FUSED FILAMENT FABRICATION PRINT HEAD SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240051223 titled 'FUSED FILAMENT FABRICATION PRINT HEAD SYSTEM

Simplified Explanation

The abstract of this patent application describes a fused filament fabrication print head system that includes a nozzle, a heating block, and a cooling element. The nozzle is used to deposit a filament through a nozzle opening, while the heating block is coupled to the nozzle and includes a heating element. The cooling element is spaced apart from the heating block and provides localized cooling to a portion of the filament prior to the heating block. This cooling preserves the stiffness of the filament and ensures sufficient back pressure to push the filament through the heating block and nozzle opening.

  • The patent application describes a print head system for fused filament fabrication.
  • The system includes a nozzle, a heating block, and a cooling element.
  • The nozzle is used to deposit a filament through a nozzle opening.
  • The heating block is coupled to the nozzle and has a heating element.
  • The cooling element is spaced apart from the heating block and provides localized cooling to a portion of the filament.
  • The cooling preserves the stiffness of the filament and maintains sufficient back pressure for filament flow.

Potential applications of this technology:

  • 3D printing: The described print head system can be used in 3D printers to deposit filaments and create three-dimensional objects.

Problems solved by this technology:

  • Filament stiffness preservation: The localized cooling provided by the cooling element ensures that the filament remains stiff, preventing deformation during the printing process.
  • Sufficient back pressure: The cooling element also helps maintain sufficient back pressure to push the filament through the heating block and nozzle opening, ensuring smooth and consistent filament flow.

Benefits of this technology:

  • Improved print quality: By preserving filament stiffness and ensuring sufficient back pressure, this technology can result in higher-quality 3D prints with reduced deformations.
  • Enhanced printing efficiency: The optimized filament flow facilitated by the cooling element can improve the overall efficiency of the printing process.


Original Abstract Submitted

various implementations include a fused filament fabrication print head system that includes a nozzle, a heating block, and a cooling element. the nozzle defines a nozzle opening and a filament flow path and is configured to deposit a filament through the nozzle opening. the heating block is coupled to the nozzle such that the filament flow path extends through the heating block. the heating block includes a heating element. the cooling element is spaced apart from the heating block along the filament flow path and is configured to provide localized cooling to a portion of the filament at a location along the filament flow path prior to the heating block. the localized cooling provided by the cooling element preserves the stiffness of the filament and ensures sufficient back pressure to push the filament through the heating block and nozzle opening.
