Schunk is the world leader in the 3D printing process of ceramic machine components made of RBSiC. With the patented IntrinSiC, ceramic components are manufactured additively in 3D printing. Regardless of whether the shape is very complex or the dimensions are very large, the ceramic components have the same high material properties as our well-known RBSiC.
Light, precise, hard, durable - ceramics can simply do more
Meeting the highest requirements
High-performance applications require high-performance materials. With the striving for lower weight, higher precision and durable load-bearing capacity, mechanical engineering is constantly pushing into new frontier areas. It's a good thing that our advanced ceramics are at home in precisely these areas.
Boundless freedom with 3D printing
Our patented IntrinSiC® manufacturing process combines the outstanding material properties of silicon infiltrated reaction bonded silicon carbide (RBSiC) with the process engineering advantages of 3D printing. Where shapes were once defined by manufacturing processes, today it's all down to your imagination. IntrinSiC® offers you design potential in new dimensions - even large and complex structures with undercuts and cavities can be produced in a single manufacturing step. The machine hours required for geometry milling in other processes are thus completely eliminated.
With IntrinSiC® you can significantly reduce your carbon footprint, making it easier to achieve your sustainability goals. Compared with conventional approaches, you save around 25% Co2 - and if you take into account the reusability of excess powder, the figure is as high as 70%.

Challenges in the high performance industry
High-performance machines require high-performance materials. Whether in aerospace, metrology or semiconductor technology, the quest is for minimized weights, increased load-bearing capacity and enhanced precision. When measuring machines reach the limits of the measurement accuracies to be realized, space applications require minimum weight at maximum load, or semiconductor systems enter the realm of atomic size during processing, ceramics are increasingly the only possible alternative to realize structural elements of the systems or individual process components.
Huge power up to the μ-range
In frame components and wafer vacuum chucks for precision machines in the semiconductor industry, ceramics is a key material.
It makes it possible to guarantee the position of the optics and sensors with the utmost precision so that the smallest nanometer structures can be achieved. Our patented manufacturing technology IntrinSiC® offers you advantages that are only available from Schunk: We are the only supplier who has been able to further develop the material in such a way that the required material properties are met and the component remains crack-free.
Your requirements are the measure of all things
Highest precision through the perfect ceramic - this is the best way to describe our partnerships with the metrology industry.
Our ceramic components made of RBSiC impress with unique material properties, both in standard products, such as quills, traverses and X-slides, Y-tables, as well as in individual frame designs or tool holders. Even complex designs and particularly large dimensions are possible - and you can always rely on very high rigidity, low thermal expansion and very good thermal conductivity.
Almost weightless into space
Weight reduction plays a major role in aerospace. We meet this requirement with bionic component optimization - it gives our ceramic components greater stiffness, functionality, dynamics and safety while keeping their weight low.
And quite incidentally, it also saves material costs. Thanks to their outstanding material properties, our reaction-bonded silicon carbide ceramics are used primarily in measuring systems, satellite structures and optical systems such as mirrors.
For solutions with the highest quality
With leading technologies in design, simulation, manufacturing and further processing, Schunk develops your components flexibly, tailor-made and quickly. Benefit from our more than 25 years of know-how and our strength as the market leader for reaction-bonded SiC.
From the inquiry to series production
Thanks to our IntrinSiC® 3D printing manufacturing technology, you can be sure that your components will be produced in a design-optimized manner and with short lead times. Here we show you step by step how such a development can proceed.
