Pinterest LinkedIn Tumblr

As you may know, there are many factors that affect the quality of a 3d print. We often focus on the most common factors such as type of 3d printer, filament, temperature, 3d printing speed, slicing quality… However, a very common but often overlooked factor is poor bed adhesion, which often happens because the printer bed is dirty, and not cleaned properly. 

Why do we need to clean the printer bed

If the print bed surface is not clean and has good adhesion, the 3d printed object may detach from the surface in the middle of the printing process (Read this to find the solution for 3D Print Not Sticking to Bed).

That’s why we need to ensure our printer bed is clean before we start any 3d printing task. Remember to always clean the printer bed after removing the 3d printed object from the build plate.

Clean Bed Vs Not Clean Bed

In this article, we will go through every step to properly clean 3d printer bed surface. There’ll be a separate tutorial for every common type of 3d printer bed like PEI, Glass, Adhesive Tape, Polypropylene, Anycubic Ultrabase, BuildTak 

Now, let’s get started!

Type of 3d printer bed

There are various types of 3d printer beds on the market, each is made from different types of materials. Therefore, depending on the type of printer bed, there will be different cleaning methods.
Here are the most common types of 3d printer beds.

  • PEI printer bed: PEI stands for Polyetherimide, an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Today, many 3d hobbyists are using PEI printer bed because of its adhesion and chemical stability. If you are using

  • Anycubic ultrabase 3d printer bed: Anycubic ultrabase is originally a 3d printer bed integrated within Anycubic 3d printer. Anycubic ultrabase has very good adhesion and also, it’s very easy to remove 3d printed objects off the surface after the print is finished. As this type 3d printer bed has so much love from the community, the provider decided to provide this 3d printer bed as a separate component. Today, many types of 3d printers support Anycubic ultrabase 3d printer bed.

Things To Prepare Adhesive Tape Bed

Adhesive tape is a cheap and easy-to-replace material for 3d printed beds. The most convenient way to clean the printer bed using adhesive tape is to use a metal spatula. Although it’s quite simple to clean the adhesive tape printer beds, there are a few points to keep in mind if you do not want to damage the printer bed or affect the quality of the 3d print.

Step 1: Use a metal spatula to clean up the remaining 3d printed material on the surface of the adhesive tape

Use A Metal Spatula To Clean Printing Bed

If the printer bed is clean and the adhesive tape surface is not damaged, simply use a soft cloth soaked in alcohol and gently wipe it again.
If the panel is scratched or peeled, skip to step 2

Step 2: In case the adhesive printer bed surface is peeled or scratched, we need to patch the damaged area or replace the entire surface of the adhesive tape.

Remove Adhesive Tape From Printing Bed

Use your hands to peel off the damaged adhesive tape on the surface first. Next, use alcohol or soap to soak the microfiber towel and wipe away any remaining adhesive.

Step 3: Once the surface has been cleaned, use the new blue tape you prepared to apply to the printer bed surface.
Make sure the replacement tape surface is flat so that the 3d printed object does not detach from the surface during the printing process. When applying the new tape, remember to rub the surface to ensure that no air bubbles remain.

Polypropylene 3d printer bed

Things to prepare:


Microfiber Cloth 


Polypropylene is a polymer with high mechanical strength. In 3d printing industry, Polypropylene is a very popular material for printer beds because of its affordability and natural adhesion.

The method of cleaning the printer bed made of polypropylene is quite similar to that of glass. However, there are a few things you should keep in mind to avoid losing the adhesion of the printer bed surface.

Step 1: Remove the 3d printed object from the printer bed

Clean The Polypropylene Surface 1

Step 2: Clean the surface with a microfiber cloth soaked in 90% alcohol

Clean The Polypropylene Surface 2

Remember to use a soft cloth and avoid rubbing the surface vigorously because Polypropylene is not a scratch-resistant material. If the surface is warped, consider replacing it with a new Polypropylene sheet to avoid affecting the 3d printing quality.

In order to protect the ultrabase coating, do not make the following mistake.

  • Do not repeatedly wipe the ultrabase back and forth because it’s easy to leave oil stains on the ultrabase.
  • Do not wipe the ultrabase vigorously, it is easy to damage the ultrabase coating.
  • Do not immerse the ultrabase into a large amount of cleaning solution, which will damage the ultrabase coating
  • Ultrabase surface cleaning should not be carried out when the temperature is still high, which will affect the microstructure of the printer bed.

Somethings you should keep in mind

Depending on the type of material of the pinter bed, cleaning methods and chemicals are also different. Before cleaning the printer bed, it is recommended that users read the manufacturer’s cleaning instructions.
If there’s no instruction, use the appropriate cleaning method based on the material of the printer bed.
When cleaning the surface of the printer bed, always remember to use a soft cloth and avoid scratching and warping the printer bed. Otherwise, you will have to pay extra to replace the new panel.
