This study introduces a terahertz (THz) wave method for nondestructive identification of 3D-printed objects by embedding 1D barcodes within their design files. This technique enables efficient and practical authentication of 3D-printed items.

Area of Science:

  • Additive Manufacturing
  • Non-destructive Testing
  • Terahertz Spectroscopy

Background:

  • The increasing use of 3D printing across various industries necessitates robust methods for identifying and authenticating printed objects.
  • Current identification methods may be destructive or insufficient for complex internal structures.
  • There is a need for non-destructive techniques to verify the integrity and origin of 3D-printed components.

Purpose of the Study:

  • To develop and demonstrate an all-in-one encoder/decoder system for the non-destructive identification of 3D-printed objects.
  • To integrate a 1D identification code directly into the 3D model's stereolithography (STL) file.
  • To utilize terahertz (THz) waves for extracting embedded identification codes without damaging the object.
