Need a new nozzle for your 3D printer? It’s important to review your needs before selecting a nozzle carefully. The smaller nozzles have a small nozzle tip that offers incredible precision, while the larger nozzles allow you to print with larger layers. You can easily identify all the nozzles by looking at the markings on the flats of the hex head.
This is a bundle of 10 pcs of nozzles with 5 different sizes:
All these MK8 thread nozzles are suitable for Creality Ender and CR Series 3D Printer (EXCEPT CR-10S PRO and CR-X).
How to choose the nozzle size?
The most common nozzle size used is 0.4 mm because it provides a good balance between print speed and precision. But small and big nozzle size has their own pro and con. Generally, this table shows the guideline for you to choose the size depending on your application. For more details about the nozzle size explanation, you may refer to the article "Everything about nozzles with a different diameter" by Mikolas Zuza (blog.prusaprinters.org).
Note: Remember to change your nozzle size in your slicer setting if you change the nozzle size (0.4mm is the default size for most of the slicers). You will be shocked when you observe the reduction of printing time by changing the bigger size (in slicer) for your huge printing part.
Basically, the different size of nozzles affects your printing resolution on X and Y axes only. Z-axis resolution still depends on your slicer setting (printing resolution or printing layer height). However, the max printing layer height is limited by nozzle size, the formula for the recommended max layer height = 0.8(or 80%) x nozzle size.
