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