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.

Support for a fired article

In addition to working curves, other equally important, but previously not understood, relationships exist for both the green strength and the cured line width of ceramic-loaded resins. These characteristics of cured parts are strongly affected by the dose rate, a parameter usually controlled with laser power. Multiple smaller doses are used to produce a total integrated dose. Multiple exposures benefit from using high power to produce a fast process. However, since the dose for a given layer is broken into several smaller doses, the negative effect of high power on strength and cured linewidth is reduced.

Embodiments of the present invention include methods and systems for leaching material from an object. Examples include leaching ceramic from metallic components. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for leaching systems. Further embodiments, forms, features, aspects, benefits, and advantages of the present application shall become apparent from the description and figures provided herewith.

Systems and methods for leaching a material from an object

A manufacturing method for producing ceramic item from a photocurable ceramic filled material by stereolithography. The method compensates for the anisotropic shrinkage of the item during firing to produce a dimensionally accurate item.

Method and apparatus associated with anisotropic shrink in sintered ceramic items

The removal of ceramic material from the interior of cast metallic components is accomplished in a closed system. A vessel within the system is filled with a chemical leaching fluid that immerses the cast component having the ceramic material and/or ceramic cores therein. The leaching fluid is superheated and boiling is controlled by varying the pressure within the closed system without changing the molecules in the vessel.
