Abstract: The present disclosure provides methods for generating three-dimensional (3D) objects. The methods may comprise generating a green part corresponding to the 3D object. The green part may comprise a plurality of particles and reactants for conducting a self-propagating reaction. The reactants may be used to conduct a self-propagating reaction that generates heat sufficient to de-bind or pre-sinter the green part. External heat may be supplied to the green part to sinter the plurality of particles, thereby yielding the 3D object. The disclosure also provides methods for generating a 3D object using a resin. The methods may comprise using the resin to generate a green part, heating the green part at a first temperature to decompose a binder in the green part, heating the green part at a second temperature to decompose a polymeric material in the green part, and sintering the green part to yield the 3D object.

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.
