3D printing technology has revolutionized the manufacturing sector, enabling people to create complex and intricate models with ease. However, as with any technology, it comes with its fair share of challenges. One of the most common issues users experience is beginning with the first layer. There are several 3D printing first layer issues that can occur during printing, but with some basic understanding of the process, they can be easily solved.
Have you ever seen your first layer come out uneven, causing your print to be disfigured or detached from the bed? This is a common issue called adhesion failure, which occurs due to improper bed leveling or nozzle height adjustment. You can solve this problem by re-leveling the bed or adjusting the nozzle height to ensure that the distance between the hotend and the bed is optimal.
Another common issue is under-extrusion, which results in poorly melted filament that cannot stick to the bed. In this case, the solution lies in cleaning the nozzle to remove any clogs, adjusting the cooling fan speed, increasing the temperature, or changing the filament type to one with a lower melting point to ensure proper melting and consistent extrusion.
These are just a few of the 10 common 3D printing first layer issues and solutions. If you want to learn more about these issues and how to fix them to achieve perfect prints, read on for a comprehensive guide on how to troubleshoot your 3D printing process from the first layer up to the finishing touches.

3D printing has revolutionized many manufacturing and prototyping industries by enabling the printing of complex shapes and geometries. However, one of the most common issues that many makers encounter while 3D printing is the first layer issue. In this article, we have compiled and discussed ten of the most common 3D printing first layer issues and their possible solutions.
Warped First Layer
One of the most common 3D printing first layer issues is a warped print bed. This could be due to several reasons such as an uneven bed, incorrect leveling, or an inadequate adhesive for the filament. To resolve this, ensure that the bed is clean, leveled correctly, and using some form of adhesive (such as hairspray or blue tape) to facilitate better adhesion.
If the extruder nozzle gets clogged, it can lead to a failed first layer. The reasons behind the clogs could be the use of low-quality filament, incorrect temperature settings, or a dirty nozzle. Clearing the extruder and nozzle will usually involve heating the printer to its melting temperature, removing the filament, and cleaning the nozzle.
If the extruder is not pushing out filament evenly, there will be gaps or raised areas in the first layer. This issue could result from a misaligned extruder or obstructed filament. Realigning the extruder and cleaning the filament path can help solve this issue.
Poor Bed Adhesion
Poor bed adhesion can cause the filament to detach from the print bed, which usually occurs when the bed is not adequately leveled or cleaned. Using an adhesive such as hairspray or blue tape can significantly improve bed adhesion. Further, ensure the bed is clean before starting a print job.
Print Bed Temperature Issues
The print bed temperature needs to be optimized for the filament being used. Using the correct temperature settings can have a significant impact on the quality of the first layer. Prints may fail to stick if the bed is too cool, while excessive print bed temperature can cause the filament to warp. Each filament has its recommended bed temperature so adhere to the manufacturer’s recommendations.
Filament Diameter Variations
The diameter of the filament used plays a significant role in achieving successful 3D prints. It is essential to use filament with a consistent diameter, as variations in diameter can cause under-extrusion or over-extrusion issues. As such, always measure your filament diameter before printing; this will allow you to adjust printer settings accordingly.
Inconsistent Filament Extrusion
Inconsistent extrusion of filament is one of the most common issues experienced when 3D printing. This could be due to several things, including dust or small debris being caught in the extruder, filament tension or a worn-out extruder gear. Disassembling and cleaning the extruder, and checking the filament path, can help rectify this issue.
Print Head Calibration
If the print head is not calibrated correctly, it can lead to various issues, including poor bed levelling, incorrect filament extrusion and even jams. Proper calibration improves print accuracy and prevents issues with the first layer. Calibrating the print head involves adjusting printer settings such as Z-offset to get the correct print bed height.
A blocked nozzle will prevent filament from extruding correctly, leading to issues with the first layer. To fix a blocked nozzle, you must dismantle and clean the nozzle by using specific solvents and tools designed for this purpose. You can also use a cold pull method, where heated filament is forced through the nozzle and then left to cool, resulting in any debris being pulled out as the filament is extracted.
Inadequate Bed Levelling
Incorrect bed leveling is one of the most common causes of failed first layers. If the bed is too close to the nozzle, the filament will have nowhere to go, causing obstructions, whereas if the bed is too far away from the nozzle, the filament will not be able to stick to it properly. Therefore, ensuring adequate and consistent bed leveling is essential for preventing first layer issues.
Overall, resolving 3D printing first layer issues is essential for achieving successful prints. By identifying the causes of these issues and applying the appropriate solutions, you can significantly improve your printing quality. In summary, ensure proper bed leveling and cleaning, maintain accurate printer calibration and temperature controls, and regularly clean and maintain the printer’s extruder and nozzle to achieve optimal print outcomes.

When it comes to 3D printing, the first layer is crucial for the success of the print. Here are 10 common first layer issues and their solutions:
Why is my first layer not sticking?
There could be several reasons why your first layer is not sticking, such as a dirty print bed or incorrect bed leveling. Try cleaning the print bed with isopropyl alcohol and re-leveling the bed.
Why is my first layer too thin or too thick?
This could be due to incorrect bed leveling, incorrect nozzle height, or incorrect extruder temperature. Make sure to level the bed properly and adjust the nozzle height and temperature accordingly.
Why is my first layer uneven?
An uneven first layer can be caused by an uneven print bed, incorrect bed leveling, or a warped print bed. Try re-leveling the bed and using a different print surface if necessary.
Why is my first layer shifting?
If your first layer is shifting, it could be due to a loose belt or pulley, incorrect bed leveling, or incorrect print speed. Check to make sure all of the printer components are properly tightened and adjust the bed leveling and print speed as needed.
Why is my first layer stringy?
If your first layer is stringy, it could be due to incorrect extruder temperature or incorrect retraction settings. Adjust the temperature and retraction settings as needed to reduce stringing.
Why is my first layer not solid?
If your first layer is not solid, it could be due to incorrect extruder temperature, incorrect flow rate, or incorrect print speed. Adjust these settings as needed to achieve a solid first layer.
Why is my first layer warped?
A warped first layer can be caused by incorrect bed leveling, a warped print bed, or incorrect nozzle height. Try re-leveling the bed and using a different print surface if necessary.
Why is my first layer bubbling?
If your first layer is bubbling, it could be due to incorrect extruder temperature or incorrect bed temperature. Adjust these settings as needed to prevent bubbling.
Why is my first layer over-extruded?
If your first layer is over-extruded, it could be due to incorrect flow rate or incorrect nozzle height. Adjust these settings as needed to reduce over-extrusion.
Why is my first layer under-extruded?
If your first layer is under-extruded, it could be due to a clogged nozzle or incorrect flow rate. Clean the nozzle and adjust the flow rate as needed to reduce under-extrusion.
