Abstract
The invention relates to the making, on a support plate (34), of an annular space (76) in a ceramic paste covering this plate, in order, by successive deposits and firing of layers of said ceramic paste, to create a base of a ceramic shell (40) for the moulding of parts, the base having said annular space (76). For this purpose, between two deposits of said ceramic paste, and on the plate, said deformable annular element (82) will be deformed in order to break the ceramic layer.
