Nowadays, simple cost effective and resource-efficient production of components with complex geometries is indispensable. This can be achieved by additive manufacturing (3D printing), since it is a fast, efficient and innovative. A wide variety of materials can be used for 3D printing, including polymers, metals, etc. In applications where these materials reach their limits, the strengths of carbon and silicon carbide become clear. Our materials are specialized for applications with:
- High temperatures
- Corrosive media
- Abrasive environments
- High hardness requirements

Due to the unique material properties of carbon, our 3D printed casting cores enable higher surface quality through low wettability with molten metals. In addition, increased casting efficiency is achieved through lower thermal heat capacity and higher thermal conductivity compared to conventional sand casting cores.
In high-temperature metallurgy, production tools such as crucibles are exposed to extreme conditions. Especially in these applications, we combine the extraordinary material properties of ceramics (e.g. very good temperature stability) with the design freedom of additive manufacturing. These tailor-made solutions enable our partners to increase their process efficiency. Due to the chemical resistance and durability of our materials, the operating costs can be reduced.
Due to its abrasion and corrosion resistance, silicon carbide is an ideal material to produce static mixers. To minimize the pressure loss and increase the efficiency of the mixers, their geometry can be optimized by our numerical simulations. The innovative geometries can be produced solely by 3D printing.
In topology optimized components, material is only applied in areas where it is required. Whereas conventional manufacturing methods may be limited, 3D printing allows an efficient production of such components. As a result, not only weight but also production costs can be reduced.
Carbon (CARBOPRINT) or silicon carbide powder (SICAPRINT) is used for 3D printing with binder-jetting technology as raw material.
Advantages of using carbon and silicon carbide:
- Low density & weight
- Chemical resistance
- High thermal stability
- Low thermal expansion
Our finishing options (e.g. heat treatment, infiltration with carbon, polymers or liquid silicon) enable us to tailor the material properties of the end product to your individual requirements.
