    Abstract: A composition can comprise particles comprising 5% by weight (wt %) or more, a photo-initiator, a curing agent, a dispersant, and an organic binder. The composition can be substantially solvent-free. In some embodiments, particles comprise 65 wt % or more. In some embodiments, the curing agent comprises dipropylene-glycol diacrylate. In some embodiments, the dispersant comprises a phosphate ester. In some embodiments, the organic binder comprises isobornyl methacrylate. In some embodiments, the composition comprises a viscosity from about 100 milliPascal-seconds to about 7,000 milliPascal-seconds. Methods of making a green body can comprise creating a composition, printing the green body using the composition, and curing the green body. Method of making a printed article can comprise creating a composition, printing a green body using the composition, curing the green body, heating the green body to remove the organic binder to form a porous article, and sintering the porous article to form the printed article.
