Not Extruding At The Start Of The Print
One common issue that 3D printer users may encounter is when the printer does not extrude filament at the start of the print. This can be frustrating and may result in failed prints. However, there are several troubleshooting steps you can take to resolve this problem.
1. Prime the Extruder: Sometimes, the extruder needs to be primed to ensure smooth filament flow. This can be done by manually pushing the filament through the extruder until it starts extruding properly.
2. Adjust Nozzle Height: Incorrect nozzle height can also cause extrusion issues. Make sure the nozzle is close enough to the bed to properly adhere the filament, but not too close that it obstructs material flow. Fine-tuning the nozzle height can greatly improve extrusion.
3. Adjust First Layer Height: Similarly, adjusting the first layer height can help improve filament flow. You can experiment with increasing or decreasing the first layer height to find the optimal setting for your printer.
4. Adjust Filament Extrusion Width: If the extrusion width is not properly calibrated, it can lead to inadequate filament flow. Check your printer settings and adjust the filament extrusion width as necessary.
5. Check for Clogged Extruder/Nozzle: A clogged extruder or nozzle can also cause extrusion issues. To address this, inspect the hobbed gear, which feeds the filament, and ensure it is free from any debris. If necessary, you can also clear the nozzle using a small diameter needle or implement the nylon cold pull method to remove any obstructions.
By following these troubleshooting steps, you can overcome the challenge of not extruding at the start of the print and improve the overall performance of your 3D printer.
| Possible Causes | Solutions |
|---|---|
| Incorrect extruder calibration or offset | - Prime the extruder - Adjust nozzle height - Adjust first layer height - Adjust filament extrusion width |
| Clogged extruder or nozzle | - Check hobbed gear - Clear nozzle if necessary |
Print Not Sticking To Bed
If you're experiencing issues with your 3D prints not sticking to the bed, don't worry! This is a common problem that can be easily resolved with a few adjustments and techniques. Let's go over some steps to improve bed adhesion and ensure successful prints.
Check Bed Leveling and Nozzle Height
Uneven or unlevel beds can cause prints to detach during the printing process. It's essential to start with a properly leveled bed. Use a leveling tool or follow your printer's specific instructions to adjust the bed until it's perfectly level. Additionally, make sure the nozzle height is set correctly. If it's too far from the bed, the print won't stick; if it's too close, it may damage the surface or cause excessive filament squishing.
Adjust First Layer Height and Extrusion Temperature
Another factor that can affect bed adhesion is the first layer height. If it's too low, the filament may not adhere properly; if it's too high, the filament may struggle to extrude. Check your printer's settings and ensure the first layer height is optimized for your specific filament and bed surface.
In addition to adjusting the first layer height, you may also need to fine-tune the extrusion temperature. Proper extrusion temperature ensures the filament is melted adequately for proper adhesion to the bed. Experiment with small adjustments to find the ideal temperature for your filament and bed combination.
Consider Bed Surface and Filament Settings
The choice of bed surface and filament settings can significantly impact print adhesion. If you're using a standard print surface like glass or PEI, ensure it is clean and free from any residue. You can also switch to specialized surfaces or coatings that offer better adhesion, such as BuildTak or WolfBite.
Additionally, check your filament settings in the slicer software. Different filaments may require specific bed and extrusion temperature settings for optimal adhesion. Adjust these settings accordingly to better match your filament's requirements.
Use Adhesives and Raft/Brim
If you're still experiencing adhesion issues, there are additional techniques you can try. Applying adhesives like glue stick or hairspray to the bed surface can provide extra grip for the filament. Make sure to apply a thin, even layer and allow it to dry before starting the print.
Another useful technique is using a raft or brim. A raft is a base layer that provides a larger surface area for the print to adhere to, especially helpful for prints with a small contact area. A brim is a thin, extended layer around the base of the print, adding stability and improving adhesion. Experiment with these features in your slicer software to see if they enhance bed adhesion.
| Common Causes of Poor Bed Adhesion | Possible Solutions |
|---|---|
| Uneven or unlevel bed | Adjust nozzle height and level the bed |
| Improper bed surface or settings for filament | Change bed surface, use adhesives, adjust bed and extrusion temperature |
| Poor first layer height | Adjust first layer height in slicer settings |
| Low extrusion temperature | Adjust extrusion temperature to ensure proper filament adhesion |
| Insufficient filament flow | Check for clogs, adjust extrusion rate, or clean nozzle |
Jammed Nozzle/Clogged Extruder
A jammed nozzle or clogged extruder can be a frustrating issue that hinders the proper feeding of filament through the nozzle, resulting in poor print quality or even halted printing processes. One common cause of these problems, especially when using PLA filament, is heat creep. Heat creep occurs when the heat generated by the extruder gradually travels up the filament, causing it to soften prematurely and leading to clogs.
