Simple Method to Change or Replace Your 3d Printer Nozzle?

The nozzle is one of the most important components of a 3D printer, which might not seem so important but it plays a very important role in the quality of your 3D prints. Just to show a comparison, it’s like a pen’s nib, the better the nib, the better the writing and consistency. Like that, a good-quality nozzle is important. But over time, these 3D printer’s nozzles wear down and need to be changed. Here is a detailed guide on how you can change your 3D printer’s nozzle.

How to change/replace a 3d printer nozzle?

Changing a 3D printer’s nozzle is pretty simple. First, make sure you are wearing gloves for safety. Then, heat the nozzle to 240 degrees Celsius. Remove the ol filament. Use an adjustable wrench and socket (mainly a hexagon socket). Hold the heating block with the adjustable wrench and unscrew the old nozzle that needs to be replaced. Next, take a new nozzle and screw it in using the socket. Make sure the hotend is hot wjile screwing the new nozzle so that it can be tightened properly.

Reasons you might want to change the nozzle

There are many reasons why people change or replace nozzles. Here are the five common reasons behind changing your 3D printer’s nozzle:

Wear and tear: It is the most common reason to change the nozzle because nozzles have tendency to wear out over time due to which your print quality degrades which results in poor print quality and inconsistent extrusion.

Clogging: One of the most annoying reasons that forces people to change their 3D printer’s nozzle is clogging. Clogging happens when your nozzle gets blocked and stops the flow of filame and It can be fully or partially clogged which will lead to failed prints. The main reason for clogging is filaments which contain particles or impurities, or dust that accumulated on your filaments over time which was kept in the open.

Changing Filament Type: Sometimes, different filaments require different nozzles. For example, if you want to print advanced materials like Nylon, carbon fiber, or Hips, you might need to change your default brass nozzle to a hardened steel nozzle that can withstand temperatures at or above 300 degrees Celsius.

How to change or replace the nozzle

Collects the Tools: To change the Nozzle of your 3D printer’s you will need these tools.

  • Replacement Nozzle
  • Nozzle size Wrench or socket (usually comes with your 3D printer)
  • Gloves (for safety)
  • Adjustable Wrench

Preheat the nozzle: First thing you need to do is to preheat the nozzle to the melting temperature of the filament which is currently in hotend. From my personal experience, I heat the nozzle to 240 degrees Celsius to completely melt the filament from the heating block’s threads.

Remove the Filament: Once you have heated your nozzle, unload the filament by pressing the extruder to release its grip from the filament, then pull it in the opposite direction of the hotend.

Unscrew the Nozzle:  Now it’s time to unscrew the nozzle using a wrench or socket, but make sure to wear gloves to prevent burns on your fingers in case of mishaps.Keep the hotend hot at the required temperature, then use the the adjustable wrench to hold the heating then use the socket or wrench to unscrew the nozzle until it comes off but in some cases it hangs from the heating block due to filament in heating block then in that case take a plier and pull i

Screw the nozzle: Before you start screwing, make sure your 3D printer’s hotend is around 240 degrees Celsius. Then, place the new nozzle in the socket and again hold the heating block with an adjustable wrench and start screwing it in. make sure you tight it properly so that it won’t leak and dont put too much force while tightening otherwise you might break the heatbreak

Conclusion

Changing the nozzle is a pretty simple and easy process. It is recommended to replace the 3D printer’s nozzle after every 50 to 100 hours of printing or replace when you start facing issues like underextrusion, clogs, uneven flow, or poor print quality. The above guide provides the simple and easy-to-follow steps for changing the 3D printer’s nozzle.
