The invention relates to a method for fast manufacturing specially-shaped ceramic prototype and specially-shaped ceramic. The method for fast manufacturing specially-shaped ceramic prototype comprises the following steps: providing a specially-shaped ceramic model, an inner model knife board and an outer inner model knife board, squeezing gypsum by the inner model knife board to form a terrace die, and scraping the intermediate gypsum by the outer inner model knife board and the terrace die positioned outside to form the specially-shaped ceramic prototype. The specially-shaped ceramic is manufactured by the method for fast manufacturing specially-shaped ceramic prototype. The method for fast manufacturing specially-shaped ceramic prototype provided in the invention can fast manufacture a specially-shaped ceramic prototype matching with the specially-shaped ceramic model with simplicity, convenience, fastness and low cost, which does not rely on any forming equipment and is suitable for designing and manufacturing various specially-shaped ceramics.
