Using of Aerosint’s multi-material selective powder deposition technology to enable covert chemical “tagging” of AM parts produced by LPBF


Aerosint’s invented an alternative powder re-recoating system that, instead of uniformly spreading just one single powder material, selectively deposits two (or more) powders to form a single layer containing two materials.


The challenge:

  • Print authentication tag inside powder based AM parts which could be identified with Infratrac’s solution (requires multi-material process).
  • Tagged parts do not differ mechanically or functionally from non-tagged parts.
  • Tagged parts can be readily detected with spectroscopy methods.
