Compositions, methods of using the compositions, and solid freeform fabrication (SFF) systems for producing three-dimensional objects are disclosed. One exemplary composition, among others, includes a basic component, an acidic component, at least one monoacrylate component, a light sensitive initiator, and a polar binder. A polymerization reaction between the at least one monoacrylate component and the light sensitive initiator occurs upon exposure to optical energy. The polar binder includes a viscosity modifier and a surface tension modifier. The polar binder is capable of stimulating a crosslinking reaction between the basic component and the acidic component.

Solid freeform compositions, methods of application thereof, and systems for use thereof

Chemical compositions are disclosed. One exemplary composition, among others, includes: a basic component, an acidic component, at least one acrylate component, oxidizing agent, reducing agent, and a binder. The binder includes a viscosity modifier and a surface tension modifier. The binder is capable of stimulating a reaction between the basic component and the acidic component. A portion of the binder is capable of undergoing a polymerization reaction between at least one acrylate component, the oxidizing agent, and the reducing agent. The polymerization reaction being initiated by the redox reaction between the oxidizing agent and the reducing agent.

Compositions for solid freeform fabrication

An ink-jet ink composition and a method for printing are provided which involve the use of at least one perfluorinated solvent as part or all of the vehicle of the ink-jet ink. The ink-jet ink composition evidences improved bleed control, reduced paper cockle and curl, and reduced dry time upon printing onto a print medium. The use of perfluorinated solvents reduces or even eliminates material compatibility issues between the ink and the materials comprising the pen from which the ink is ejected.
