CEMENT-BASED DIRECT INK FOR 3D PRINTING OF COMPLEX ARCHITECTED STRUCTURES
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 hydroxy ethyl cellulose, and a defoamer. The nano-clay may be hydrophilic bentonite. The superplasticizer may be a polycarboxylate ether. The defoamer may be 2-ethyl- l-hexanol. Processes for forming the cement ink and printing 3D cement structures using the cement ink are also provided.
L'invention concerne une encre à base de ciment destinée à une encre à base de ciment pour l'impression 3D (qui concerne également la fabrication additive) de structures et de matériaux de ciment 3D. L'encre à base de ciment comprend un ciment de classe G de l'American Petroleum Institute (API), une nano-argile, un superplastifiant, une hydroxyéthyl cellulose, et un agent antimousse. La nano-argile peut être une bentonite hydrophile. Le superplastifiant peut être un éther de polycarboxylate. L'agent antimousse peut être le 2-éthyl-l-hexanol. L'invention concerne également des procédés de formation de l'encre à base de ciment et d'impression de structures de ciment 3D à l'aide de l'encre à base de ciment.
