Beschreibung
Zusammenfassung:	The present invention relates to methods for the layered construction of molds and cores that include refractory molding base material, a hydrophobized metal oxide as solids and a binder containing at least water glass in the form of an aqueous alkali silicate solution. The methods involve applying a refractory molding base material in layers and selectively print the molds and cores using the binder. The present invention further relates to molds or cores produced in accordance with these methods.
