Abstract
A method of manufacturing molds and cores suitable for producing fiber composite bodies or cast parts of metal or plastic from a mold base material and a multicomponent binder by 3D printing includes pretreating the particulate mold base material with at least one silicon-organic compound having a polar hydrophilic end and a nonpolar hydrophobic end, forming a layer of the pretreated particulate mold base material, and applying the binder or at least one component of the binder in liquid form to the layer, wherein b. and c. are repeated.
