Generative processes for production of a three dimensional object comprised of particles are increasingly employed in the manufacture of casting molds and casting cores. Therein the casting mold is constituted of sand particles, which are joined using a binder material. The task of the present invention is comprised therein, of providing an alternative layer building-up process for production of a three dimensional object, which achieves sufficient casting stability, without suffering intolerable quality degradation due to evolution of off-gases from binder material during casting. This task is solved by a process employing particles, which are comprised of a mono- or polyvalent, water and/or alcohol soluble metals salt.
