Additive manufacturing: characterising materials

Area of expertise

Metallic materials

caractériser les matériaux

To properly control the additive manufacturing process, a mechanical, physical and chemical characterisation of the metallic materials obtained is required.


For metallic products obtained after additive manufacturing, you want to:

  • Identify reliable analysis and characterisation methods,
  • Analyse the structure and microstructure of your metallic materials and perform a characterisation in terms of grain size, inclusion cleanliness, presence of phases, porosity, etc,
  • Assess the mechanical behaviour of your products,
  • Understand the degradation or aging phenomena,
  • Implement the appropriate heat treatment or the optimum surface treatment,

A team of specialists with specific resources to characterise metallic materials produced by additive manufacturing

  • Characterisation of powders (grain size, rheology, etc.)
  • Macroscopic, microscopic and fractographic examinations using instruments such as binocular magnifiers, optical microscopes (1,000 X magnification), SEMs (Scanning Electron Microscopes) equipped with microanalysis probes
  • Determination of density
  • Microhardness measurements, hardness profiles (Vickers, Brinell, etc.), determination of the depth decarburisation
  • Standard chemical analyses and specific methods
  • Laboratory simulation: accelerated aging (corrosion, wear / friction, fatigue, creep)
