KYOCERA Fineceramics Europe has introduced a process for the additive manufacturing of components made of silicon carbide (SiSiC) at its Selb location in Germany. As a result, the company is expanding its portfolio in the technical high-performance ceramics sector and creating new possibilities for the production of complex, highly resilient components.
“The introduction of additive manufacturing is a milestone for our company,” says Dr Carsten Rußner, President of KYOCERA Fineceramics Europe GmbH. “It brings up new potential for us in terms of development and application as well as strategic positioning in the market.”
3D printing of components made of SiSiC
Silicon-infiltrated silicon carbide (SiSiC) is a high-performance ceramic material with exceptional mechanical strength, thermal conductivity, rigidity and high wear resistance. SiSiC is ideal for demanding areas of application such as aerospace, the semiconductor industry and industrial production, particularly due to its barely measurable thermal expansion. Kyocera processes both StarCeram Si, which is used for conventional processes, and StarCeram AM-Si, which was developed for 3D printing, independently – both materials are characterised by comparable material properties.
With the progress of additive manufacturing technologies, 3D printing has proven to be a pioneering method for the production of complex SiSiC components. Compared to traditional shaping processes such as isostatic pressing, slip casting or film casting, additive manufacturing offers significantly greater design freedom and shorter development cycles. For example, topology-optimised components can be produced, which can lead to an enormous reduction in weight. Ceramic 3D printing therefore offers the ideal solution for demanding designs where conventional techniques reach their limits.
Thanks to this process, Kyocera offers its customers a broad portfolio of durable, resilient and precise components, from prototype development to series production.
“This advancement is the result of intensive research and development work,” explains Sarah Diener, Team Leader for Additive Manufacturing. “We look forward to creating added value for our customers through the production of complex component geometries.”
The advantages of additively manufactured components made of technical ceramics
Complex geometries
Additive manufacturing enables the implementation of highly complex geometries that cannot be realized using conventional processes. These include curved structures, undercuts and bionic structures. The more complex the geometry, the more the advantages of the process become apparent.
Design consulting
Kyocera offers comprehensive design consulting for the optimisation of component geometries and the implementation of topology-optimised structures. In dialog with the customer, the component weight can be reduced or the performance of the components increased. Thanks to close cooperation with the company’s own design centre, tailor-made solutions are created that are optimally adapted to the respective application.
“Additive manufacturing enables us to react flexibly to dynamic market requirements,” emphasises Dr Nikolaos Katsikis, Director Research & Development. “We see great added value for our customers, particularly when it comes to large and complex components – especially when we are able to provide optimisation support through our design consulting.”
