Abstract
An article produced using, among other techniques, free-form fabrication having a binder matrix and particles can be supported during a temperature processing, such as burn-out of the binder matrix, with a support composition to maintain geometry and/or alleviate changes in geometry of the article. The support composition can take a variety of forms such as foams, two phase materials, plastic powders, carbon powders, etc. The support material is sacrificed during the thermal processing, such as through decomposition. Such a decomposition can occur when the support composition evolves into a carbonaceous structure. The support composition can also oxidize to a gas, melt, or vaporize, among other types of sacrificial action.
