Until now, however, the use of additively manufactured tool inserts in injection molding was limited to thermoplastic processing. This led to a considerable restriction of application possibilities, as liquid silicones in particular, which are indispensable in many branches of industry such as medical technology, the automotive sector or electrical engineering, could not be processed without conventional metal tools. This is where the “ADDmold for LSR” research project comes in: By combining additive manufacturing and liquid silicone processing, the aim is to create a completely new way of producing silicone components. The advantages of cost-effective small-batch production and shorter product development cycles should also be available for LSR types in the future.

This innovation opens up far-reaching potential for industrial users in particular, especially small and medium-sized enterprises (SMEs). By using additively manufactured tool inserts for LSR, SMEs can react more flexibly to customer requests, reduce development times and adapt more quickly to changing market requirements. This helps to strengthen the competitiveness of these companies in the long term. It also creates new opportunities for customized product solutions that were previously not feasible for economic or technical reasons.

Ralf-Urs Giesen, Managing Director of UNIpace at the University of Kassel, emphasizes the importance of this research project: “This completely new approach to silicone processing will enable existing companies that already work with silicones to benefit significantly from the advantages of additive manufacturing. The ability to create tools quickly and cost-effectively will significantly increase the innovative strength of this industry.”

Alexander Schulmann, Research Associate Additive Manufacturing at SKZ, adds: “With this project, we are further expanding our expertise in the field of additively manufactured tools. We have already gained extensive experience with thermoplastics and now see great potential in revolutionizing the processing of liquid silicone in the same way.”

Interested companies have the opportunity to actively participate in the research project. The project partners invite companies to join the project committee free of charge. By participating, companies can not only benefit from the research results at an early stage, but also contribute their own requirements and use cases to the development.
