Abstract
A material for use in a 3D printer. The material may include a plurality of metallic particles and a stabilizing material. The metallic particles may have an average cross-sectional length that is less than or equal to about 100 nm. The stabilizing material may include an organoamine, carboxylic acid, thiol and derivatives thereof, xanthic acid, polyethylene glycols, polyvinylpyridine, polyninylpyrolidone, or a combination thereof.
