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
Something that has become painfully obvious over the last week is that handling granular HDPE is a very messy business indeed. These plastic nurdles, as i just discovered they are called, act a bit like sand in that they get into everything. … 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
