One of the most important aspects to consider when choosing a 3D printer is the type of extruder it will use, direct extrusion or Bowden.<\/p>\n\n\n\n

In this article, I want to explore the differences between the two options and which one is best for your 3D printer.<\/p>\n\n\n\n

What is direct extrusion<\/h2>\n\n\n\n

Direct extrusion is an extrusion system that is mounted directly on the print head<\/strong> (Hotend). The filament is fed directly from the extruder to the print head, where it is melted and deposited on the build platform layer by layer. <\/p>\n\n\n

This type of extruder is commonly used in high-end desktop 3D printers and high-end 3D printers.<\/p>\n\n\n\n

Advantages of direct extrusion<\/h3>\n\n\n\n
    \n
  • Mismatches or mismatches are avoided in the pneumatic connectors.<\/li>\n\n\n\n
  • Ability to print flexible and abrasive materials.<\/li>\n\n\n\n
  • Easier to change filament<\/li>\n<\/ul>\n\n\n\n

    Disadvantages of direct extrusion<\/h3>\n\n\n\n
      \n
    • Increased weight on the print head, which can decrease print speed<\/li>\n\n\n\n
    • Higher cost (of 3D printers) compared to Bowden extruders.<\/li>\n<\/ul>\n\n\n\n

      What is the bowden extruder<\/h2>\n\n\n\n

      The Bowden extruder is characterized by having the motor and the extruder separated from the print head. The filament is fed from the extruder through a Teflon tube and deposited in the print head. <\/strong><\/p>\n\n\n

      This type of extruder is commonly used in low-cost desktop 3D printers and mid-range 3D printers.<\/p>\n\n\n\n

      Bowden Extruder Advantages<\/h3>\n\n\n\n
        \n
      • Less weight on the print head, which increases print speed.<\/li>\n\n\n\n
      • Lower cost compared to direct extrusion 3D printers.<\/li>\n<\/ul>\n\n\n\n

        Bowden Extruder Disadvantages<\/h3>\n\n\n\n
          \n
        • Limitations in printing flexible and abrasive materials.<\/li>\n\n\n\n
        • Difficult to change the filament.<\/li>\n\n\n\n
        • Possible errors when loosening the bowden tubes from the couplings.<\/li>\n<\/ul>\n\n\n\n

          Which system is best for your 3D printer?<\/h2>\n\n\n\n

          If you are looking for greater precision in printing and the ability to print flexible and abrasive materials, direct extrusion is the best option.<\/strong> <\/p>\n\n\n\n

          Direct extrusion comes factory installed for high-end, high-end desktop 3D printers<\/strong> (although there are exceptions), while the Bowden extruder is already installed by default in low-cost and mid-range 3D printers.<\/p>\n\n\n\n

          The fact that this extrusion system has some advantages does not mean that the quality of 3D prints will be bad with a Bowden system. Still the advantages of a direct extruder are considerable<\/strong>.<\/p>\n\n\n\n

          If what you want is to upgrade your bowden system printer to a direct extrusion system then you should analyze which one is compatible with your 3D printer<\/strong>.<\/p>\n\n\n\n

          Typically when purchasing a direct extruder for an Ender 3, you will need to include a new spool with the motor already mounted, ready to go.<\/p>\n\n\n\n

          Change Ender 3 to direct extrusion<\/h2>\n\n\n\n

          If you cannot or do not want to buy a direct extrusion system for your Ender 3, what you can do is try a Thingiverse design that allows you to do this adaptation with the same extruder motor.<\/p>\n\n\n

          I recommend printing it in Petg for longer life and getting the extension cords.<\/p>\n\n\n\n
