Abstract
A method for solid free-form fabrication of a three-dimensional object includes depositing a particulate blend in a defined region, the particulate blend including radical source particulates, polyacid particulates, multivalent cation particulates, and a calcium phosphate source particulates, ink-jetting a liquid phase binder onto a predetermined area of the particulate blend to form hydrated cement in the predetermined area, wherein the liquid phase binder is acidic and includes reactive monomers, and hardening the hydrated cement.
Claims51
A method for solid free-form fabrication of a three-dimensional object, comprising:
- depositing a particulate blend in a defined region, said particulate blend including radical source particulates, polyacid particulates, multivalent cation particulates, and calcium phosphate source particulates;
- ink-jetting a liquid phase binder onto a predetermined area of said particulate blend to form hydrated cement in said predetermined area, wherein said liquid phase binder is acidic and includes reactive monomers;
- and
- setting said hydrated cement.
A system for solid freeform fabrication of three-dimensional objects comprising:
- a particulate blend including polyacid particulates, multivalent cation particulates, and calcium phosphate source particulates;
- a radical forming source;
- and
- an acidic ink-jettable aqueous binder including reactive monomers and multifunctional monomers, wherein said ink-jettable aqueous binder is configured to hydrate said particulate blend to form a cement.
The system of clam 19, wherein said radical forming source is disposed in said aqueous binder.
A solid three-dimensional prototype composition, comprising:
- multiple layers of cement deposited in contact with one another, each of said multiple layers of cement comprising a particulate blend including radical source particulates, polyacid particulates, multivalent cation particulates, and calcium phosphate source particulates;
- wherein said particulate blend was hydrated and hardened by use of an ink-jettable aqueous binder.
