CARBOPRINT®, a material that integrates carbon and graphite for additive manufacturing production

ExOne and SGL Group recently launched on the market CARBOPRINT, a material that combines both carbon and graphite components to enhance additive manufacturing processes. The two companies aim to start component development and production with selected customers.


The material has been made using ExOne’s 3D binder jet printing technology. The two companies also combine the specific properties of their materials:

The truth is that the carbon body is initially porous after printing, therefore, polymer impregnation or silicon or metal infiltration from SGL Group, was of great importance in the creation of the material.

Each party brings their expertise: SGL Group offers extensive knowledge on raw material and powder preparation, as well as versatile technologies for post-processing carbon components. As the leading supplier for industrial binder jetting technology, ExOne contributes its competencies in 3D printing. This technology enables not only the production of small prototypes, but also efficient serial production and fast development of customer-specific solutions”, explained Rick Lucas, ExOne’s Chief Technology Officer.

The next step?

Following the initial material development study, the company will now proceed with first trial components in a wide range of applications. Specific examples include heat exchangers and components for distillation columns, as well as pump components made of siliconized 3D-printed carbon.
