Not Extruding at the Start of the Print
One common issue that users may encounter is when the 3D printer fails to extrude material at the beginning of a print. This can be frustrating, but there are several potential causes and solutions to consider.
- Incorrect Extruder Calibration: If the extruder isn't calibrated properly, it may not be pushing enough filament through the nozzle. Refer to your printer's manual or online resources for instructions on how to calibrate the extruder.
- Clogged Extruder/Nozzle: A clogged extruder or nozzle can prevent the filament from flowing smoothly. To address this issue, you can try clearing the nozzle by heating it and using a small wire or needle to remove any obstructions. Be sure to follow proper safety precautions when working with a heated nozzle.
- Prime Extruder: One method to ensure smooth filament flow is to prime the extruder before starting a print. This can be done manually by manually pushing filament through the extruder until it starts to flow consistently.
- Adjust Nozzle Height: Improper nozzle height can impact extrusion. Check that the nozzle is at the correct height above the print bed. If it's too close, the filament may not be able to flow properly.
- Adjust First Layer Height: Another factor to consider is the first layer height. If the first layer is too close to the bed or too far away, it may affect extrusion. Make adjustments as needed to ensure proper first-layer adhesion.
- Adjust Filament Extrusion Width: The extrusion width settings can also impact material flow. Check your printer settings and adjust the filament extrusion width if necessary.
- Babystepping: Some 3D printers have the option to adjust the nozzle height incrementally during a print using a feature called babystepping. If available, use this feature to fine-tune the nozzle height for optimal extrusion.
- Clear Nozzle: Regular maintenance and cleaning of the nozzle can help prevent clogs. Refer to your printer's manual for instructions on how to clean the nozzle or follow online resources for guidance.

Print Not Sticking to Bed
One of the frustrating issues that you may encounter during 3D printing is when the print does not adhere properly to the printer bed. However, there are several potential causes for this problem, including an unlevel bed or incorrect nozzle calibration/offset.
To ensure successful bed adhesion, there are several troubleshooting steps you can take. One of the first things to check is the level of the bed. If the bed is not level, it can lead to uneven prints and poor adhesion. Using a leveling tool or manually adjusting the bed can help resolve this issue.
Another factor to consider is the nozzle calibration or offset. If the nozzle is too far or too close to the bed, it can affect the print's adhesion. Adjusting the nozzle height according to the manufacturer's guidelines can help improve bed adhesion.
Additionally, the surface of the bed plays a crucial role in print adhesion. Changing the bed surface to one that enhances adhesion, such as a glass or adhesive sheet, can significantly improve the print's stickiness to the bed.
If adjusting the bed level and nozzle calibration/offset, as well as changing the bed surface, do not resolve the issue, you can try using adhesives specifically designed for 3D printing. These adhesives, such as hairspray or glue sticks, can provide extra grip between the print and the bed surface.
Lastly, consider adjusting the bed temperature. Different filaments require different bed temperatures for optimal adhesion. Experimenting with different bed temperatures within the manufacturer's recommended range can help improve bed adhesion.
To summarize, if you are experiencing issues with prints not sticking to the bed, check the levelness of the bed, adjust the nozzle height, consider changing the bed surface or using adhesives, and experiment with the bed temperature. These troubleshooting steps should help improve bed adhesion and ensure successful 3D prints.
Quick Tips:
- Ensure the bed is level to promote proper bed adhesion.
- Check and adjust the nozzle height for the correct calibration/offset.
- Consider changing the bed surface to enhance adhesion.
- Use adhesives specifically designed for 3D printing, if needed.
- Experiment with different bed temperatures to find the optimal setting.
Jammed Nozzle/Clogged Extruder
A jammed nozzle or clogged extruder can be a frustrating issue that disrupts the filament flow during your 3D printing process. Several factors can lead to this problem, such as heat creep for PLA or particles/carbonized filament blocking the nozzle. Fortunately, there are several solutions to help you overcome this setback.
To begin, you can try clearing the nozzle to remove any debris or blockages obstructing the filament flow. This can be accomplished by using a small brush or needle to carefully clean out the nozzle.
In some cases, manually pushing the filament through the extruder can help alleviate the jam. You can manually push the filament through by using the controls on your 3D printer. This action can dislodge any stuck or trapped filament, allowing for a smoother printing process.
If clearing the nozzle and manually pushing the filament does not resolve the issue, another option is to reload the filament. This involves unloading the current filament and reloading a fresh spool. Make sure to follow your printer's instructions for filament reload to ensure proper installation.
For more stubborn clogs or recurring issues, a nylon cold pull can help dislodge any trapped filament within the nozzle. This technique involves using a piece of nylon filament to simulate a printing process, which helps remove any debris from the nozzle.
In extreme cases, it may be necessary to disassemble the extruder and nozzle for a more thorough cleaning. This process allows you to inspect each component closely and remove any accumulated filament or blockages. However, it's important to exercise caution and follow manufacturer guidelines when disassembling your printer to avoid causing further damage.
Pillowing and Smashed First Layer (Elephant's Foot)
When 3D printing, encountering pillowing and a smashed first layer can be frustrating. Pillowing refers to incomplete top layer fills and top layer holes/gaps, while a smashed first layer results in a bulging appearance. Fortunately, there are several solutions to address these issues and achieve better print quality.
1. Increase the number of top layers
Increasing the number of top layers can help overcome pillowing. By adding more top layers, you ensure a more solid and complete finish to the top surface of the print.
2. Increase infill density
Infill density plays a crucial role in creating a solid structure for the print. By increasing the infill density, you provide more material for the top layers, minimizing the chances of pillowing.
