\"3D<\/p>\n

Stringing (also called oozing or cobwebbing) occurs when molten filament leaks from the nozzle during non-printing travel moves, creating thin plastic threads between different parts of your print.<\/p>\n

Primary Causes of Stringing<\/h2>\n

The most common cause is insufficient retraction, where filament continues flowing during travel. Temperature too high results in lower viscosity and easier flow. Material characteristics matter\u2014PETG, TPU, and nylon are naturally prone to stringing. Wet filament creates steam bubbles forcing material out. Slow travel speed allows more time for oozing.<\/p>\n

Optimal Retraction Settings<\/h2>\n

For PLA, use 4-6mm at 25-45mm\/s. PETG works best at 3-5mm at 20-30mm\/s. ABS needs 5-8mm at 35-50mm\/s. Nylon requires 3-5mm at 25-35mm\/s with thorough drying first. Our PA6-CF Filament<\/a> is optimized for clean printing.<\/p>\n

Slicer Settings That Help<\/h2>\n

Enable coasting to stop extrusion before travel. Use wipe to clean nozzle on printed surfaces. Activate combing to route travels through printed areas. Increase travel speed to 100-150mm\/s for less time to ooze.<\/p>\n

Source Quality Filaments<\/h2>\n

As a specialized source manufacturer, we supply filaments with tight diameter tolerance (\u00b10.03mm) for consistent printing. Contact us<\/a> for samples.<\/p>\n
