If you want to get the best quality results from your 3D printer, one of the most important factors to consider is bed adhesion.
3D printer bed adhesion is what ensures your finished product sticks firmly to the build platform during printing, and if that isn't adequately secured – even if it gets started without any issue – it could throw off your entire print.
In this blog post, we'll share our top tips for improving the bed adhesion of your 3D prints so you can ensure consistent success with each one.

What is 3d printer bed adhesion?
3D printer bed adhesion refers to the ability of a 3D printed object to stick to the surface of the print bed during the printing process. In order to create a successful 3D print, the first layer of the object needs to stick to the print bed without shifting or lifting. Proper bed adhesion is critical for creating high-quality prints that are accurate and stable.
There are several factors that can impact bed adhesion, including the material of the print bed, the temperature of the bed, the printing speed, the type of filament being used, and the shape of the object being printed.
In order to ensure good bed adhesion, it's important to properly prepare the print bed before starting the print, and to adjust the settings on the 3D printer to optimize adhesion based on the specific materials and objects being used. Some common techniques used to improve bed adhesion include cleaning the print bed, applying adhesives or coatings to the bed surface, adjusting the bed temperature, and using a brim or raft to help the object stick to the bed.
3D printer bed adhesion problems and troubleshootings
Here are some common 3D printer bed adhesion problems and their possible solutions:
Problem 1. The print is not sticking to the bed
If the first layer of the print is not sticking to the bed, it may be due to an unlevel print bed or inadequate bed adhesion. Make sure the print bed is level and clean, and try using a bed adhesive such as glue stick or hairspray. Adjusting the bed temperature can also help improve adhesion.
Tips: fix the 3D print not sticking to the bed.
Problem 2. The print is sticking too well to the bed
If the print is sticking too well to the bed and is difficult to remove, it may be due to a bed temperature that is too high or the use of an adhesive that is too strong. Try reducing the bed temperature or using a weaker adhesive.
Problem 3. The print is warping or lifting
If the print is warping or lifting off the bed during the print, it may be due to a bed temperature that is too low, or a print bed that is not level. Try increasing the bed temperature or leveling the bed more carefully.
Problem 4. The print is coming out uneven or distorted
Uneven or distorted prints may be due to an unlevel print bed or an improper first layer height. Make sure the print bed is level, and try adjusting the first layer height in the printer settings.
Problem 5. The print is curling up at the edges
Curling at the edges of a print can be caused by a variety of factors, including inadequate bed adhesion, poor cooling, or excessive heat. Try adjusting the bed temperature, increasing cooling, or using a brim or raft to help the object stick to the bed.
Problem 6. The print is shifting during the print
Shifting during the print can be caused by a variety of factors, including an unlevel print bed, excessive printing speed, or improper belt tension. Make sure the print bed is level, reduce the printing speed, and check the belt tension.
Remember, different 3D printers, materials, and objects may require different bed adhesion solutions, so it may take some experimentation to find the right settings for your specific needs.
How to improve your 3D printer bed adhesion results
There are several ways to improve 3D printer bed adhesion results:
- Clean the print bed: Before starting a print, make sure the print bed is clean and free of any debris. Use a clean cloth and some isopropyl alcohol to wipe the bed clean before printing.
- Use a bed adhesive: Bed adhesives such as glue sticks, hairspray, or specialized bed adhesives can help improve adhesion. Experiment with different types to find what works best for your printer and materials.
- Adjust the bed temperature: Adjusting the bed temperature can help improve adhesion. For example, if you are printing with PLA, try setting the bed temperature to 60°C.
- Level the bed: Make sure the bed is level before printing. A misaligned bed can cause adhesion issues.
- Use a brim or raft: A brim or raft is a small extension of the print that helps increase adhesion. This is especially useful for prints with a small base.
- Slow down the print speed: Printing too fast can cause the print to come loose from the bed. Try slowing down the print speed to improve adhesion.
- Use a different bed surface: If you are still experiencing adhesion problems, consider using a different bed surface. Some popular options include glass, BuildTak, and PEI sheets.
- Use a heated chamber: For materials that are difficult to print, such as ABS, using a heated chamber can help improve adhesion.
- Add a brim or skirt to the print: This can help increase the surface area of the print and improve adhesion.
- Check the filament diameter: Make sure the filament diameter is set correctly in the printer settings. If it is too thin, it may not stick properly to the bed.
By experimenting with these different techniques, you should be able to find the right combination of settings and materials that will help improve your 3D printer bed adhesion results.
What is the best adhesive for 3d printing bed?
The best adhesive for 3D printer bed can vary depending on the specific printer and materials being used. Some common types of adhesives that are often used include:
- Glue stick: A glue stick is a popular choice for improving bed adhesion, especially for printing with PLA. Simply apply a thin layer of glue to the print bed before starting the print.
- Hairspray: Hairspray is another popular adhesive for improving bed adhesion, particularly for ABS and PETG. Simply spray a thin layer onto the print bed before starting the print.
- Kapton tape: Kapton tape is a type of polyimide film that can be applied to the print bed to improve adhesion. It is particularly useful for printing with ABS.
- BuildTak: BuildTak is a specialized adhesive sheet that can be applied to the print bed to improve adhesion. It is particularly useful for printing with materials that are difficult to stick to the bed.
- PEI sheets: Polyetherimide (PEI) sheets are another type of adhesive sheet that can be used to improve bed adhesion. They are particularly useful for printing with ABS and PETG.
Improving bed adhesion results on a 3D printer can often be a daunting challenge; however, with the right adjustments and materials, you can make it much easier.
Hopefully using these tips will help you get good bed adhesion every time.
