Use of silicon nitride materials from additive manufacturing processes in earth observation instruments:
review of characterization tests and synthesis of development and achievement

The presentation will answer to the following questions: 1) Why technical ceramic materials are involved in an earth observation satellite? 2) Why additive manufacturing processes are interesting for the aerospace industry?
In a second time, a summary of the last 10 years development and achievement from first densified coupon to the first sintered demonstrator will be presented. The last results obtained on mechanical properties characterization and on quality inspection of the demonstrator will detailed which support the actual technological readiness level of the solution proposed by 3D Ceram Sinto on the 3D printing of the silicon nitride. To complete this presentation, the perspective and the development roadmap will exposed up to the objective to have au qualify solution for the manufacturing of flight part.

Strategies for improving the mechanical properties of 3D-printed ceramics: advances in materials and technologies
The presentation will address strategies for improving the mechanical properties of 3D-printed dense ceramics. These include: 1) the development of ceramics with increased defect tolerance (through phase transformation toughening) and 2) a further decrease in the size and number of processing flaws (by optimizing polymer-ceramic system formulation, printing parameters, and technologies). The presentation will also highlight other areas for improvement in ceramic additive manufacturing, analyzing the need to reduce processing time, energy consumption and environmental impacts (particularly with regard to chemical/thermal post-processing steps), to hybridize ceramic processing technologies and to develop approaches for in-situ repair and printing monitoring/control.
