The invention relates to the technical field of 3D printing, in particular to a guide type forming method of 3D printed ceramic. The method is characterized by comprising the steps as follows: (1) a modified ceramic precursor and photosensitive resin are mixed uniformly to form ceramic slurry; (2) the ceramic slurry is added to a photocuring forming device for 3D printing, layer-by-layer printingis performed according to a three-dimensional ceramic model by use of controllable ultraviolet light beams in a surface exposure or point scanning manner, and a modified ceramic precursor biscuit is formed; (3) the modified ceramic precursor biscuit is subjected to pyrolysis treatment in the required atmosphere to be converted into ceramic. Guided forming of different target ceramic components isrealized by changing different modified ceramic precursors or different calcination atmospheres and temperatures of the same ceramic biscuit, the method has target guide property and high controllability, and the prepared cera
