Abstract
Official abstract text for this publication.
Provide is a cement ink for a cement ink for 3D printing (which also includes additive manufacturing) of 3D cement structures and materials. The cement ink includes an American Petroleum Institute (API) Class G cement, a nano-clay, a superplasticizer, a hydroxyethyl cellulose, and a defoamer. The nano-clay may be hydrophilic bentonite. The superplasticizer may be a polycarboxylate ether. The defoamer may be 2-ethyl-1-hexanol. Processes for forming the cement ink and printing 3D cement structures using the cement ink are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A printable cement composition, comprising: American Petroleum Institute (API) Class G cement; hydrophilic bentonite; a polycarboxylate ether, hydroxyethyl cellulose; and 2-ethyl-1-hexanol. 2. The printable cement composition of claim 1 , comprising water. 3. A printable cement composition, comprising: a cement; a nano-clay; a superplasticizer; hydroxyethyl cellulose; and a defoamer. 4. The printable cement composition of claim 3 , wherein the cement comprises American Petroleum Institute (API) Class G cement. 5. The printable cement composition of claim 3 , wherein the nano-clay comprises hydrophilic bentonite. 6. The printable cement composition of claim 3 , wherein the superplasticizer comprises a polycarboxylate ether. 7. The printable cement composition of claim 3 , wherein the defoamer comprises 2-ethyl-1-hexanol. 8. The printable cement composition of claim 3 , comprising water. 9. A method for creating a 3D structure, comprising: printing, using a 3D printer, one or more layers of the 3D structure using a printable cement composition, the printable cement composition comprising: American Petroleum Institute (API) Class G cement; hydrophilic bentonite; a polycarboxylate ether, hydroxyethyl cellulose; and 2-ethyl-1-hexanol. 10. The method of claim 9 , wherein the 3D structure is a honeycomb structure. 11. The method of claim 9 , wherein the 3D structure is a tubulane. 12. The method of claim 9 , wherein the 3D printer comprise a direct ink writing (DIW) printer. 13. The method of claim 9 , wherein the printable cement composition comprises water. 14. A method for creating a 3D structure, comprising: printing, using a 3D printer, one or more layers of the 3D structure using a printable cement composition, the printable cement composition comprising: a cement; a nano-clay; a superplasticizer; hydroxyethyl cellulose; and a defoamer. 15. The method of claim 14 , wherein the cement comprises American Petroleum Institute (API) Class G cement. 16. The method of claim 14 , wherein the nano-clay comprises hydrophilic bentonite. 17. The method of claim 14 , wherein the superplasticizer comprises a polycarboxylate ether. 18. The method of claim 14 , wherein the defoamer comprises 2-ethyl-1-hexanol. 19. The method of claim 14 , wherein the 3D structure is a honeycomb structure. 20. The method of claim 14 , wherein the 3D structure is a tubulane. 21. The method of claim 14 , wherein the 3D printer comprise a direct ink writing (DIW) printer. 22. The method of claim 14 , wherein the printable cement composition comprises water.
