During the first years of the project, we worked on the entire value chain of additive manufacturing (AM) of ceramics for medical and aeronautical applications. Among the ceramics studied, we selected alumina, stabilized zirconia, silicon carbide and calcium phosphate.
Thus, we were able to develop and optimize innovative raw materials including powders and resins for the respective additive manufacturing technologies: Powder bed fusion (SLS/M) and VAT photopolarization (SLA)
With the help of the numerous industrial partners of the project, we have chosen to develop new 3D printers, after having identified the limitations and potential improvements to existing equipment for the SLS/M and SLA AM processes.
In addition to single-material samples, multi-material samples (metal / ceramic and ceramic/ceramic ) are studied from the point of view of their interfaces, manufacturing condition and their design & process constraints. (including samples obtained by SLA and SLS/M)
Regarding the development of tests, characterizations and standards, there are many works in progress where the members of the consortium are strongly involved (ISO and ASTM committees) in order to fill the absence of references and / or documents.
The modeling of different phenomena and other digital tools are also studied in this project despite their great complexities. Calculation codes are progressively optimized.
The creation of the network on additive manufacturing of ceramics is progressing and we hope to perpetuate beyond the project of public events like summer schools on the additive manufacturing of ceramics with the support of European science society
