Additive Manufacturing in Electronics: Insights into Research at Silicon Austria Labs – Interview with Lukas Rauter

Silicon Austria Labs (SAL) is an extra-university research center specializing in electronics and software-based systems, established in 2018. With locations in Graz, Villach, and Linz, SAL focuses on key technologies in the fields of microsystems, sensor systems, power electronics, intelligent wireless systems, and embedded systems. Through close collaboration with industry and academia, SAL conducts application-oriented research across the entire value chain. One of its key research areas is additive manufacturing, particularly 3D printing for electronic applications. In an interview with 3Druck.com, scientist DI Dr. Lukas Rauter explains the role of additive manufacturing in electronics and sensor development, its advantages, ongoing research projects, and future technological advancements.

At the location in Villach, Austria, SAL operates the “Printed and Flexible Electronics” laboratory, which focuses on the research and development of printed and flexible electronic components. The laboratory utilizes various printing technologies, including inkjet, screen, aerosol jet, and electrohydrodynamic (EHD) printing, enabling high-precision structures with resolutions down to the micrometer scale. These methods allow for the direct deposition of complex electronic circuits onto flexible or three-dimensional substrates, facilitating the production of lightweight and adaptable components for various industries.

One of SAL’s current research areas is the integration of additive manufacturing into the development of energy-autonomous sensor systems. By using printed electronics, sensors can be embedded directly into components, reducing weight and material usage. Additionally, SAL is working on optimizing functional inks for 3D printing to further improve the electrical conductivity and stability of printed structures.

By integrating additive manufacturing technologies into its research, SAL contributes to the development of new approaches for the production of electronic components and promotes innovative solutions for various industrial sectors. As a member of the AM Austria technology platform, which promotes and supports the additive manufacturing industry, SAL is also involved in the further development of these technologies and works closely with industry and science.

Interview with Lukas Rauter

In an interview with 3Druck.com, DI Dr. Lukas Rauter, a scientist from the Advanced Sensor & Electronics Technologies (ASET) research group at Silicon Austria Labs, discusses the significance of additive manufacturing for the development of printed electronics and sensors, as well as its advantages over conventional manufacturing methods. He also provides insights into SAL’s current research projects and discusses future technological developments, including advancements in printing technologies, sustainable materials, and the integration of printed sensors into the Internet of Things.

What role does additive manufacturing play in your research and development, and what advantages does it offer over conventional manufacturing methods for electronic components and sensors?

Additive manufacturing is a key element of our research and development in the field of printed sensors and electronics. Unlike conventional subtractive manufacturing methods, it enables resource-efficient production, as only the required material is deposited. Furthermore, electronic components can be printed flexibly onto various substrates such as paper, wood, or bioplastics, enabling new applications and environmentally friendly solutions. The fast and cost-effective manufacturing process allows for the development of customized sensors and electronics for a wide range of applications.

What current projects is SAL working on in the field of additive manufacturing, and in which industries and application areas do you see the greatest potential for this technology?

SAL is currently working on several projects related to printed electronics, including sensors for environmental monitoring, smart textiles, and industrial applications, as well as printed displays and OLEDs. One of the most promising fields is medical technology, where printed sensors can contribute to continuous health monitoring. Printed sensors also offer significant potential in the construction industry, the automotive sector, and Industry 4.0, for example, in real-time monitoring of material properties or production processes. Additionally, electronics based on renewable raw materials and biodegradable components could help create more sustainable products and reduce electronic waste.

What technological developments and innovations do you expect in the coming years in the field of additive manufacturing for electronics and sensors? What new applications or material advancements could shape the industry?

In the coming years, we anticipate advances in printing technologies and functional materials that will enable even higher precision and improved electrical properties. New conductive and semiconductive inks could further enhance the performance of printed electronics. A key trend is the development of bio-based or recyclable electronics to promote sustainability in digitalization. Additionally, printed sensors are increasingly being integrated into the Internet of Things (IoT), creating new applications in smart manufacturing, health monitoring, and environmental technology. The development of printed electronics embedded in components—even in three-dimensional forms—will drive miniaturization and lead to significant reductions in weight, cost, and complexity.

What initiatives and projects is SAL pursuing as a research center and member of AM Austria to advance additive manufacturing technology?

SAL is actively involved in advancing additive manufacturing through interdisciplinary research projects and collaborations with industrial partners, universities, and other research institutions. As a member of AM Austria, we are working on innovative solutions to improve the performance and sustainability of printed electronics. Through projects with partners from various industries, we are driving the application of printed sensors in industrial, medical, and sustainable electronics. Additionally, SAL promotes knowledge transfer by supervising master’s and PhD students and organizing workshops.
