Kyocera presents conventionally and 3D-printed components made of high-performance ceramics at Space Tech Expo Europe 2025

Kyoto/Esslingen, 13^th November 2025. KYOCERA Fineceramics Europe GmbH is presenting its latest developments in the field of high-performance technical ceramics at this year's Space Tech Expo trade fair taking place in Bremen, Germany. The focus is on the materials Fine Cordierite and silicon-infiltrated silicon carbide (SiSiC). Furthermore, Kyocera is showcasing new approaches in the additive manufacturing of ceramic components.

Fine Cordierite & SiSiC – versatile and highly precise to use 

Fine Cordierite is characterised by an extremely low coefficient of thermal expansion and remains dimensionally stable even under extreme temperature fluctuations. Thanks to its high rigidity, it allows weight reductions of up to 70 per cent compared to glass. Due to these mechanical properties, Fine Cordierite is used for structural components that require reliable performance under extreme conditions. 

Besides Fine Cordierite, silicon-infiltrated silicon carbide (SiSiC) has established itself as a versatile high-performance material. SiSiC is one of the most powerful technical ceramics and is characterised by outstanding mechanical strength, high rigidity, thermal stability and excellent wear resistance. Thanks to its extremely low thermal expansion, SiSiC is particularly suitable for applications with the highest precision requirements – such as aerospace, semiconductor manufacturing or industrial production processes. The proprietary joining and manufacturing technology enables the production of complex, gas- and water-tight components with fine structures measuring less than 1 mm. Even large-area, monolithic components measuring up to 950 × 950 × 650 mm can be produced. Kyocera manufactures both StarCeram^® Si, which is used for conventional manufacturing processes, and StarCeram^® AM-Si, which is optimised for additive manufacturing. Both variants offer an almost identical property profile and therefore guarantee consistently high material quality – regardless of the manufacturing process.

Additive manufacturing offers new design and construction possibilities 

3D printing of SiSiC components offers a significantly higher degree of design freedom for complex structures and enables the implementation of topology-optimised designs that lead to a noticeable reduction in weight. It is therefore the ideal solution for demanding designs where conventional processes such as isostatic pressing, slip casting or film casting reach their limits. A two-stage manufacturing process is used to produce high-precision, durable components that are suitable for both prototypes and series production. During the process, a green body is initially created from silicon carbide powder and polymer binder using the binder jetting method. Afterwards, it is infiltrated with molten silicon, which reacts with the remaining carbon to form the final SiSiC structure.

The production process was particularly developed for large-volume and complex components. By eliminating green machining, reducing programming effort and eliminating tool production, short production times are possible. The more complex the geometry (e.g. undercuts, curved surfaces, bionic structures), the more apparent are the advantages of additive manufacturing over conventional processes.

Additionally, Kyocera offers design consulting and support in optimising component geometries. By working closely with the company's own design centre, it is possible to develop solutions that are precisely tailored to the respective requirements.
