Complete the sentence to identify a common cause of stringing in 3D printing.
Stringing often happens because the printer's nozzle temperature is too [1].
When the nozzle temperature is too high, the filament becomes too runny and can ooze out, causing stringing.
Complete the sentence to describe a setting that helps reduce stringing by moving the nozzle quickly between print areas.
Increasing the [1] speed helps reduce stringing by minimizing oozing during travel moves.Travel speed is how fast the nozzle moves when not extruding. Faster travel means less time for filament to ooze out.
Fix the error in the sentence about a technique to stop oozing by reversing filament flow.
To prevent oozing, enable [1] which pulls filament back slightly when the nozzle moves without printing.Retraction pulls the filament back to stop it from leaking out during travel moves.
Fill both blanks to complete the advice on adjusting retraction settings to fix stringing.
If stringing occurs, try increasing the [1] distance and the [2] speed in your slicer settings.
Increasing retraction distance pulls filament back more, and increasing retraction speed pulls it back faster, both reducing stringing.
Fill both blanks to complete the dictionary comprehension that maps common fixes to their descriptions.
fixes = {[2]: '[1]' for [3] in ['retraction', 'travel speed', 'temperature']}This creates a dictionary where each fix is a key and its description is the value.
