I am currently very close to having a working Nurdle to filament extruder. So now some way of collecting the hot freshly extruded filament is required. My first thought was to automate an existing cable spindle so that it slowly rotates to … Continue reading
The Nurdle Extruder is still slowly progressing. Just to reiterate, the purpose of this extruder is to take food grade HDPE nurdles and produce a 3mm filament which can be spooled for later use on a geared reprap extruder. As … Continue reading
The same friend who has been bringing me the HDPE nurdles recently brought me a new and improved extruder head that he had made in his spare time at his work. As you can see, its a tad more professional looking than … Continue reading
It was recently questioned by Giles Bathgate as to why I don’t use the AC motor to drive the auger in the granular extruder. My first response was that I couldn’t adjust its speed and it would be difficult to gear down. However after some more time … Continue reading
I pulled apart the extruder today to take a look inside and I also made a few measurements of the extruded filament. The filament has swelled a little, but not as much as I thought. The die diameter is 2mm and … Continue reading
After my previous failings at using using solder to cap an extruder barrels open end I have now turned to brazing. The solder method may have worked but it turns out I don’t have any high temperature solder and it was just … Continue reading
