To perform experiments on the Laser Megajoule (LMJ) [1, 2], the Laser Targets Department of CEA (commissariat à l’énergie atomique et aux énergies alternatives) builds up and develops targets with dimensional specifications ranging from nanometric to millimetric scale.

Additive manufacturing becomes an important process to realize target element or target assembly tools.
To match stringent specifications, accurate systems of characterization are used to characterize targets and manufactured micro-tools.

Micro X-Ray computed tomography is a powerful instrument of control and acquisition of information for manufactured products. This technology can be useful in the validation of geometric parameters which are difficult to obtain with other metrology systems. It allows characterizing internal defects volume and geometry. The obtained tomographic volume is analysed with a post processing visualization tool.

This works highlights improvements of the characterization of 3D printed micro-tools, with complex shape by computed tomography. Results are presented and detailed.
