How to fix stringing in infill 3D models?

To fix stringing in infill 3D models, focus on four key adjustments—retraction, temperature, infill pattern, and nozzle cleanliness—to stop molten filament oozing, the main cause of messy strings. - Increase retraction distance/speed: Pulls filament back during travel, preventing oozing between infill lines. - Lower nozzle temperature slightly: Cools runny filament, reducing leakage between lines. - Use short-travel patterns (e.g., gyroid): Shorter moves mean less time for filament to ooze. - Clean the nozzle: Removes clogs that disrupt flow and worsen stringing. Combining these steps will eliminate most infill stringing for cleaner 3D prints.
