Nozzle Subsystem<\/h2>\n

Strengths and Weaknesses<\/h3>\n

The strengths of the nozzle subsystem include:<\/p>\n

    \n
  1. Consistent filament extrusion along preferred directions<\/li>\n
  2. Good temperature regulation (with insulation)<\/li>\n
  3. Modularity (Identical mounting interface as the original nozzle)<\/li>\n<\/ol>\n

    The weaknesses include:<\/p>\n

      \n
    1. Limited to convex parts that have 90\u00b0 or less with respect to the bed. That is a design limitation since our angle is fixed.<\/li>\n<\/ol>\n

      Rotary Joint Subsystem<\/h2>\n

      Strengths and Weaknesses<\/h3>\n

      Strengths:<\/strong><\/p>\n

      The main strengths of the rotary joint subsystem are:<\/p>\n

        \n
      1. High Repeatability – 3 times the stated requirement.<\/li>\n
      2. Small form factor – Light weight<\/li>\n
      3. Simplicity – Having a concentric hollow shaft stepper motor enables a simple implementation, when compared to rotary stage, or standard stepper with gears.<\/li>\n<\/ol>\n

        Weaknesses:<\/strong><\/p>\n

          \n
        1. No feedback: which is a weakness common to all 3D printers<\/li>\n
        2. Low stepper motor holding torque: Which causes the stepper to skip steps when encountering too much resistance<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
