Heater for filament extruder. by tunnelplan

Last crawled date: 3 years, 1 month ago

I used a soldering iron Parkside (cheap from Lidl 12 Euro) with adjustable temperature 48Watt.
The second is a soldering iron Lotring 30 Watt (Gamma 5 Euro) to start up the heating the first 15 minutes.
Tube 320 mm length 21,5/16,2 mm diameter.
Hopper Thing 152380.
Use a copper wire and a hose clamp for assembly.
Then isolate.
Temperature test results.

minutes x=on 0=off degree Celcius.
Adjust the soldering iron (48 Watt) to 4,7 and the themperature will stay at 200 degree Celcius
Next step is testing with granulate.
Is there a cheap granulate adress somewere in the Netherlands? Thank you!
