Instead of laying down material to build parts, it acts as a maintenance tool: running it through your system helps remove residue from previous prints and any oozed or burnt filament that might be degrading performance. Key Benefits As filament residue (such as carbonized plastic, burnt particles, or old material) can build up in the hot-end area of your printer, it could compromise flow, cause underextrusion, or even completely clog the nozzle. Regular use of cleaning filaments like eClean helps maintain consistent extrusion, improved print quality, and reduces the risk of failed prints due to blockages. Technical Specifications Diameter: 1.75mmWeight: 100gRecommended Use Temperature: 160-300 °CColor: Natural (undyed) Usage Tips Heat the nozzle to a temperature in the recommended range that matches the previously used material (or slightly higher). Insert the eClean filament and slowly extrude it until you observe a clean and consistent flow. If residue is particularly stubborn, let the filament sit for a short time at a higher temperature, then purge. After cleaning, resume with regular filament, ensuring it is properly positioned for best feeding. Packaging and Storage The eClean spool is vacuum-sealed to keep moisture, dust, and other environmental contaminants away before use. This helps maintain its cleaning effectiveness and ensures reliability when you need it. Store in a dry place after opening. eSUN eClean is a cleaning filament designed to keep your 3D printer's nozzle and extruder free from buildup. With a recommended operating temperature of 160 to 300 °C, it can remove residue from a variety of filament types. The filament is vacuum-sealed to protect it from moisture and contamination. Ideal for improving filament feeding consistency and reducing clogging. Key Features Cleans accumulated filament residue in the hot-end Helps prevent nozzle clogging Wide temperature range (160-300 °C) Suitable for many filament materials Ensures smoother filament feeding Vacuum packaging for moisture and dust protection\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e eSUN\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eModel:\u003c\/strong\u003e Clean175W01R1\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 6922572242418\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eBuy eSUN Cleaning Filament at STRATO3D with fast shipping in Italy.\u003c\/em\u003e\u003c\/p\u003e","brand":"eSUN","offers":[{"title":"Clean175W01R1","offer_id":55704322376020,"sku":"Clean175W01R1","price":9.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0957\/4331\/2212\/files\/Esun-Cleaning-Filament-33512.jpg?v=1777884115"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0957\/4331\/2212\/collections\/Esun-Cleaning-Filament-33512.jpg?v=1779741215","url":"https:\/\/strato3d.it\/en\/collections\/filamenti-cleaning-filament.oembed","provider":"Strato3D","version":"1.0","type":"link"}
