The nozzle is the heart of your extrusion system. This is the official Creality 0.4mm Brass Nozzle, specifically designed for the high-flow hotend found in the K1 Max 3D printer. A worn or clogged nozzle leads to under-extrusion and poor surface finish; replacing it regularly is key to maintaining print quality.
This genuine brass nozzle offers excellent thermal conductivity and the standard 0.4mm diameter for reliable performance with common filaments. For users pushing the K1 Max to its speed limits, having a fresh, factory-spec nozzle ensures that molten plastic flows exactly as intended, resulting in stronger, cleaner parts. It’s a simple, high-impact maintenance item we always keep stocked
