A rapid-prototyping production method for producing a structural body by deposition, in several subsequent deposition steps, of subsequent layers of a building material one onto the other. The building material is selectively deposited in each layer in a liquid state in the form of droplets and being caused to solidify when deposited. After deposition, the layer is lowered into a supporting fluid which has a liquid state and has a density which is at least the same as the density of the building material.

Cette invention concerne un procédé de réalisation rapide d'un prototype. Ce procédé permet d'obtenir un corps structural par dépôt, en plusieurs opérations successives, de couches de matériau successives les unes sur les autres. Dans chaque couche, le matériau de construction est déposé sélectivement en phase liquide sous forme de gouttelettes et se solidifie au moment où ils se dépose. Après dépôt, la couche est abaissée dans un fluide support à l'état liquide dont la densité est au moins égale à celle du matériau de construction.
