This technique can be broken down into four categories of operations: encasement, setup, forming, and extraction. All operations involve a forming medium, and a workpiece. The workpiece can be composed of any material so long as the forming medium is temperature, viscosity, and chemically compatible. The vitreous forming medium translates outside forces into the workpiece to create various geometries. This forming medium can remain a part of the final assembly or get extracted after forming takes place. Workpiece geometry is affected by forming tool geometry, initial setup, heat, and material properties. This process can be used as a fast, efficient means of forming metal or other materials with unique abilities to control material combinations, surface chemistry, texture, and overall geometry. | 2021-08-19 |
