Online rheology determination in additive manufacturing processes

Abstract

A method for producing a three-dimensional object from a curable binder composition with an additive manufacturing process, the method including the steps of: producing the curable binder composition in the setting state, preferably by mixing the 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 spatial direction, applying the curable binder composition in the setting state by means of the printing head, wherein the curable binder composition is preferably applied layer-by-layer, to form the three-dimensional object, determining a pressure drop over a length section of the supply line with at least two pressure measuring device(s), optionally, determining a flow rate of the curable binder composition in the supply line, optionally determining a temperature of the curable binder composition in the supply line.
