Key research area “Sustainable Materials, Processes and Products”
Climate protection and resource conservation is a central task of our society. The natural sciences and engineering can make their contribution by working on solutions for sustainable materials (metals, polymers and combined hybrids), on material-specific construction, joining and manufacturing processes, specific production and simulation processes or in the field of sustainable energy supply.
To cover this vast spectrum of research, Paderborn University bundles interdisciplinary research in mechanical engineering, the natural sciences and the electrical engineering faculties in its “Sustainable Materials, Processes and Products” research area.
Key technology lightweight design
Lightweight design is a key technology that offers huge resource-saving potential, in particular through combining state-of-the-art (production) techniques with high functionality.
Cross-faculty project teams at the Institute for Lightweight Design with Hybrid Systems (ILH) and Paderborn Institute for Additive Manufacturing (PIAF) conduct research into this complex topic.
Key technology additive manufacturing
Additive manufacturing is a key technology that can directly translate evolution through Industry 4.0 into reality. Through design freedom, it enables the creation of customised, resource-efficient and function-optimised lightweight structures.
At the PIAF and Direct Manufacturing Research Centre (DMRC), cross-faculty project teams collaborate with industry on research aimed at establishing additive manufacturing processes as robust industrial manufacturing processes.
Key technology sustainable energy technology
The transformation of the energy system toward sustainable electricity, heat and mobility generated by renewable energies is one of the central social challenges of the 21st century. The aim is to transform existing energy systems globally in such a way, that they are able to operate without fossil and nuclear energy sources and reliably supply humankind with cost-effective, sustainable energy.
KET contributes toward this goal through its research in sustainable mobility concepts, smart grids, energy efficiency as well as air pollution control and resource conservation.
A combination of applied and basic research
Applied research is driven forward in well-established academic and industry partnerships and complements first-rate basic research in the field of method or material development, for example, with research also carried out in long-term projects in a national and international alliance.
The researchers leverage the state-of-the-art infrastructure of the ILH and PIAF/DMRC in Paderborn and are part of an extensive research network.
Interdisciplinary research institutions
The aim of the ILH is to take a holistic view of lightweight design and to look at issues relating to the entire lifecycle of a component. Outstanding expertise in additive manufacturing as a special manufacturing process with high lightweight design potential is bundled in the PIAF and DMRC. At the Competence Center for Sustainable Energy Technology (KET), approaches and methods are being developed with the aim of achieving a sustainable energy supply for the electricity, heat, industry, and transport sectors.

The ILH is a central research institution of Paderborn University that bundles the expertise of eleven research groups from the disciplines of mechanical engineering, chemistry and physics to develop and research new hybrid systems made from various materials. Applied research gives rise to innovative lightweight design concepts. Prototypes and demos are designed in collaboration with the industry to test feasibility. Basic research is conducted into the cross-scale development of methods and materials.
In hybrid multi-material systems, high-performance materials, such as ultra-high-strength steels, are intelligently combined with carbon-fibre-reinforced polymers (CFRP). The prerequisite for the development of such material compounds is the analysis of material properties and interfaces and of the manufacturing processes with new material structures. To this end, the ILH boasts a broad team of researchers and a state-of-the-art infrastructure.

Selected projects in the research area
Additive manufacturing (AM) has the economic potential to complement conventional manufacturing processes, especially in the production of complex multi-material components. In order to fully exploit the advantages of optimised lightweight structures, several materials with different physical properties usually have to be used. Nevertheless, multi-material combinations from conventional processes are not transferable to AM due to residual stresses, cracks or thermal expansion rates of the different materials. Furthermore, geometric shape and position tolerances as well as recycling strategies for powder waste, reworked waste and the component itself are not yet defined. Based on the 3D printing processes PBF-LB and DED, the project "MADE-3D" (Multi-Material Design using 3D Printing) aims at the simultaneous development of processable, multi-material optimised alloys, the development of design concepts for multi-material structures with specific simulations for load cases and topology optimisations, as well as a comprehensive process adaptation. Alloy and process development is supported by advanced integrated computational material development approaches combining thermodynamics, microstructure and process simulations through machine/active learning, leading to shorter material development cycles. For bulk and powder materials, recycling of multi-material components through innovative approaches will promote the sustainability of multi-material additive manufacturing. This adaptation will lead to increased process reliability and speed and enable the spread of multi-material manufacturing throughout the industry. The project is being funded for the next three and a half years with around 6.7 million euros in the European Union's "Horizon Europe 2022" programme. The consortium, consisting of research institutions, market leaders in additive manufacturing, aerospace, automotive technology and start-ups, brings a broad range of international expertise: In addition to the management of the Paderborn University, project partners are: SLM Solutions; the Fraunhofer Institute for Casting, Composite and Processing Technology IGCV (all three from Germany); the University of the Aegean (Greece); f3nice (Italy); Exponential Technologies (Latvia); QuesTek Europe (Sweden); AVL List (Austria); Skyrora (UK); Safran Additive Manufacturing Campus; Commissariat à l'énergie atomique et aux énergies alternatives CEA (both from France); Amires(Czech Republic) and the Centre Suisse d'Electronique et de Microtechnique CSEM (Switzerland).

In 2014, the ILH successfully applied for the establishment of an interdisciplinary graduate programme for lightweight design (FK LEM), funded by the state of North Rhine-Westphalia. Graduates from the fields of mechanical engineering, science and sociology research and learn with and from each other. However, collaboration here is not only interdisciplinary but also transdisciplinary – the college stands out for the collaborative work of PhD students with players from the business community and civil society. This collaboration combines practical knowledge with research.
The first four-and-a-half-year funding phase was positively evaluated and extended. A key element of the second FK LEM funding phase is the cooperation with the new Department of Technology & Diversity (TD). TD taps into research approaches that draw on empirical social research methods. Hence, within the framework of this PhD programme, students acquire technology and sustainability research skills in addition to their technical and scientific training.
FK LEM was finished in2022.
