There are several reasons why the first layer of filament does not adhere properly to the bed.
Too Fast Printing: The first layer should be printed slowly and controlled to adhere well to the base. The parameter to modify to solve this issue is the “First Layer Speed.”
Bed Temperature: If the bed is too cold, the filament may cool down quickly and not stick. This can be resolved by increasing the bed temperature to the recommended setting in the filament’s technical data sheet.
Changing the Print Surface: If your printer does not have a heated bed, you may need to acquire solutions such as glass sheets to enhance adhesion or use a layer of adhesive.
Calibrating the Nozzle Height: The idea is to reduce the distance between the bed and the nozzle. The most reliable approach in these cases is to level the printer again.
A print that stops halfway can be caused by several reasons.
First, check for issues with filament feeding, such as clogs or a lack of material. Ensure that the filament is properly loaded and not tangled.
Inspect the electrical connections and cables of the printer, as a disconnection or failure in the components can interrupt the process.
Verify that the printing software and the printer’s firmware are updated, as software errors can cause unexpected stops.
Look at various components of the printer, such as the PTFE tube; if it is damaged, it may stop the print.
If the printer stops due to an error, check the error message on the screen to identify the specific problem.
It is important to emphasize that if the printer stops extruding filament but continues with the printing movements, your printer may be suffering from overheating, which can lead to a blockage in the hotend due to the softening of the filament.
To avoid tangles in the filament during printing, we need to ensure that it is properly wound and stored on its spool before starting.
Keeping the filament taut is also necessary to prevent tangles in the filament.
A good series winding of the filament also helps to avoid knots during prints.
Finally, you can use 3D spool holders, which help maintain tension and prevent tangles in the filament.
Prints with gaps or missing layers can be caused by extrusion issues or poor print settings:
Adjust print settings: If we perform a print with too low a infill or with a low number of top layers, gaps may form on the upper surfaces of the model. If the gaps are between the infill and the outer surface, the problem may be insufficient overlap between the perimeter and the infill, or the print was done at too high a speed.
Extrusion problems: If the extrusion is insufficient, it may be due to clogged hotend issues or inadequate tension on the filament.
Irregular edges or warping in prints are often caused by temperature or print speed issues.
If the extruder temperature is too high, the material may become too liquid and lose definition at the edges.
On the other hand, if the print speed is too high, the printer may not have enough time to place the material accurately, resulting in irregular edges.
Another common cause is insufficient cooling; if the printer’s fan does not cool the material quickly enough, the upper layers may warp.
Additionally, make sure that the bed is level and that the first layer adheres well to avoid warping at the base of the print, which can cause problems in the upper layers.
Extruding too little or too much plastic can be due to several factors:
Adjust the extruder multiplier parameter: This parameter adjusts the amount of plastic that is extruded for each print, which will help if too much or too little filament is being extruded.
Check the diameter of the filament: Make sure that the diameter you are using for your filament matches the diameter configured in your printing software.
Ensure that the nozzle is clean and not clogged, as this could reduce the amount of plastic being extruded.
Finally, adjust the print speed or the extruder temperature to prevent the filament from being extruded too quickly.
If the printer does not detect the filament correctly, first make sure that the filament is properly loaded and correctly inserted into the extruder. Check that there are no obstructions in the filament inlet and that the filament is not broken. Check the printer’s filament sensor (if your printer has one) to make sure it is clean and working properly; in some cases, the sensor may be dirty or misaligned. If the problem persists, turn the printer off and on to reset the system. You can also try updating the printer firmware. If all else fails, consult the printer manual or contact our technical support for assistance.
Warping occurs when the corners or edges of the model lift from the bed or base during printing, resulting in warped prints. This issue is common with ABS and ASA materials.
A simple solution is to use an adhesive or bonding solution to ensure that the first layer sticks well to the bed or base.
It is also helpful to consider using a brim or raft, which are additional layers printed around or beneath the model to increase the contact surface of the print. This is especially useful for small parts.
If this does not resolve the issue, we need to ensure that our bed is properly leveled and at the appropriate temperature.

Stringing is one of the most common problems in 3D printing. This problem refers to the fine strands of filament that are left between parts of a model when the printer moves between non-printing areas. This occurs when filament continues to exit the extruder during non-printing movements. To avoid this, adjust the “retraction” setting in your printing software until the problem no longer occurs. This setting will depend on your 3D Printer
