Abstract (en)
[origin: WO2021209423A1] The invention relates to a method for building up layer by layer cured three-dimensionally layered shaped bodies for foundry cores and moulds from a refractory moulding base material (1) with an average grain size ranging from 0.1 mm to 2.0 mm and to the use of an inorganic binder (3) containing an alkali-silicate solution for producing cured three-dimensionally layered shaped bodies for foundry cores and moulds.
