Abstract

The invention relates to the field of ceramic manufacturing, in particular to a method of ceramic 3D printing forming through temperature induced curing and application of the method. The method comprises the steps of paste preparation, 3D printing and induced curing, wherein during paste preparation, on the basis of the weight of ceramic powder, 1-4% of carrageenin powder is mixed; and during induced curing, printed paste is placed in an environment at 60-70 DEG C. The purpose of rapid curing can be achieved under the situation of ensuring the continuity and precise forming capability of thepaste, and a printed body is free of obvious defects and obvious deformation. The method is simple, efficient and easy to implement, and application and popularization of the 3D printing technology inthe ceramic field are facilitated.
