摘要
A binder solution comprises greater than or equal to 0.5 wt % and less than or equal to 20 wt % of nanoparticles, a thermoplastic binder, and a solvent. The nanoparticles may comprise metallic nanoparticles comprising nickel, silver, chromium, aluminum, cobalt, iron, or combinations thereof. The nanoparticles may comprise ceramic nanoparticles, the comprising alumina, aluminum nitride, zirconia, titania, silica, silicon nitride, silicon carbide, boron nitride, or combinations thereof. A method of manufacturing a part includes depositing a layer of particulate material on a working surface, applying a binder solution into the layer of particulate material in a pattern, repeating the steps of depositing and selectively applying to form a plurality of layers of particulate material with the applied binder solution, and curing the applied binder solution in the plurality of layers of particulate material with the applied binder solution to evaporate the solvent and thereby form a green body part.
