Precision in perfection – ceramic solutions from Schunk for use in space
Discover even more of Schunk's innovative solutions for satellite technology now. Learn how high-performance ceramic materials and 3D printing technologies are setting new standards in precision, stability, and lightweight construction.
Why Silicon Carbide Is Gaining Ground in Aerospace
Space is a tough environment. Satellite components must withstand extreme temperature changes, vibrations during launch, and function reliably for years without maintenance. This is where silicon carbide (SiC) shows its strengths.
It offers low density, high stiffness, and remains thermally stable under changing conditions. Silicon carbide can also be processed to achieve highly precise optical surfaces, making it the ideal material for applications like satellite mirrors and structural parts in optical systems.
Design Freedom Meets Precision: The Advantage of Ceramic 3D Printing
Using its proprietary IntrinSiC®3D printing technology, Schunk can produce large and complex ceramic components with exceptional precision. This approach offers:
Greater design flexibility
Weight reduction, which helps lower launch costs
Shorter development cycles with consistent quality
Schunk is currently collaborating with a leading European space company on mirror substrates up to 1.55 meters in diameter. A prototype has already been manufactured for the European Space Agency (ESA).
In-House Expertise Across the Full Manufacturing Chain
One of Schunk’s key strengths is its fully integrated value chain. All critical steps – from raw materials to final finishing – are handled within the Schunk Group:
Optical coatings supported by partners such as Dynavac
This tight integration ensures short lead times, consistent quality, and process reliability – all critical factors in aerospace manufacturing.
For the Next Generation of Optical Systems in Space
Schunk’s 3D-printed ceramic components are ideal for space-based systems where performance, reliability, and low mass are essential – including:
Satellite mirrors for optical and infrared applications
Support structures for sensors and instruments
Lightweight components for scientific and defense missions
Combining advanced ceramic materials with additive manufacturing opens new possibilities for performance-optimized designs that meet the stringent demands of space missions.
Conclusion: Precision and Innovation for the Demands of Space
Modern satellite systems rely on components that are as smart as they are resilient – lightweight, stable, and precise. Schunk Technical Ceramics combines deep expertise in technical ceramics with advanced 3D printing and an integrated production approach to deliver solutions tailored for orbit.
From Willich to space – engineered for performance, built to last.
