When would I use an extended nozzle?

You would use an extended length nozzle when you need more precise control over filament flow, especially with certain materials that require longer cooling or mixing times within the extruder. Extended nozzles can also help improve the consistency of the extrusion and reduce backpressure, particularly when dealing with more viscous or sensitive materials. They are typically useful for higher-quality filament production or when working with complex or specialty polymers
