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.
- NO LASH
- 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.
