Abstract

The present invention describes a method for building models in layers, wherein a first material and subsequent thereto selectively a second material are applied in layers in a build space, and these two application steps are repeated until a desired model is obtained. The two materials form a solid object in a suitable mixing ratio, the first material including a particulate material and the second material being applied with the aid of a print head. The first material, the second material and/or the particulate material include one or more diamines and/or one or more dicarbonyl compounds as the binder.
