When it comes to preventing 3D prints from sticking too well to the print bed, applying adhesives is a common practice. However, not all adhesives are created equal. Here are some of the most popular adhesives used in 3D printing:
Using a glue stick is a simple and affordable way to keep your prints from sticking to the print bed. It is especially effective for PLA and PETG filaments. Here’s how to use a glue stick:
- Clean the print bed with rubbing alcohol or soap and water.
- Apply a thin layer of glue stick to the print bed. You can apply it in a grid pattern or cover the entire bed.
- Wait for the glue to dry before starting your print.
Hair spray is another popular adhesive used in 3D printing. It is effective for ABS filaments, which tend to warp and lift from the print bed. Here’s how to use hair spray:
- Clean the print bed with rubbing alcohol or soap and water.
- Spray a thin layer of hair spray onto the print bed. You can apply it in a grid pattern or cover the entire bed.
- Wait for the hair spray to dry before starting your print.
ABS juice is a mixture of ABS filament and acetone. It is used to create a sticky solution that helps keep ABS prints from warping and lifting from the print bed. Here’s how to make ABS juice:
- Cut some ABS filament into small pieces and place them in a glass jar.
- Add enough acetone to cover the ABS pieces.
- Stir the mixture until the ABS has dissolved.
- Apply a thin layer of ABS juice to the print bed. You can apply it in a grid pattern or cover the entire bed.
- Wait for the ABS juice to dry before starting your print.
Remember to use adhesives sparingly and only when necessary. Overuse of adhesives can cause your prints to stick too well to the print bed, making them difficult to remove.
Adjusting Bed Temperature
Adjusting the bed temperature is a common way to prevent 3D prints from sticking too much. The ideal temperature will depend on the type of filament you are using. Here are some tips for adjusting the bed temperature:
Lowering Bed Temperature
If your prints are sticking too well to the bed, try lowering the bed temperature. Gradually decrease the bed temperature in 5°C increments until you find the perfect temperature for your filament. This will help prevent the filament from sticking too much to the bed.
Raising Bed Temperature
If your prints are not sticking well to the bed, try raising the bed temperature. Gradually increase the bed temperature in 5°C increments until you find the perfect temperature for your filament. This will help the filament adhere better to the bed.
It’s important to note that adjusting the bed temperature is just one way to prevent prints from sticking too much or not enough. Other factors, such as the type of adhesive material used, the bed surface, and the calibration of the bed and first layer, can also affect how well the print sticks to the bed. Experiment with different settings to find what works best for your specific filament and printer.
Calibrating Bed Level
Calibrating the bed level is a crucial step in ensuring that your 3D prints stick to the build plate properly. It involves adjusting the height of the print bed to ensure that it is level with the nozzle. If the bed is not level, the first layer of your print may not adhere properly, causing the print to fail.
Here are some steps to calibrate your 3D printer bed:
Clean the bed surface: Before calibrating, clean the bed surface with Isopropyl Alcohol and a paper towel to remove any debris or leftover filament that may interfere with the calibration process.
Home the printer: Home the printer by moving the nozzle to the front left corner of the bed. This is usually done through the printer’s menu or software.
Place the calibration card: Place a calibration card or piece of paper between the nozzle and the bed at the front left corner. The card should be snug enough to feel some resistance when pulled out.
Adjust the bed height: Use the printer’s menu or software to adjust the bed height until the nozzle just barely grips the card. Repeat this process for the remaining corners of the bed.
Check the bed level: After adjusting the bed height, double-check the bed level by moving the nozzle to each corner of the bed and checking the distance between the nozzle and the bed with the calibration card. The distance should be consistent across all corners.
Save the settings: Once the bed is level, save the settings to the printer’s memory. This will ensure that the bed remains level for future prints.
By calibrating the bed level, you can ensure that your 3D prints adhere properly to the build plate, resulting in successful prints. It’s a simple process that can make a big difference in the quality of your prints.
Using a Raft or Brim
One effective way to prevent 3D prints from sticking too well to the print bed is to use a raft or brim. A raft is a thin layer of material that is printed first and serves as a base for the rest of the model to be printed on. A brim, on the other hand, is a thin strip of material that is printed around the base of the model, creating a larger surface area for the print to adhere to.
Using a raft or brim can help ensure that the first layer of the print adheres properly to the bed, as well as provide a more stable base for the rest of the model to be printed on. Here are some tips for using a raft or brim effectively:
- Rafts can be particularly useful for printing with materials that tend to warp, such as ABS or PETG.
- When using a raft, make sure to adjust your printing settings accordingly. For example, you may need to increase the distance between the nozzle and the bed to accommodate the extra layer of material.
- Some slicing software will automatically generate a raft for you, while others may require you to manually add one to your model.
- Brims can be useful for prints that have a small base or that require a lot of support.
- When using a brim, make sure to adjust your printing settings accordingly. For example, you may need to increase the width of the brim to ensure that it provides enough support for the print.
- Be mindful of the fact that a brim will add extra material to your print, which may affect the overall quality of the finished product.
Overall, using a raft or brim can be an effective way to prevent 3D prints from sticking too well to the print bed. By taking the time to adjust your printing settings and experiment with different techniques, you can find the approach that works best for your specific needs and materials.
Cleaning the Bed Surface

You can use a 70% or 90% solution of isopropyl alcohol to clean your bed. Simply pour some alcohol onto a lint-free cloth and wipe the bed surface thoroughly. Avoid using paper towels or tissues as they may leave behind fibers.
Acetone is another popular cleaning agent that can be used to clean the bed surface. However, it is recommended to use it only on glass or metal beds as it can damage other surfaces. Acetone is highly effective in removing any adhesive residue left behind by tapes or glues. Pour some acetone onto a lint-free cloth and wipe the bed surface gently. Make sure to wear gloves and work in a well-ventilated area.
3. Soap and Water
If you don’t have any cleaning agents available, you can use soap and water to clean your bed surface. Simply mix some dish soap with warm water and use a lint-free cloth to wipe the bed surface. Rinse the surface with clean water and dry it with a clean cloth. Make sure to avoid using abrasive sponges or scrubbers as they can scratch the bed surface.
4. Other Cleaning Agents
There are several other cleaning agents that you can use to clean your bed surface, such as window cleaner, vinegar, or hydrogen peroxide. However, make sure to test these agents on a small area first to ensure they don’t damage the bed surface.
In conclusion, keeping your 3D printer bed clean is essential for successful prints. Regularly cleaning your bed surface with the right cleaning agent can help prevent prints from sticking too well to the bed.
In conclusion, preventing 3D prints from sticking to the bed is crucial to achieving high-quality prints. The key is to find the right balance between adhesion and release. There are several ways to achieve this balance, including choosing the right adhesive material, changing the bed surface, calibrating the bed and first layer, creating a temperature difference between the print and bed, reducing initial layer speed and flow rate, and using a raft or brim on your 3D prints.
It is important to note that there is no one-size-fits-all solution to this problem. The best approach will depend on the specific printer, filament, and print settings being used. Experimentation and trial and error may be necessary to find the right approach for your particular setup.
Additionally, it is important to take care when removing prints from the bed to avoid damaging either the print or the bed surface. Using a flat object or removal tool, floss, or physical force can all be effective methods for removing prints, but care should be taken to avoid scratching or otherwise damaging the bed surface.
Overall, with the right approach and a bit of patience, it is possible to achieve excellent print quality while minimizing the risk of prints sticking too well to the bed.
