PROCEDE DE FABRICATION DE PIECE DE FORME COMPLEXE PAR FRITTAGE SOUS PRESSION A PARTIR D'UNE PREFORME
This invention relates to a method for manufacturing a part of complex shape (3) by successive deposition of layers according to a technique of 3D additive printing and pressure sintering, comprising the following steps: an initial step of producing a model (1) from a material chosen from a porous or pulverulent material based on a metal alloy, a ceramic, a composite material and a lost material by formation of successive layers deposited according to the digitally controlled 3D additive printing technique, followed by a step of introducing a preform (1) made of porous or pulverulent material to be densified, derived from the model (1), into a mold (2) filled with a sacrificial porous or pulverulent material (13) in addition to the preform (1), the uniaxial densifying pressure sintering (10) then being applied to the mold (2) in order to form the part (3) which is finally extracted from the mold (2).