3. Lower speed for solid top layers
Printing solid top layers at a lower speed can reduce the likelihood of pillowing. Slowing down the printer allows for better deposition of the material, resulting in a more even and solid top layer.
4. Adjust the first layer height
By adjusting the first layer height, you can optimize the adhesion between the print and the build plate. This can help prevent a smashed first layer and reduce bulging throughout the print.
5. Adjust the first layer extrusion rate
Tweaking the first layer extrusion rate can also contribute to solving the issue of a smashed first layer. Finding the optimal extrusion rate ensures a consistent and smooth first layer, reducing bulging and improving overall print quality.
By implementing these solutions, you can effectively address pillowing and a smashed first layer, achieving better print results and enhancing the overall quality of your 3D prints.
| Issue | Solution |
|---|---|
| Pillowing (Incomplete top layer fills, top layer holes/gaps) |
Increase the number of top layers Increase infill density Lower speed for solid top layers |
| Smashed first layer (Bulging first layer) |
Adjust first layer height Adjust the first layer extrusion rate |
Warping and Layer Separation
Warping and layer separation are common problems that can occur during 3D printing. These issues can be frustrating, leading to unsuccessful prints and wasted materials. However, understanding the causes and implementing the right solutions can help you overcome these challenges and achieve high-quality prints.
The Causes of Warping and Layer Separation
Several factors can contribute to warping and layer separation:
- The print temperature is set too low: If the print temperature is too low, the layers may not adhere properly, leading to warping and layer separation.
- Too much layer cooling: Excessive cooling between layers can cause the printed object to contract and warp.
- High ambient air temperature: Printing in a hot environment can increase the chances of warping and layer separation.
- The printer is printing too fast: Printing at high speeds can create issues with layer adhesion and result in warping and layer separation.
Effective Solutions to Address Warping and Layer Separation
To prevent or mitigate warping and layer separation, consider implementing the following solutions:
- Adjust the print temperature: Find the optimal temperature for your filament and adjust the print temperature accordingly. This will promote better layer adhesion and reduce the chances of warping.
- Disable layer cooling: If excessive layer cooling is causing warping, try disabling the layer cooling fan or reducing its intensity.
- Use an enclosure: Creating a controlled printing environment with an enclosure can help maintain a stable temperature and reduce the impact of ambient air temperature on the print.
- Level the bed: Ensure that your print bed is properly leveled to provide a consistent and uniform print surface.
- Use glue/adhesives: Applying a thin layer of glue or adhesive on the print bed can improve adhesion and reduce the risk of warping and layer separation.
| Problem | Cause | Solution |
|---|---|---|
| Warping | Low print temperature Excessive layer cooling High ambient air temperature Printing too fast adjust |
t print temperature Disable layer cooling Use an enclosure Reduce printing speed |
| r Separation | Low print temperature Excessive layer cooling High ambient air temperature Printing too fast adjust |
t print temperature Disable layer cooling Use an enclosure Reduce printing speed |
By implementing these solutions and optimizing your printing settings, you can minimize the occurrence of warping and layer separation, resulting in successful 3D prints with improved print quality and structural integrity.
Stringing and Blobs/ Zits on the Surface
Stringing, also known as hairy prints, can be a frustrating issue when small strings of plastic are left behind by the nozzle. These unwanted strings can negatively impact the appearance and quality of your 3D prints. Another common problem that you may encounter is the presence of blobs and zits on the surface of the print, further compromising its finish.
These issues can be caused by a combination of factors, including slow extruder movement, incorrect retraction settings, printing with PET filament, or improper extruder temperature. When the extruder moves too slowly, it allows the filament to continue flowing after it should have stopped, resulting in those pesky strings. On the other hand, incorrect retraction settings can cause the extruder to pull back too little or too much filament, leading to blobs and zits on the surface of the print.
To overcome stringing and the presence of blobs/zits, there are a few steps you can take:
- Adjust the retraction settings: Retraction plays a crucial role in preventing stringing. Increase the retraction distance to help pull the filament back when the extruder is not actively extruding. Similarly, increase the retraction speed so that the filament retracts quickly, reducing the chances of stringing.
- Adjust the extruder temperature: Experiment with adjusting the extruder temperature to find the optimal setting for your specific filament. Higher temperatures can sometimes contribute to stringing, so lowering the temperature slightly might help mitigate the issue.
- Try printing with different filaments: Different filaments have different properties that can affect stringing and the presence of blobs/zits. Consider experimenting with different filaments, such as those with improved stringing resistance or different compositions.
Example:
"I was experiencing significant stringing and noticeable blobs on the surface of my prints. After some research, I adjusted the retraction settings on my 3D printer, increasing the retraction distance and speed. Additionally, I slightly lowered the extruder temperature. These changes made a noticeable difference in reducing stringing and the presence of blobs on my prints." - John, 3D printing enthusiast
By following these suggestions and making the necessary adjustments to your retraction settings, extruder temperature, and filament selection, you can significantly minimize stringing and blobs/zits on the surface of your 3D prints, resulting in cleaner and more professional-looking output.
| Problem | Cause | Solution |
|---|---|---|
| Stringing | Slow extruder movement | Adjust retraction settings: Increase distance and speed |
| Blobs/Zits on the surface | Incorrect retraction settings adjust | t retraction settings: Increase distance and speed |
| Blobs/Zits on the surface printing | g with PET filament | Experiment with different filaments with improved stringing resistance |
| Blobs/Zits on the surface | Incorrect extruder temperature adjust | t extruder temperature: Slightly lower the temperature |
Keep in mind that solving the issue of stringing and blobs/zits may require some trial and error, as each 3D printer and filament combination can produce different results. With patience and persistence, you can fine-tune the settings and achieve high-quality prints with minimal stringing and surface imperfections.
