Abstract: The present invention is a novel method for freeform fabrication. Specifically, the method of solid freeform fabrication has the steps of:(a) preparing a slurry by mixing powder particles with a suspension medium and a gelling polysaccharide;(b) making a layer by depositing an amount of said powder slurry in a confined region;(c) hardening a selected portion of the layer by applying a gelling agent to the selected portion; and(d) repeating steps (b) and (c) to make successive layers and forming a layered object. In many applications, it is desirable to remove unhardened material followed by heating to remove gellable polysaccharide then sintering.

Abstract: A method for producing a highly loaded, aqueous suspension having a pourable viscosity and containing from 20 to 50 volume percent colloidal ceramic or metal particles. A biologically produced polymer dispersant having a high density of carboxyl functional groups and an average molecular weight of at least 1,000 is solubilized in water in a quantity of less than 1.0 percent dry weight basis of particles. The ceramic or metal particles are then introduced to the solution, and agitated to form a substantially nonagglomerated suspension. The polymer dispersant may be produced by a bacterium grown in situ with the particles. A biologically produced polymer gelling agent that is miscible with the polymer dispersant may be admixed into the suspension, which is then maintained in a nongelled state while being supplied to a mold. The suspension is then exposed to a gel-triggering condition to form a gelled, sinterable article.
