Tungsten carbide-cobalt by Three Dimensional Printing
Three Dimensional Printing is an additive manufacturing process for rapid prototyping ceramic and metallic parts [Sachs, et al, 1990]. Green (not sintered) tungsten carbide-cobalt parts must have a density greater than 50% of the theoretical density, 14.9 g/cc, for proper sintering and …

Vector drop-on-demand production of tungsten carbide-cobalt tooling inserts by three dimensional printing
Three Dimensional Printing (3DP) is a solid freeform fabrication process used to generate solid parts directly from three-dimensional computer models. A part geometry is created by selectively depositing binder into sequentially spread layers of powder. In slurry-based 3DP, a suspension of powder …

Bimetallic bars with local control of composition by three-dimensional printing
Three Dimensional Printing (3DP) is a process that enables the fabrication of geometrically complex parts directly from computer-aided design (CAD) models. The success of 3DP as an alternative manufacturing technology to bulk machining of materials for complex parts has been demonstrated. By proof …

Development of an advanced materials system for tooling produced by three-dimensional printing
Three Dimensional Printing (3DP™) is a manufacturing technique in which a powdered material is used to build parts with complicated geometries directly from a three dimensional computer model. This technique has been used in the past to manufacture metal parts with complicated geometries. The three …

Infiltration stop, epoxy tooling development, and shrinkage studies in three dimensional printing
Three Dimensional Printing (3DP) is an advanced rapid prototyping process which can not only fabricate prototypes but functional tooling as well. In the process, a thin layer of powder is spread onto a powder bed to which a printhead delivers the binder that selectively joins the particles. …
