International Syalons is now halfway through the three-year ToMax project and is involved in the development of lithographic additive manufacturing technology (L-AMT) for silicon nitride materials in close cooperation with consortium partners Lithoz.
Industrial know-how has been united across Europe for the EU funded Horizon 2020 project, in the fields of high performance light-sources, photopolymers and ceramics, life cycle analysis, system integration, software development, industrial exploitation, and rewarding end-user applications. The end goal of this project is to develop high throughput 3D-printers with excellent materials and energy efficiency.

Lithographic Additive Manufacturing Technology
The ToMax consortium is using resource-efficient, innovative production processes to develop energy-efficient L-AMT machinery, with a focus on manufacturing silicon nitride, alumina, and cermet parts with high shape complexity for aerospace and automotive engineering, energy efficient lighting applications and medical devices.
3D-printed Syalon 101 gyroid design
Ground-breaking results have been obtained so far in this project. Fully dense, extremely complex Syalon 101 and 050 grade parts with excellent surface quality have already been produced. Initial testing indicates the same mechanical properties as traditionally produced Syalon 101, as shows in the table.

The following video explains the superior thermal shock resistance of a 3D-printed Syalon 050 impeller. Here, the impeller remains intact after being quenched from 800°C into water at room temperature.
The focus for the rest of the ToMax project will be to refine the production process and work in close cooperation with end-users to develop complex new parts for applications where L-AMT is the only method of fabrication and Syalon is the ideal material.
International Syalons is extremely happy and encouraged by recent developments in the additive manufacturing of advanced ceramics. The company is looking forward to adding this fabrication technique to its proven production capabilities.
