How to clean your PEI 3D printer plate
-
Preparation :
- Find a mild sulfur dissolved in water, hand soap or isopropyl alcohol (household alcohol)
- Have paper or a sponge ready.
When using sulfur or hand soap:
-
Wash the plate
- Apply a small amount of soap to the paper or sponge.
- Wash the entire PEI sheet thoroughly. Make sure to cover the entire surface.
-
Rinse with water
- Rinse the plate with water to remove the soap.
- Repeat washing and rinsing 1-2 times to ensure the plate is completely clean.
-
Final rinse :
- Rinse the plate thoroughly with plenty of water to remove all soap residue.
-
Drying :
- Let the plate air dry, or dry it with a clean piece of paper.
When using isopropyl alcohol :
-
Wash the plate
- Pour a little alcohol on a piece of paper towel and wipe the surface of the PEI sheet while it is cold and let the alcohol evaporate. Repeat 2-3 times.
And that’s it! Your PEI plate is now clean and ready to use. Remember to repeat this process regularly to keep your printer in tip-top shape. It’s good practice to never put your fingers on the plate, as the oil from your skin will settle on the plate and can create a hotspot where the filament won’t adhere. It doesn’t take much for things to go wrong. We usually wash our plates once a month, but it doesn’t hurt to do it more often.
Happy printing 🎉
