By adding simple isolation around the nozzle we managed to increase the nozzle temperature from 60 up to 170 degree. Definitely one of the most simple upgrad...

After many months of developing and testing to master the PE/PP material from household waste, our gathered data indicate that we will not be able to produce...

Since the extruders end had an unusual external thread size for attaching nozzles, we decided to remove the end and replace it with a more common fitting. Th...

Earlier we announced a large upgrade of the extruder. One major challenge was to increase the amount of heating zones from 2 to 4. Splitting the zones was ne...

We found this interesting research on the relation of extruder screw geometries, melt viscosity and thermal efficiency. Highlights: • Radial melt temperature...

Since the extruder is an oldy, it was about time to give it a good clean. For maintenance of the barrel we used cleaning purge. Purging the extruder is advis...

With the installment of couplers and nozzles the quality of the output greatly improved. Since recycled plastics from household waste are used we are excited...

In PE/PP Testing v1 the layer height was set between 5 – 8 mm, resulting in thick round layers. The material has less surface for cooling and remains longer ...

To vertically hold the extruder in place a standard was built. This enables to attach the extruder to the robot more easily. After welding the frame together...

The motor driven feeder arrived to tackle our feeding problems. Unfortunately, the included motor seems not suitable for integration within our set-up. We do...

The upgrade of the extruder has been finalized. Big thanks to Rohaco! The extruder set-up is now separated from the controlling unit, making it possible to a...

The first tests with the extruder are executed. All is working well, however there is still a lot of work to do before the extruder can be used for 3D printi...
