▎ 摘　　要

NOVELTY - Producing (m1) an additive manufacturing feedstock (200) comprises adding a photothermal agent to a construction material to cause the photothermal agent to be in thermally conductive contact with the construction material to produce the additive manufacturing feedstock, where the photothermal agent comprises chemically modified graphene (CMG). USE - The method is useful for producing an additive manufacturing feedstock. ADVANTAGE - The method: allows system to operate with a wider range of feedstocks; improves enhanced photothermal and thermal conduction properties; reduces the oxygen content (oxygen and other oxygen functional groups e.g. hydroxide and carboxylic acid) of the GO to produce RGO; and is economical. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an additive manufacturing feedstock comprising a construction material, and a photothermal agent to convert at least a part of incident light into thermal energy; (2) additive manufacturing (m2) comprising directing electromagnetic (EM) radiation onto an additive manufacturing feedstock, thus fusing portions of the additive manufacturing feedstock to form a component, where the additive manufacturing feedstock comprises a construction material and a photothermal agent to convert at least a portion of the light into thermal energy; and (3) a photothermal agent for enhancing photothermal properties of an additive manufacturing feedstock, comprising CMG. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view for manufacturing an additive manufacturing feedstock. Additive manufacturing feedstock (200) Flakes (202) Powder (204)
