Why Is Oozing Such an Issue for Multi-Extruder Printers?
Oozing happens when a nozzle isnt in use.

A single extruder is almost always in use, with rare retractions.
When the extruder is idling, the nozzle is still hot, and the filament is still kept there.
With the already molten filament being heated further, it gets runnier until it oozes out of the nozzle.
To some degree, oozing can be countered with retraction.
This is where the extruder pulls the filament back when its not being used.
By keeping it further away from the nozzle, its harder for it to ooze.
An ooze shield primes the nozzle at the start of each layer whilst also protecting your print from oozing.
The main downside of using an ooze shield is that it consumes extra filament.
Once your print is complete, the ooze shield should easily detach from the print bed.
Conclusion
Ooze shields are a great tool for protecting your prints from oozing-related artifacts.
