that also includes quality management and life cycle management requirements. A holistic approach will be pursued. The industrial implementation will initially be demonstrated using three use cases - a car front flap, a quadrocopter and a Segway - as examples.
An accompanying industry group, consisting of twelve companies from the region, will continuously evaluate the results and ensure direct application relevance. In addition, it is planned to teach the methodology of the knowledge-based digital product life cycle at the participating universities through joint teaching and further education courses.

The first step is to implement the machining of carbon fiber reinforced plastics (CFRP). This example will be used to develop and verify a scientific methodology for establishing the quantitative relationships between tool properties - material properties - machining process - machining parameters - edge zone influence - mechanical/physical properties of the edge zone, which can subsequently be transferred to other lightweight construction materials.
