Choose a nozzle by hardware system, material, and required feature size. A nozzle that physically fits is not necessarily supported by the hotend or slicer profile.
Diameter tradeoff
Prusa states that nozzles larger than 0.6 mm can print thicker and taller lines faster, but with reduced fine-detail resolution. Smaller nozzles favor detail but need compatible profiles and can be unsuitable for filled or flexible materials.
Abrasive materials
Prusa's table marks hardened nozzles for listed wood/metal-filled and carbon/kevlar-filled materials. Verify the exact product: base polymer, filler, particle size, and minimum diameter differ.
Before changing a nozzle
Confirm thread/geometry, hotend support, material compatibility, slicer profile, and calibration requirements.
