Innovation center for 3D-printed sand cores

Since June 2018, our iron casting plant in Leipzig (DE) has had its own innovation center with a team working on additive manufacturing and its application for sand cores used in iron casting.

Speeding-up your sandcasting process

With the serial production of 3D-printed sand cores for sandcasting processes, we are your reliable partner providing know-how and state-of-the-art technology in the heart of Europe.

The innovation center for additive manufacturing was opened at our iron casting location in Leipzig (Germany) in 2018. Our customers not only save time and money on prototypes and spare parts, but also benefit from optimized production processes and virtually unlimited freedom of design.

Your reliable partner for prototyping

By using additive manufactured prototypes, you get the geometries of early design stages which are produced already close to serial conditions. This way we can test, and improve before the actual serial production starts. 

Unconventional design needs unconventional technology

The highly complex design of 3D-printed sand cores is crucial for the complex design of a cast solution. It offers completely new design possibilities for hydraulic applications as well as truck, machine and engine parts. 

In 2018, GF Casting Solutions agreed on a long-term development partnership with ExOne to benefit quickly from the future development of the technology and to bilaterally improve the production processes.

Your advantages

The 3D printing process works in the same way as an inkjet printer. Instead of spraying ink onto paper, though, the print head sprays a liquid binder onto a layer of sand – according to a precisely predefined geometry. The binder is then sprayed onto the next layer and so forth. This continues layer by layer until the desired sand model is completely built up. In this way, a model digitally designed on a computer gives rise to a three-dimensional solid object. For the actual iron casting, the cores are then placed in fireproof molds.
