Abstract
A method is described here for the layerwise construction of models, wherein, in a building region, a particulate material is applied layerwise and selectively cured. These steps are repeated until a desired model is obtained. The material comprises in this case a particulate building material and a spray-dried alkali metal silicate solution. Selective activation of the curing proceeds using a water-comprising solution.
Claims20
A method for building models in layers, wherein a particulate material is applied in layers in a build space and selectively hardened and these steps are repeated until a desired model is obtained, the material comprises a particulate building material, characterized in that the material comprises a spray-dried alkali silicate solution, curing that is selectively activated by a solution containing water, and that a drying process is involved.
A material system for building models in layers, wherein a particulate material is applied in layers in a build space and selectively hardened and these steps are repeated until a desired model is obtained, the material comprises a particulate building material, characterized in that the material further comprises a spray-dried alkali silicate solution, and that a polar solvent, in particular a solution containing water, is used for selectively activating the hardening.
