3D printing can encounter a variety of problems that affect print quality and success rate. In the previous article, we talked about 1-5 most common problems and their potential solutions. Here are 6-10 most common problems and their potential solutions.
6. Over-extrusion
Problem: Extruding too much filament, resulting in spots and overfilled layers.
Solution:
Reduce the extrusion multiplier or flow rate in the slicing software.
Check the filament diameter setting and make sure it matches the actual filament.
Calibrate the extruder steps per millimeter (steps/mm).
7. The print is not sticking to the bed
Problem: The print detaches from the build platform during the process.
Solution:
Make sure the bed is level and clean.
Adjust the initial layer height to get closer to the bed.
Use a suitable adhesive or a different build surface.
Use raft or edge printing to improve bed adhesion.
8. Nozzle blockage
Problem: Filament cannot flow through the nozzle due to blockage.
Solution:
Heat the nozzle and manually push the filament to clear minor blockages.
Use a cleaning filament or needle to clear more stubborn clogs.
Clean and maintain the nozzle regularly to prevent clogging.
9. Inconsistent extrusion
Problem: The filament flow varies, causing gaps or irregular layers.
Solution:
Ensure consistent filament diameter and quality.
Check if the extruder gears are slipping or if the filament is grinding.
Adjust the extruder tension to ensure proper grip on the filament.
Calibrate the extruder steps per millimeter (steps/mm).
10. Z-axis wobble
Problem: Horizontal lines or waves are visible on the sides of the print due to an unstable Z-axis.
Solution:
Tighten the Z-axis lead screw and make sure it is straight.
Check if the Z-axis coupler is loose and secure it.
Use an anti-wobble mechanism or bracket if applicable to your printer model.
If you order a 3D print on our website, we will print the best prints and check the prints before shipping to avoid any of the above problems.
