Abstract

See full text

Methods of additive manufacturing using noble metals and/or copper metal, and binder compositions for use during the additive manufacturing methods, are generally described. In some instances, the methods of additive manufacturing include de-binding (and in some cases sintering steps) that afford metal-based composites, de-bound metal structures, and metal objects containing noble metals (e.g., silver, gold, platinum) and/or copper that have improved properties, such as relatively high densities. In certain aspects, combinations of certain metal powders (e.g., noble metal and/or copper powders) with certain binder compositions may result in improved properties of resulting metal objects produced by the additive manufacturing process, such as relatively low surface roughnesses. The binder compositions described may include a low molecular weight polymer (e.g., including an acrylic acid repeat unit) and, in some cases, a cross-linking agent.
