Abstract
An ink for three dimensional printing a ceramic material includes metal oxide nanoparticles and a polymer resin, where a concentration of the metal oxide nanoparticles is at least about 50 wt % of a total mass of the ink. A method of forming a porous ceramic material includes obtaining an ink, where the ink comprises a mixture of metal oxide nanoparticles and a polymer, forming a body from the ink, curing the formed body, heating the formed body for removing the polymer and for forming a porous ceramic material from the metal oxide nanoparticles. The forming the body includes an additive manufacturing process with the ink.
