Saving 500 tons of carbon dioxide with 3D printing of ceramics

Together with Zeiss, Schunk drives sustainability forward


When you need structural components made of ceramics that are as large as a human being, it can become a challenge. A challenge that was also faced by the Zeiss company. That's because the conventional manufacturing process, in which silicon carbide powder is pressed into a block and then milled, presented a major technical hurdle here. "A new idea was needed," says Stefan Unger, who is responsible for supply chain sustainability at Zeiss.

And this is exactly where Schunk came into play. Back in 2014, the experts at Schunk Technical Ceramics had developed a technology for processing silicon carbide - one of the hardest and most heat-resistant materials of all - using the 3D printing process. Called IntrinSiC, the process can produce components that were previously impossible with ceramics due to their complexity and size. The perfect method for Zeiss.

Collaboration pays off

"Zeiss was the ideal partner for us to further develop 3D printing," says Dr. Lars Schnetter, Managing Director of Schunk Ingenieurkeramik. The production of ceramic components using 3D printing is more flexible, more cost-effective, more resource-efficient and less prone to errors than conventional processes. "We were initially a bit skeptical if a supplier could even meet our demanding requirements with a printing process," reveals Stefan Unger. But the patience and trust of both parties paid off in the end.

Sustainable technology with great potential

Schunk Ingenieurkeramik and Zeiss have been jointly driving technological innovations since 2008, and with it another topic: sustainability. After all, 3D printing not only saves time, material and money: "By manufacturing ceramic components using the 3D printing process, Schunk could save around 500 tons of CO2 in 2022," confirms Schnetter. And Unger adds, "This technology has major potential since it can be transferred to other fields. What’s more, this is just the start."
