FIELD: material engineering. n SUBSTANCE: group of inventions relates to a method for layer-by-layer formation of cured three-dimensional molded products, as well as to a shape or rod obtained by this method. The claimed method is carried out by means of layer-by-layer formation using a resinous component that contains at least furan resin and more than 5 wt. %, and less than 50 wt. %, monomeric furfuryl alcohol, and acid. Molded products obtained this way are suitable, among other things, as molds and rods of molds for casting metal. n EFFECT: group of inventions provides a reduction in the time to receive products. n 25 cl, 1 tbl, 1 ex |
