Abstract

The present invention provides a method of additive manufacturing a 3D-printed article, comprising: (a) printing and depositing one or more layers of a slurry by using a 3D printer, wherein the slurry comprises a ceramic powder composition; (b) further injecting an oil around the one or more layers of slurry, wherein the height of the injected oil is lower than the height of the slurry; (c) repeating steps (a) and (b) until a main body with desired geometric shape is obtained; and (d) sintering the main body by heating to obtain the 3D-printed article wherein the temperature of a printing carrier of the 3D printer is from 30 to 80° C.
