Lithoz, a specialist in ceramic 3D printing, is presenting the new CeraFab S320 printer at RAPID+TCT 2025 in the USA. Compared to the established S65, this offers a five times larger build platform and enables the high-precision production of medium-sized ceramic components. With a resolution of 60 micrometers and the newly introduced Digital Surface Enhancement software, serial production processes can be carried out more efficiently and with greater accuracy.
An outstanding application example is the production of SeparonicsTM ceramic filter membranes for lithium extraction by the company Evove. These membranes have precisely defined pore structures that reduce the pressure required for filtration and at the same time double the lithium yield. With a diameter of 100 millimeters and a length of one meter, the printed modules are the largest ever produced using Lithoz CeraFab technology. Compared to conventional polymer filters, this technology enables 80 percent higher water recirculation and reduces CO2 emissions thanks to lower energy requirements and optimized logistics processes.
Lithoz will also be demonstrating the production of 15-inch alumina gas manifold rings in cooperation with Alumina Systems. On a single build platform of the CeraFab S320, 20 segments could be printed. Dr. Holger Wampers, Managing Director of Alumina Systems, explains that higher geometric stability was achieved through additive manufacturing. The combination of high precision and ceramic material properties means that the service life of the rings could be increased from one to nine months compared to metallic variants.
In addition to medium-sized components, Lithoz will also be demonstrating the possibilities of ceramic 3D printing in the micrometer range. Bosch Advanced Ceramics will be presenting ceramic insulating sleeves produced in large series on a CeraFab S65. With a wall thickness of just 90 micrometers and a tolerance of ± 30 micrometers, 1,400 of these high-precision components were produced for a medical technology customer on a single build platform. This demonstrates the high reproducibility of Lithoz technology, which is of interest for both industrial and medical applications.
