$10 Upgrade for FASTER Creality CR-10 Prints

With this simple upgrade to your CR-10 printer, you can cut print times significantly.

 

This article covers an easy, cheap modification for your Creality CR-10 printer that can significantly reduce print times for complex objects like highly detailed armor pieces. The fix? Changing out the stock nozzle your printer came with. Depending on the style of your printer, this may also work with non-Creality printers so long as the nozzle can be easily changed. The Creality CR-10 is outfitted with a .4 mm nozzle, and upgrading this nozzle to a 1 mm nozzle reduces the number of shelves required at each pass, which can slash print times.

Step 1: Check nozzle temperature

Before attempting to change the nozzle, go into your printer settings and turn up the nozzle temperature to about 180 ℃. Heating the nozzle allows for any filament in the nozzle to be pulled out. Ensure that all remaining filament in the nozzle has been removed before proceeding.

Step 2: Remove the fan(optional)

You don’t need to remove the fan to replace the nozzle, it just makes it easier to access the nozzle. To access the nozzle, the fan must be removed. To unmount the fan, unscrew the two small screws that secure the fan to the printer body:

Step 3: Unscrew the original nozzle

Before attempting to remove the nozzle, it is important to secure the hot end (circled below) to ensure it does not move during the process. We recommend using a small rag and/or pliers to keep it in place. Remember, this part has been heated, so avoid touching it directly.

After securing this part, take the small wrench that came with your printer and unscrew the nozzle.

Step 4: Install the new nozzle

While the hot end is still heated, screw in the new nozzle. Use the small wrench to tighten it.

Step 5: Remount the fan

Simply replace the fan to its original location and screw in the two mounting screws.

Test times and settings

To demonstrate the dramatic difference in print speed caused by this minor fix and check the quality, we conducted a test print.

Here are the original print settings for the .4 mm nozzle:

Note that for this smaller nozzle, we needed at least 3 shells to get solid layers for this print. This inevitably leads to longer print times. Using these settings, we got an estimated print time of around 22 hours.

Compare the settings above to the new settings for the larger nozzle:

With the new nozzle, only 1 shell is needed, which drastically cuts the time taken to complete each layer. Note also that the temperature was lowered from 245 ℃ to 220 ℃ to reduce stringing. The best temperature setting will depend on the filament you are using as well, so be sure to run a test print with your starting settings before working on a larger piece.

Owing to these changes, we cut the time for our armor print by more than half with no quality loss. The only thing to note is that the smaller details that you might want might get lost with a bigger nozzle.

That’s it! This process takes around 15 minutes and can save you hours. You can get variety nozzle sets from Amazon for under $10. Note that the larger layers may lead to some rough surfaces depending on your model shape. This issue is fairly minor and can easily be addressed with some quick sanding.
