An intelligent multisensor‐based build quality monitoring system for Selective Laser Melting Process (SLM)

Industry Sector

AM Technology


  • To develop an enhanced process monitoring system to ensure parts’ quality, repeatability, and consistency.

  • Future commercialisation opportunity: deployment into IDI’s future metal printers, licensing to current SLM OEMs.

Innovation Applied

  • Deployment of multisensors (acoustic signal and NIR images) and development of image processing algorithm [software and process innovation]

Key Benefits

  • Enable enhanced and more accurate in-situ process monitoring system that combines multisensors such as the acoustic signal and NIR images.
