    摘要: A solid freeform fabrication system includes a powdered build material deposited as a layer in a fabrication bin; a binding powder deposited as a layer over the layer of powdered build material; and an activating fluid that is selectively dispensed from an ejection head to activate the binding powder. The activated binding powder then selectively binds the build material into a cross-section of an object being fabricated.

    摘要: A method for solid free-form fabrication of a three-dimensional metal object includes depositing a particulate blend in a defined region, the particulate blend including a number of metal or metal alloy particulates and a peroxide, and selectively ink-jetting a binder system onto a predetermined area of the particulate blend to form a green part, wherein the liquid phase binder includes a water soluble monofunctional acrylate-based monomer, a water soluble difunctional acrylate-based monomer, an amine, and water.

    摘要: 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.
