Particle Size Distribution

  • Covering entire size range of metal additive manufacturing powder, from submicron to millimeter particles, in accordance with ISO 13222
  • Broadest measurement range for multi-modal samples
  • Validated accuracy and repeatability using proprietary reference sample and analysis


  • Particle morphology reported to ASTM F1877
  • Save high resolution images of every particle
  • Relocate ‘deformed’ particles for detailed morphology and chemical analysis

Foreign Particle Detection

  • Integrated EDX spectrometry for identification of few foreign particles among many thousand particles
  • Quickly identify foreign particles with default classification recipes for common powders
  • Post-process and data mine without need to analyze sample again

Finished Parts Analysis 

  • Automated recipes for unattended analysis of finished parts
  • Detect and characterize voids and inclusions in finished parts
  • Review images of all characterized voids and inclusions
