1. A method for manufacturing an integrally formed bladed disk of a turbomachine, said method comprising:
manufacturing a plurality of blades, the blades comprising a root and a profiled portion;
placing the blades in a first annular spark plasma sintering mold which comprises a first metal powder, the blades being angularly distributed over a contour of the first annular spark plasma sintering mold, the root of the blades being embedded into the first metal powder, the profiled portion of the blades protruding from the first metal powder radially outwardly;
spark plasma sintering the blades with the first metal powder so as to form an intermediate disk;
placing the intermediate disk in a second spark plasma sintering mold which comprises a second metal powder;
spark plasma sintering the intermediate disk with the second metal powder,
the blades being monocrystalline before and after the spark plasma sinterings with the first and second metal powders.
