Zusammenfassung:	A method for manufacturing a three-dimensional object includes steps of: a) providing a digital description of the object as a set of voxels; b) sequentially creating an actual set of voxels corresponding to the digital set of voxels; wherein at least one voxel comprises a water-soluble poly urea derived from: i) a polymer or mixture of polymers and a composition ii) selected from the group consisting of: urea, diisocyanate (methylene diphenyl diisocyanate, toluene diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate) and mixtures thereof. Un procédé de fabrication d'un objet tridimensionnel comprend les étapes consistant à : a) fournir une description numérique de l'objet sous la forme d'un ensemble de voxels; b) créer séquentiellement un ensemble réel de voxels correspondant à l'ensemble numérique de voxels; au moins un voxel comprenant une polyurée hydrosoluble dérivée de : i) un polymère ou un mélange de polymères et une composition ii) choisie dans le groupe constitué par : l'urée, le diisocyanate (méthylène diphényl diisocyanate, toluène diisocyanate, hexaméthylène diisocyanate, isophorone diisocyanate) et leurs mélanges.
