SGL Group has identified 3D printing as future growth area for carbon and graphite material applications. Under the brand name Carboprint, the company is now introducing carbon and graphite components to the market that are created by Exone's 3D binder jet printing technology.
Wiesbaden/Germany — Collaboration between the companies is founded on SGL's knowledge in the raw material and powder preparation, as well as versatile technologies for post-processing carbon components. As a supplier for industrial binder jetting technology, Exone contributes its competences 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, the company's announced in a statement.
As the carbon body is initially porous after printing, post-processing, such as polymer impregnation or silicon or metal infiltration, play a major role. These additional processes allow the adjustment of versatile material properties to the specific application.
Thanks to the basic properties of carbon, such as high chemical stability and good electrical and thermal conductivity, first trial components are being developed for testing in applications in the areas of chemical apparatus construction and environmental technology. Concrete examples include heat exchangers and components for distillation columns, as well as pump components made of siliconized 3D-printed carbon. The new material has been presented officially to a larger application specialist audience for the first time at the Berlin Waste Management and Energy Conference in late January.
