## (57) ABSTRACT 

The invention relates to a method for producing three› dimensionally layered shaped bodies by means of layer-by› layer construction using a resin component which contains at least one furane resin, and more than 5% by weight and less than 50% by weight monomer furfuryl alcohol, and an acid. The shaped bodies produced in this manner are suitable inter alia as casting molds and casting cores for metal casting.
