A method for preparing a biological medical porous implant material comprises: uniformly mixing pure tantalum powder and a binding agent to obtain tantalum powder slurry placing in a steel die a high polymer resin template support which has the porosity of 20% to 50% and of which pores are completely connected in a three-dimensional way pouring the prepared tantalum powder slurry into the steel die until the high polymer resin template support is immersed slowly and uniformly applying pressure to the periphery of the steel die to ensure that the tantalum powder is fully and completely filled into the high polymer resin template support, the applied pressure being increased from 0 Mpa to 10 Mpa at a constant speed, and the time required by the pressure application process being 2 to 5 hours performing chemical dissolution to remove the high polymer resin template support to obtain a green body framework of porous tantalum and performing posttreatment such as degreasing and sintering to obtain the biological medical porous tantalum implant material. A product prepared by the method is a green body of the porous metal material of which pores are completely connected in the three-dimensional way, and the green body is sintered to form the porous metal implant material of which the pores are completely connected in the three-dimensional way, so that the porous metal implant material is high in biocompatibility.Un procédé de préparation dun matériau dimplant médical biologique poreux comprend les étapes consistant à : mélanger uniformément une poudre de tantale pur et un liant afin dobtenir une bouillie de poudre de tantale placer dans un moule en acier un support de gabarit en une résine de haut polymère dont la porosité est comprise entre 20 et 50 % et dont les pores sont entièrement reliés dune manière tridimensionnelle verser la bouillie de poudre de tantale préparée dans le moule en acier jusquà ce que le support de gabarit en une résine de haut polymère soit immer
