Abstract: A matrix material dispersed with one or more susceptor structures can be formed into a feedstock for an additive manufacturing process. The one or more susceptor structures can be excited by an energy field such as an electric field, a magnetic field, an electromagnetic field, or any combination thereof, to produce heat. The heat that is produced can be transferred to the matrix material that surrounds the one or more susceptor structures to provide heat treatment to the matrix material. The heat treatment can improve the material and mechanical properties of three dimensional objects formed from the feedstock.

The polymers degrade upon two-photon excitation, which allows for easy decomposition of polymeric products made therefrom. The decomposition can occur when the polymer is exposed to light of intensities sufficient to induce the two-photon excitation, which in turn cleaves the polymer at one or more sites where the chromophores are attached.
