Heater for filament extruder.

I employed an affordable Parkside soldering iron (12 Euro from Lidl, 48W, adjustable temperature) and a Gamma Lotring iron (5 Euro, 30W) to kick-start heating for the initial 15 minutes. The tube utilized had a length of 320mm and a diameter of 21.5/16.2mm. I assembled the components using a copper wire and a hose clamp. Subsequently, I isolated the setup. Test results indicate temperature variations based on time and wattage: at 48W, temperatures were 20.6°C and 20.1°C after 5 minutes; at 30W, they reached 43°C and 21.4°C at the same time. After 10 minutes, temperatures were 130.5°C and 22.7°C. At 15 minutes, they spiked to 195.3°C and 30.5°C, then plateaued at 204°C and 45.3°C after 20 minutes before rising again to 208°C and 51.2°C at 25 minutes. Temperatures stabilized at 213°C and 50.7°C at 30 minutes, dipped to 192.5°C and 59.5°C at 40 minutes, then climbed back up to 191.8°C and 60°C at 45 minutes before leveling off at 208°C and 60.3°C at 55 minutes. Temperatures reached 215°C and 60.2°C after an hour, and remained steady at those levels for the next two hours (210°C and 61.7°C at 120 minutes). The Parkside iron's temperature was adjusted to 4.7W, resulting in a consistent 200°C. Next, I will test functionality with granulate. If anyone knows an affordable granulate source in the Netherlands, please let me know! Also, check out this thing (http://www.thingiverse.com/thing:250594) and Tunnelplan.nl for more information.
