Abstract (en)
[origin: WO2021121487A1] The invention relates to: a method for the layered construction of bodies comprising refractory moulding base material and resol resins as binders, having, in addition to phenol, ortho- and/or para-substituted phenols as monomer structural elements; three-dimensional bodies manufactured using this method; and a binder for three-dimensionally constructing bodies, in particular moulds and cores for metal casting.
