Modicum Extruder V1: Finally

Finally working production extruder.

After close to a dozen iterations, and probably around 6 printed variations I am proud to say that my extruder is now complete.

As mentioned in my earlier blog post. This was the design goal.

  • High precision
  • Small in size
  • reproducible with standard parts, no machine work.
  • easy to 3d print
  • quick to 3d print.
  • low time investment in assembly.
  • KISS Standard.

I am very pleased with my results. So far the printer went from 50mm/s top speed to 100mm/s outer shell speed and 120mm/s infill speed. The extruder does not skip.

Here are a few images of the extruder.
