Abstract
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.

Apparatus for additive manufacturing with respect to a work piece, the apparatus comprising:
- a feed stock area holding feed stock for the additive manufacturing;
- means passing a portion of the feed stock to the work piece;
- whereby the portion of the feed stock passed to the work piece is joined thereto;
- the apparatus further comprising a spectroscopic means at the feed stock area;
- the apparatus further comprising enforcement means responsive to information from the spectroscopic means, the enforcement means carrying out a human-perceptible annunciation depending upon spectroscopic characteristics of feed stock held in the feed stock area.
Apparatus comprising:
- a scanner scanning a three-dimensional object to generate a data file indicative of the three-dimensional shape thereof;
- said scanner further disposed to read an indicium on the three-dimensional object if present;
- said scanner further disposed to respond to presence of the indicium to annunciate such presence to a human user.
A method for use with a scanner scanning a three-dimensional object to generate a data file indicative of the three-dimensional shape thereof, said scanner further disposed to read an indicium on the three-dimensional object if present, the method comprising the steps of:
- scanning a three-dimensional object;
- and
- responding to presence of an indicium to annunciate such presence to a human user.
A method for use with a 3D scanner, the method comprising:
- placing a work piece into the scanner;
- commencing a 3D scan by means of the 3D scanner of the work piece;
- carrying out a spectroscopic analysis of the work piece in the scanner, yielding spectroscopic data;
- in the event of the spectroscopic data being indicative of a first conclusion about the work piece, then finishing the 3D scan and providing results of the 3D scan to a human user;
- in the event of the spectroscopic data being indicative of a second conclusion about the work piece, then annunciating the second conclusion to a human user.
