Technology
Production & Control
A controlled production chain, from raw material to finished part.

Quality control throughout the entire production chain

Continuous metal powder characterization by sampling
- Measurement of chemical composition ASTM F3184 norm
- Measurement of powder granulometry ASTM B822 norm
- Measurement of coulability, apparent and tapped density, ASTM B213, B212, B527

Layer-by-layer monitoring of production
- 3D printed machine monitoring data (oxygen content, protective gas pressure, substrate temperature, etc.)
- Pre- and post-laser melting images of each layer
- Test specimens
- Manufacturing report

Characterization and inspection of manufactured parts
- Metallographic characterization of test specimens
- Density measurements
- Mechanical tests
- Non-destructive testing (NDT)
Qualification and certification of AM3L products for regulated fields
Based on its CEA expertise and background, the development of AM3L metamaterials meets the certification requirements of regulated fields such as the nuclear energy industry.
AM3L shock absorbers are already being used in full-scale tests for nuclear waste storage.
