Abstract: Components build up of layers can be produced by means of the so-called three dimensional printing process from plaster or cement powder. It is the task of the present invention to provide another component build up in layers and a process for production thereof, which component exhibits at least comparable strength and at most the same manufacturing cost. The task is solved thereby, that the component is a reaction product of a particulate material and an aqueous liquid, wherein the component includes a number of layers of the reaction product, and wherein the particulate material contains plaster-free cement.
