  • Process and apparatus for the free-forming manufacture of three dimensional components of predetermined shape
    Patent number: 5649277
    Abstract: An apparatus and process for the free-forming manufacture of three-dimensal components. A powder-binder mixture, or a material with a high melting point, is plasticized or made molten, by raising the temperature inside a process chamber. The resulting molten material is discharged under pressure through a nozzle which is arranged at the end of the process chamber. The material inside the process chamber is deposited in layers. The processing direction and processing speed of the nozzle are programmed. An embodiment of the invention is disclosed in which a non-molten powder is deposited and supported by the deposition of a second powder alongside the non-molten powder.
