Filament Cleaning 1.75mm eSUN Tool for FDM 3D Printers Filament Change

• If you are constantly changing between PLA, PLA+, and PETG. This stuff is a must have! It is great for clearing out ABS when switching to PLA printing.
• Excellent heat stability, wide cleaning temperature range of 150 to 260 celsius.
• Cleans the extruder's interior by removing accumulated residual filaments.
• Possesses a certain level of adhesive quality. Will not clog extruder.
• Clean the 3D printer's extruder before and after printing for better extruder protection.

Fit for high & low temperature material conversion: When converting high and low temperature materials, the transition of this product can prevent the low temperature material from being thermally decomposed and blocked the nozzle, and can also avoid the high temperature material cooling and solidifying in the nozzle.

Functional:
1. Before and after printing, use this product to wash the machine;
2. When the high and low temperature materials are converted to each other, use this product to transition;
3. When printing different color materials before and after, use this product to transition;
4. Before and after printing performance difference When using two materials, use this product transition.

INSTRUCTIONS FOR USE ARE PRETTY VAGUE, BUT HERE IS WHAT ONE OF THE CUSTOMERS DO...

"As an example, say I am printing PETG at 245C and want to swap to PLA at 200C. I will raise my Z axis to about 100mm off the bed so I can see how the filament is coming out of the nozzle and heat up the hotend to 245C. Watching the temps as the hotend is heating, once I hit 200C, I would unload the PETG and then load up the cleaning filament. I would then extrude 10mm at a time until it looks like the PETG is purged and the extrusion comes out clear. I then do some wide temp cleaning by starting an extrusion of 50mm and set the hotend temp to 180. While the hotend is cooling, the cleaning filament is still flowing through the hotend.

If the 50mm runs through before I hit the target, I will just run 50mm more. I like to think I am just scrubbing the melting chamber... Am I really doing that? Not sure... :D

I would then perform the same procedure of running filament while it is heating back up to 245C and again back down to the target temp - at which time I load the desired filament and extrude until the cleaning filament is purged."
