3D Printer Bed Adhesion: A Complete Guide

It’s no surprise that in the world of 3D printing, bed adhesion is one of the most important steps to getting it right. If you want parts that stick while they print and don’t warp or curl around your build plate, then ensuring good bed adhesion should be a top priority. 

In this complete guide, we cover everything from surface preparation and selecting an adhesive, to applying the adhesive correctly and inter-layer peel strength testing every step of the way – so you can have great first-layer adherence with all your 3D prints!

The ability of a 3D printer to maintain bed adhesion is important for a variety of reasons. One of the most important reasons is that it helps to ensure that the print is successful. 

If the printer cannot maintain a good bed adhesion, then the print may come loose from the bed and cause defects in the final product. This can be especially problematic with more intricate prints, where even a small defect can ruin the entire object.

Another reason why bed adhesion is important is that it can help to improve the quality of the final product. When the printer has a good hold on the object, it can produce cleaner prints with fewer defects. This is because there is less chance for the object to move around during printing, which can cause smearing and other quality issues.

Finally, bed adhesion is also important because it can help to reduce warping. Warping occurs when the plastic filaments used in 3D printing start to cool down and contract. This can cause the object to warp or curl, which can lead to defects in the final product. By having a good bed adhesion, you can reduce the chances of warping occurring, which will result in a higher-quality print.

What factors affect 3D Bed Adhesion?

There are several factors that can affect 3D bed adhesion, including surface characteristics, material properties, and environmental conditions.

  • One key factor is the surface characteristics of the 3D printing bed. This includes things like the texture and smoothness of the printer’s build platform, as well as any adhesives or coatings used on the bed to improve its grip. 
  • Factors such as temperature can also have an impact on 3D bed adhesion since they can affect the print material’s properties and viscosity. 
  • In addition, environmental conditions such as humidity or air pressure can play a role in 3D bed adhesion by affecting how well the print material sticks to the printer’s build platform.

Understanding these different factors and how they can impact 3D bed adhesion is important for achieving consistent, high-quality prints. 

Fortunately, there are a number of strategies that you use to troubleshoot and improve 3D bed adhesion, such as optimizing your’s settings or experimenting with different materials and print surfaces. Ultimately, the key to successful 3D printing is finding what works best for your specific setup and preferences. You have to ensure that your 3D slicer is set up correctly too.

So if you’re struggling with 3D bed adhesion, don’t worry – there are plenty of tools and tips at your disposal to help you achieve great results. With some experimentation and patience, you’ll be able to find a solution that works for you!

How can you improve bed adhesion?

There are a few things that you can do in order to improve bed adhesion. 

  • One of the most important is to make sure that your bed is level. You can use a calibration square to check this, and if it’s not level, you can adjust the screws on the bottom of your printer until it is. 
  • Second, you should also make sure that your print surface is clean and dry before printing. If there is any dust or debris on the surface, it will cause the filament to stick to it instead of sticking to the bed. You can clean it with a lint-free cloth or with a spray bottle filled with distilled water.

What are some common problems with bed adhesion?

There are a few common problems that can occur with bed adhesion. 

  • One of the most common problems is delamination, which is when the adhesive layer between the bed and the print surface falls apart. This can be caused by a variety of factors, including incorrect bed leveling, incorrect filament type or diameter, and incorrect temperature settings.
  • The second common problem is warping, which is when the print surface becomes distorted due to uneven heating. This can cause the print to become detached from the bed or completely detach from the printer itself. Warping can be caused by a variety of factors, including incorrect temperatures, drafts, and humidity levels.
  • Bed adhesion can also be affected by contaminants on the print surface. This can include oils from your hands, dust, or even pieces of plastic from previous prints. 

These contaminants can interfere with the adhesive layer between the bed and the print surface, causing prints to come loose or warp.

How can you test bed adhesion strength?

Bed adhesion strength is a measure of how well a material sticks to a surface. This property is important for many applications, such as in adhesives, coatings, and sealants. There are several ways to test bed adhesion strength, but one of the most common is the peel test.

In the peel test, a strip of material is attached to a substrate and then pulled away from it. The force required to pull the strip away is measured and used to calculate the bed adhesion strength. This test can be performed on a variety of materials, including plastics, metals, and composites.

The peel test is a quick and easy way to measure bed adhesion strength, but it does have some limitations. For example, it cannot be used to test the adhesion of flexible materials. Additionally, the results can be affected by factors such as temperature and humidity.

Despite its limitations, a peel test is a useful tool for assessing bed adhesion strength. It can be used to compare different materials or to evaluate the effectiveness of an adhesive or coating.


Now that you understand more about bed adhesion and its importance in 3D printing, as well as the various factors which affect it, you should have no trouble achieving strong adherence on your print beds.
