Micro-CT in Additive Manufacturing

Micro-CT visualisation

Modern production processes including hot isostatic pressing (HIP), additive manufacturing and metal injection molding and manufacturing techniques involving metal powders.

Micro-CT is used to determine the morphometry of particles in powder metallurgy, for demanding production processes. As a non-destructive technique, it’s also extremely useful for looking inside objects in failure analysis and final parts inspection.

Characterise samples from µm to cm scale in minutes


Micro-CT (also known as XRM or X-Ray Microscopy) is widely used in areas including:

CAD Comparison

Compare manufactured parts with CAD models.

  • Measure deviations in 3D, on both internal and external surfaces
  • Set pass/fail tolerances at pre-defined inspection points

Parts Inspection

  • Examine failed products
  • Analyse cracks and voids
  • Check contact areas at interfaces
  • Investigate defects
  • Examine reactions to stress and temperature with in-situ stages


Quantitative determination of :

  • Porosity & inclusions
  • Volume fractions
  • Orientation
  • Dimensions
  • Surface
  • Angles

Metal Powders

Quantitative analysis of metal powders – measure parameters including:

  • Sphere size distribution
  • Sphericity
  • Packing
  • Porosity
  • Surface to volume ratio
  • Surface roughness
  • Convexity
  • Form factor

Micro-CT Cooling Stage

Cooling and Heating Stages

Study how parts and materials react at elevated temperatures up to 85°C and down to 30-40°C below ambient.

Material Testing Stages

Combine micro-CT imaging with in-situ tensile and compression testing. Loading curves are displayed on screen in real time
