Abstract: A method for producing a three-dimensional object from a curable binder composition with an additive manufacturing process includes producing the curable binder composition in the setting state, preferably by mixing constituents of the curable binder composition in a mixing unit, conveying the curable binder composition in the setting state via a supply line to a printing head movable in at least one direction, applying the curable binder composition in the setting state with the printing head, preferably layer-by-layer, to form the three-dimensional object, determining a temperature of the curable binder composition in the mixing unit, in the supply line and/or in the printing head, adjusting the temperature of the curable binder composition in the mixing unit and/or in the supply line and/or adjusting the temperature of at least one of the constituents of the curable binder composition before adding it into the mixing unit.

Abstract: A method for the application of hydrous mineral binder compositions which contain fibres. An aqueous accelerator is mixed with the aqueous binder composition in a mixer shortly before the application. The method is very robust and makes it possible to quickly produce even large moulded bodies having a uniform surface and very good strength development properties.
