Ender 3 by Creality is a versatile low cost 3D printer that can sit on your desk without impeding on your space too much.
The stock standard white filament that comes in the box may be a little too boring for your printing requirements.
Thats why I have made this simple to follow ender 3 filament replacement guide you can follow.
Changing your filament colour can really make your 3D print pop with detail and give it a completely different look.
The process to change filament type and colour is the same on the Ender 3 but there are a few things to be aware of before you get started.
Just follow these simple steps and you’ll be printing in a different material/color in no time.
Step 1 Remove Old Filament
Begin by heating up the nozzle to the melting temperature of the type of filament
Here are melting temperatures for the most commonly used filaments:
PLA: 180°C – 230°C
ABS: 210°C – 250°C
PETG: (PET, PETT): 220°C – 250°C
Nylon: 240°C – 260°C
TPU,TPE,TPC (Flexible) 210°C – 230°C
PC (Polycarbonate 270°C – 310°C
I’m using PLA with my Ender so use 200°C. Check out this video to see the process.
To heat up the nozzle on your Ender 3 scroll to Control Settings > Temperature > Nozzle > Move Knob To Increase Temp > Push Knob To Set
Once the hot end has reached the desired temperature you will notice filament starting to come out the nozzle.
Push the extruder lever to release tension on the filament and slowly pull the filament out completely.
After it’s all the way out thread it through the filament roll holes to make storage MUCH easier.
Here is a video to show exactly how you remove the filament once the hot end is up to temperature:
Your Ender 3 is now ready to accept a new type of filament of your choosing.
Step 2 Installing the New Filament
Mount your new roll of filament to the Ender 3 filament holder.
Cut the end of the filament on an angle to make it easier to feed through the hole in the extruder.
Filament that you unroll from the spool won’t be perfectly straight which can make it tricky to insert through the extruder.
To simplify this process straighten around a 5cm (2inches) of filament.
Push in the extruder lever to make sure there is no resistance when inserting the new filament.
Insert the filament through the extruder and bowden tube until you feel resistance.
When you feel resistance you have reached the nozzle, insert a little more filament until you see melted filament coming out of the extruder.
Now release the extruder lever to put tension on the filament.
Step 3 Purging the Nozzle
Before printing with your new filament it’s a good idea to purge your nozzle to remove any leftover filament left inside.
Pro Tip: If you are changing filament to a lower melting point material, keep the nozzle temperature set higher until purging is completed.
A feature of the Ender 3 allows you to completely purge the old filament from the nozzle.
Use the control knob to navigate to the software feature in settings:
Move Axis > 1mm Nozzle > 15 to 20
Once selected the printer will feed filament through the nozzle until you see the new colour or type of material coming out the end of the nozzle.
If you are still seeing the old type of filament, repeat the purge process until it’s all gone and only new filament is seen coming out.
You’re all set!
You’re ready for a new 3D print, just a quick tip before you load your next file to print.
Make sure you adjust the printer settings before printing if the filament has a different melting point!
Happy creating 🙂
