Abstract
Provided herein are compositions, methods, and systems related to 3D printing a reactive vaterite cement composition, comprising feeding a composition comprising reactive vaterite cement through a 3D printing machine; printing a 3D printed reactive vaterite cement product; and curing the 3D printed reactive vaterite cement product by transforming reactive vaterite cement in the 3D printed reactive vaterite cement product to aragonite and/or calcite during and/or after the curing.
Claims20
A method, comprising:
- (i) feeding a thixotropic composition comprising reactive vaterite cement through a 3D printing machine;
- (ii) printing a 3D printed reactive vaterite cement product;
- and
- (iii) curing the 3D printed reactive vaterite cement product and transforming the reactive vaterite cement in the 3D printed reactive vaterite cement product to aragonite and/or calcite during and/or after the curing,
- wherein during the feeding, the printing, and/or the curing, providing one or more of pressure, heat, and/or humidity to make the composition comprising reactive vaterite cement flow, to prevent transformation of the reactive vaterite cement, and/or to increase rate of the transformation.

A 3D printing machine system to form a 3D printed cement product, comprising:
- (i) a feed system configured to feed a composition comprising reactive vaterite cement to printing head of a 3D printing machine;
- (ii) the 3D printing machine operably connected to the feed system and configured to accept the composition comprising reactive vaterite cement and print a 3D printed reactive vaterite cement product;
- and
- (iii) a vibrator system operably connected to the feed system and/or the 3D printing machine and configured to vibrate the feed system and/or one or more components of the 3D printing machine to provide mixing of the composition comprising reactive vaterite cement and/or make it flowable.
