A method for the layered construction of models is disclosed, whereby at least one first material is applied to a building platform and then a second material is selectively applied in layers. Both application steps are then repeated until the desired model is obtained and the both materials form a solid body with a desired mixing ratio. The first material comprises a moulding sand and the first and/or the second material comprises a binder, comprising a crystalline salt binder, or/and a protein binder. |
