3D PRINTING INTO A LIQUID MEDIUM

Abstract:

A three-dimensional printer includes a vessel containing a liquid in which a printed object can debind during fabrication. More generally, the vessel may contain any liquid medium selected to control or modify properties of a printed object during fabrication. For example, the liquid may also or instead impose a controlled thermal environment for the printed object, apply finishing materials to an exterior surface of the object, provide a component or catalyst for a reaction, or otherwise treat the printed object or control ambient conditions during printing.