When faced with a jammed nozzle or clogged extruder, several solutions can get your 3D printer up and running smoothly again:
- Manually push filament: Gently pushing the filament manually can help overcome minor blockages. This can be done by loading additional filament and guiding it through the extruder until the clog is cleared.
- Reload filament: Sometimes, reloading the filament can help dislodge any obstructions. Follow your printer's instructions to unload and reload the filament properly.
- Clear with small diameter needle: A small diameter needle can effectively remove blockages by carefully probing and dislodging any filament stuck in the nozzle. Be sure to exercise caution to avoid damaging the delicate components.
- Nylon cold pull: A nylon cold pull, also known as an atomic pull, is a technique used to remove stubborn clogs. By heating the extruder to a higher temperature, inserting nylon filament, and then performing a controlled cold retraction, the residual filament can be pulled out along with the clog.
- Disassemble extruder and nozzle: In severe cases, when all else fails, it may be necessary to disassemble the extruder and nozzle. This allows for a thorough cleaning and removal of any stubborn debris or filament remnants.
By taking these steps to address a jammed nozzle or clogged extruder, you can ensure that your 3D printer can continue producing high-quality prints and keep you in control of your creative projects.
| Problem | Solution |
|---|---|
| Difficulty in filament feeding | Manually push filament through the extruder |
| Obstructed extruder | Reload filament to dislodge any obstructions |
| Nozzle blockage | Clear the nozzle using a small diameter needle or perform a nylon cold pull |
| Persistent clogs | Disassemble the extruder and nozzle for a thorough cleaning |
Pillowing, e.g., Incomplete Top Layer Fills, Top Layer Holes/Gaps
Pillowing is a common issue encountered when 3D printing with PLA filament. It refers to incomplete top layer fills or the presence of holes and gaps in the top layer of the print. This problem occurs when the top layer cools too fast, resulting in insufficient material deposition.
To address pillowing and achieve better print quality, there are several measures you can take:
- Increase the number of top layers: By adding more top layers, you provide additional material deposition and fill in any gaps or holes in the print.
- Increase infill density: Higher infill density can help improve the structural integrity of the top layer and reduce the likelihood of pillowing.
- Lower speed for solid top layers: Slowing down the printing speed for solid top layers allows for better layer adhesion and more thorough material deposition.
Implementing these adjustments will help ensure a more complete and solid top layer, eliminating pillowing and improving the overall appearance of your prints.
| Common Solutions for Pillowing |
|---|
| Increase number of top layers |
| Increase infill density |
| Lower speed for solid top layers |
One of the common issues that you may encounter while 3D printing is a smashed first layer or a bulging effect, which is often referred to as an elephant's foot. This issue typically occurs when the bed is not level, leading to uneven pressure and extrusion during the first layer deposition.
To address this problem, there are several steps you can take:
- Level the bed: Ensuring that your printer's bed is level is crucial for achieving a proper first layer. Follow the manufacturer's instructions or use a reliable bed leveling guide to adjust the bed's alignment.
- Increase the first layer height: By slightly increasing the height of the first layer, you can reduce the chances of the filament being squished, resulting in a smashed appearance or the elephant's foot effect. Adjust the settings in your slicer software accordingly.
- Adjust the first layer extrusion rate: Fine-tuning the extrusion rate for the first layer can help prevent excessive material deposition, which contributes to the bulging effect. Experiment with slightly decreasing the extrusion rate until you achieve the desired results.
- Design a chamfer into the part: Incorporating a chamfered edge or beveled corner into your 3D model can mitigate the occurrence of an elephant's foot by allowing for smoother material flow and reducing the pressure buildup during the first layer.
Implementing these steps will help you overcome the challenges associated with a smashed first layeror a bulging effect, resulting in improved print quality and consistency.

Warping or Corner Lifting
Warping or corner lifting is a common frustration when it comes to 3D printing, especially with materials like ABS and Nylon that tend to shrink upon cooling. When the edges near the bottom of the print or the surface adjacent to the print bed are not level or flat, warping or corner lifting can occur. However, there are several steps you can take to prevent this issue and ensure successful prints.
First and foremost, make sure your print bed is level. An uneven bed can contribute to warping and corner lifting. Use a leveling tool or follow your printer's instructions to achieve a level bed before starting your print.
In addition to a level bed, consider using glues or adhesives on borosilicate glass or specialized bed surfaces like BuildTak, WolfBite, or ABS juice. These adhesives provide better adhesion, helping to keep your print securely in place during the printing process.
Using an enclosure for your 3D printer can also help control the environment and minimize temperature fluctuations. This can be particularly beneficial when working with materials that are prone to warping. By maintaining a stable temperature inside the enclosure, you can reduce the likelihood of warping and achieve more successful prints.
Lastly, it's important to design your models with warping in mind. Avoid sharp corners or thin areasthat are more susceptible to warping. Instead, consider designing "lily pads" or additional support structures in problem areas to provide extra stability and prevent warping or corner lifting.
