The invention pertains to the use of sophisticated chemical formulation and spectroscopic design methods to select taggants compatible with the 3D print medium that are easily detected spectroscopically but otherwise compatible with the product, structural integrity and stability, and aesthetics. A spectral pattern employs a different chemical or combination of chemicals to alter the formulation of all or some portion of the printed object so that its authenticity can be monitored later using a spectrometer.

Use of 3D printing for anticounterfeiting

Multisource fusion of data is used on a handheld device to create a portable analytical verifier, including the ability to verify based on product wrapping or using a re-turned code to check the product or wrapping. Data words are extracted from authentication media by testing to see whether particular taggants are present, using spectroscopic analysis.
