Lithoz Has Installed CeraFab S65 Printers to Build Casting Parts for Safran Aircraft Engines

• Safran Aircraft Engines have acquired three CeraFab System S65 printers from Lithoz to build up serial production of casting parts for future generation aircraft engines.
• The CeraFab printers have been installed at Safran Aircraft Engines near Paris
• Ultra-precise Lithoz LCM printers as key technology enable industrial production of highly complex casting cores meeting cooling requirements of future aircraft engines.

07th October 2025: Vienna, Austria. Lithoz, the global market leader in ultra-precise ceramic 3D printing, has announced the installation of three CeraFab System S65 printers at Safran Aircraft Engines Gennevilliers, near Paris. This investment will enable the French engine manufacturer to build up the serial production of complex casting cores at industrial scale, meeting the high cooling demands of next-generation aircraft engine turbine blades.

Lithoz’s ultra-precise Lithography-based Ceramic Manufacturing (LCM) technology in combination with the ceramic formulations, which were co-developed between Lithoz and Safran in the last couple of years, led to a reliably repeatable and scalable solution which showcases a groundbreaking adaptation of Lithoz LCM ceramic 3D printing in the aerospace industry.

Increasing the high pressure turbine inlet temperatures is key for future engine generations, meaning that the components must withstand those increased temperatures. This can be achieved by implementing more complex cooling channels during the casting process used to manufacture the turbine blades. With its operational and resource-based efficiency, Lithoz’s ultra-precise LCM technology has reached a level of complexity for casting cores previously unattainable with traditional ceramic manufacturing processes.

Safran Aircraft Engines chose this equipment in particular for its performance and short production time. The ergonomics and software functions are adapted to production and meet aeronautical traceability requirements. Finally, the high level technical skills and quick response capabilities of Lithoz teams have been major assets to respect the initial target planning and reach the success of this project.

Johannes Homa, Lithoz CEO: “The installation of these three CeraFab S65 printers is a true milestone for both Lithoz and the aerospace industry. As Safran Aircraft Engines move forward to further develop their serial additive manufacturing process for ceramic casting cores, Lithoz remains strongly committed to providing our constant support in this important project.”
