Sinto Advanced Ceramics Expands 3D Printing Material Offerings

New Material Additions

Sinto Advanced Ceramics Europe GmbH has officially added aluminum nitride (AlN) and silicon nitride (Si₃N₄) to its lineup of materials for additive manufacturing. Both non-oxide ceramics are now accessible for development projects, prototypes, and industrial applications, following internal evaluations and initial project implementations.

The first publicly displayed parts using these materials were showcased at the ESA Industry Space Days 2026, featuring aluminum nitride sleeves, a silicon nitride hold-down component, and an aluminum nitride heat exchanger. This expansion complements Sinto’s existing selection of high-purity oxide ceramics, including alumina and zirconia, aimed at providing engineers with a broader range of material choices.

Distinct Properties for Different Applications

Aluminum nitride is characterized by its electrical insulation properties combined with high thermal conductivity, making it suitable for thermal management and power electronics applications. Conversely, silicon nitride is noted for its mechanical strength and thermal shock resistance, positioning it as a reliable choice for demanding mechanical applications.

Sinto Advanced Ceramics emphasizes that the selection of materials should be application-driven. Dr. Malte Hartmann, Head of Research and Development, stated that the choice between aluminum nitride and silicon nitride depends on the specific requirements of the application.

Focus on Process Control

Sinto highlights that successfully integrating new ceramics into industrial additive manufacturing involves more than just having the right materials. The company is committed to controlling the entire process chain, from printing to quality assurance. This ensures that any new material meets the necessary specifications without introducing defects during production.

Frohwald Heller, Head of Sales, noted that Sinto’s role extends beyond that of a contract manufacturer, as they aim to collaborate with customers to identify the best solutions based on their specific challenges. This collaborative approach may lead to the discovery of new materials that could be optimal for certain applications.

Meeting Market Demand

Sinto’s strategy reflects the increasing demand for advanced ceramic materials in various industries, especially for thermal management applications. As competition in the market grows, the focus is shifting from merely having available materials to ensuring that their production is reproducible and meets rigorous standards. This aligns with trends observed by companies like Lithoz, which reported significant growth in ceramic material revenue, particularly for aluminum nitride.

By prioritizing qualified and reliable production processes, Sinto aims to position itself as a key engineering partner capable of delivering non-oxide ceramic parts that meet the evolving needs of the industry.
