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.

An endoprosthesis has an expanded state and a contracted state, the endoprosthesis includes a stent having an inner surface defining a lumen, having an outer surface, and defining a plurality of apertures through the outer surface, wherein the apertures are arranged in a micropattern; and a coating (e.g., polymeric coating) attached to the outer surface of the stent. The coating includes a base and a tissue engagement portion including a second surface facing outwardly from the stent, the tissue engagement portion including a structure that defines a plurality of holes extending inwardly from the second surface toward the base. The holes are arranged in a micropattern. When the endoprosthesis is expanded to the expanded state in a lumen defined by a vessel wall, the structure applies a force that may reduce stent migration by creating an interlock between the vessel wall and the endoprosthesis.
