Review on 🧽 ESUN CLEANING Filament: Optimal Solution for Printer Cleaning by Larry Morris

This makes cold drawing easier. You have to do this a little differently than with nylon or ABS: heat the hotend to the temperature of the filament to be cleaned. Then slide in enough cleaning floss until it becomes transparent. Then allow the hot end to cool completely. Reheat to 90°C, then pull firmly but gently. don't hold on Just keep constant upward pressure. As the filament heats up, it begins to pull upwards, effectively thinning the filament and pulling it away from the walls and nozzle of the thermal break. It will then free itself and you will get a reward by seeing all the crude oil that was trapped down there. You really only need to do this once in a while unless you use a dust filter on your filament (which you should be). The design of the hot end assembly on one of my printers allows for a nylon or ABS cold pull which will fail about 80% of the time and break the filament just above the thermal break, but this material has enough strength to get through the tight spots get.
