ADDITIVE MANUFACTURING OF AN INORGANIC GEOPOLYMER OBJECT
The present patent disclosure concerns a method for producing an object by additive manufacturing, the method comprising at least one repetition of the steps; providing a layer of particulate material on a surface; wherein the particulate material comprises: 15 to 70 wt% of an aluminosilicate oxide based compound having a Si:Al molar ratio in the range of 0.7 to 2.5, the aluminosilicate oxide based compound being an anhydrous pozzolanic aluminosilicate compound, and an inorganic aggregate; compacting the layer of particulate material provided on the production surface; providing a liquid composition on the compacted layer of particulate material, wherein the liquid composition is an aqueous solution comprising 10 to 50 wt% alkali metal silicate having a molar ratio of Si:M in the range of 0.7 to 1.5, wherein M is an alkali metal; and forming the object by allowing the liquid composition to react with the particulate material.
