3D Print Walls Not Sticking Together! (Solved)

3D printing is a revolutionary technology that allows users to create a wide range of objects, from simple trinkets to complex mechanical parts.

However, one common issue that many 3D printer users encounter is that their printed walls are not sticking together properly.

This can lead to failed prints, wasted time and materials, and frustration. In this article, we will explore the various causes of 3D printed walls not sticking together and provide several tips and tricks for fixing the problem.

By following these steps, you can improve the adhesion between the walls of your 3D printed objects and create strong, durable prints.

How To Fix 3D Print Walls Not Sticking Together

There are several potential causes for 3D printed walls not sticking together, and several steps you can take to try to fix the issue.

Here are some possible solutions:

1. Check your printer’s bed leveling: If the bed is not level, the walls of your print may not be sticking together properly. Make sure the bed is level and properly calibrated before printing.
2. Use the correct bed surface: Different 3D printing filaments require different bed surfaces. For example, materials like PETG and ABS tend to stick well to a bed covered in blue masking tape, while materials like PLA tend to stick better to a bed covered in a 3D printing surface like BuildTak or Kapton tape. Make sure you are using the correct bed surface for your filament.
3. Increase the bed temperature: Increasing the bed temperature can help improve adhesion between the walls of your print and the bed. This is especially important for materials like PETG and ABS, which require higher bed temperatures to stick properly.
4. Use a brim or raft: Adding a brim or raft to your print can help improve adhesion between the walls and the bed. A brim is a series of concentric lines around the base of your print that can help hold it in place, while a raft is a layer of material that is printed underneath your object and helps it stick to the bed.
5. Use a cooling fan: Some 3D printers have a cooling fan that helps to cool the filament as it is extruded. If your printer has a cooling fan, try turning it off or reducing its power to see if it helps improve adhesion between the walls of your print.
6. Check your filament: Make sure you are using high-quality filament that is stored properly to prevent moisture absorption. Moisture in the filament can cause poor adhesion and other issues during printing.
7. Check your printer’s nozzle: If the nozzle is clogged or not properly calibrated, it can cause issues with adhesion between the walls of your print. Make sure the nozzle is clean and properly calibrated.

I hope these suggestions help! If you are still having issues after trying these steps, it might be helpful to consult with the manufacturer of your printer or with a 3D printing expert for further assistance.

How do you reinforce a 3D printed wall?

There are several ways you can reinforce a 3D printed wall to make it stronger:

1. Use a thicker wall thickness: One way to make a 3D printed wall stronger is to simply make it thicker. This can be done by increasing the “wall thickness” setting in your slicing software.
2. Use infill: Infill is the pattern of material that is printed inside the walls of a 3D printed object. Increasing the infill density can help make the walls of your print stronger. You can do this by increasing the “infill density” setting in your slicing software.
3. Use supports: If your print has overhangs or other features that make it difficult to print with a solid infill, you can use supports to help hold the structure in place while it is printing. Supports are typically printed in a separate material, such as PVA or HIPS, and can be removed after the print is complete.
4. Use reinforcement materials: You can also reinforce a 3D printed wall by adding reinforcement materials to it after it has been printed. For example, you can use a fiberglass or carbon fiber reinforcement material to make the wall stronger.
5. Use a stronger filament: Some filaments are naturally stronger and more durable than others. For example, nylon and PETG tend to be stronger than PLA and ABS. Using a stronger filament can help make your 3D printed walls more durable.

Final Thoughts

In conclusion, 3D printed walls not sticking together is a common issue that can be caused by a variety of factors.

These include bed leveling, the use of the wrong bed surface, insufficient bed temperature, and clogged or improperly calibrated nozzles.

By following the steps outlined in this article, you can improve the adhesion between the walls of your 3D printed objects and create strong, durable prints.

These steps include using the correct bed surface, increasing the bed temperature, using a brim or raft, using a cooling fan, using high-quality filament, and checking the printer’s nozzle.

By taking these steps and troubleshooting any issues that may arise, you can overcome this common problem and create successful 3D printed objects.
