After 3D printing for a while, the machine suddenly started making strange noises. What steps should I take to fix it? Most of us think it’s outdated and we need to buy another one or have it professionally fixed. will conclude. It shouldn’t be the solution because the problem can be solved by itself.
3D printer noise is a common problem, and even if you’ve never encountered it before, you might someday. This is most common in DIY FDM 3D printers and cheap printers. however, best 3d printer You may have the same problem. Below we detail the main causes of noise in 3D printers and how to fix them.
Main sources of noise in 3D printers and how to solve them
Below are some of the most common reasons for noise in your 3D printer and some tips to fix the problem.
1. The stepper motor is not set correctly
Stepper motor settings are the first major source of noise in 3D printers, as they are responsible for moving the machine. If the setting is off, noise can occur when the 3D printer tries to move other parts. To address this issue, make sure the wires are connected properly and adjust the motor properly.
Also, a motor damper can be installed to reduce noise. Dampers are made of rubber or plastic and reduce noise by absorbing motor vibrations.
2. Extruder issue
The extruder contains gears and a drive mechanism responsible for pushing the filament out of the nozzle and moving the entire extruder from one end to the other. If any of these parts are not working properly, you may hear noise. The filament path should also be inspected for obstructions and the extruder gear position and tension should be correct so that the extruder runs smoothly and the filament is extruded without problems. there is.
Also check the printhead harness to see if it is too tight or too loose as it can also affect extruder movement.
3. Z-axis wobble not adjusted correctly
If the threaded rod is bent, abnormal noise will be generated during operation, so it must be adjusted so that it moves smoothly. Also, if the Z-axis coupling becomes loose due to continued use or wear, replace it and check that it is firmly fixed.
4. Loose screws and nuts
Vibrations during printing can loosen screws and nuts over time, causing rattling noises. You should check your 3D printer regularly to make sure it is tight. Do not overtighten at this time. Other problems may occur.
5. 3D printing at lightning speed
At high speeds, stepper motors move and change direction at high speeds, which can cause a lot of vibration and noise in a 3D printer. This is even more likely if the motor driver is not tuned properly. Vibrations can also occur as the extruder moves quickly from one location to another.
Faster printing can help reduce print time, but it can also increase vibration and reduce print quality. So you should use the speed that works best for your machine. You can easily adjust the print speed with the slicer before starting the process.
6. Place the 3D printer in an uneven location
Placing the printer on an unstable table or surface will cause the printer to vibrate and make more noise. Therefore, the table on which the 3D printer rests must be stable and sturdy to avoid vibrations.
The type of material used for the table or surface on which the 3D printer will be placed should also be considered. Others, such as glass, further amplify the noise level.
7. Misaligned build plate
If the build plate is not properly balanced or positioned, it will wobble as the bed moves from one side to the other, especially when it contacts the frame. In addition, it puts strain on other components and can increase friction and noise. In addition to balancing the build plate, the print bed must be properly leveled.
8. Fan noise
Accumulation of dust, debris, or filament particles on the fan blades can interfere with smooth airflow, cause the fan to work harder, and increase the noise produced. Therefore, if you hear any unusual noises from your fan, you should clean and remove the accumulated dirt and dust. If the problem persists, consider removing it and replacing it.
9. Twisted filament
Even if the filament is one of the best filaments, if the filament is twisted, it can create resistance as the extruder pulls the filament. This can cause the extruder motor to work harder and create noise. Twisted filaments can also rub against other parts of the machine, creating additional noise. You can untwist it and push it out smoothly. This is a minor issue, but the sound it makes when pulled can be annoying.
10. Belt too tight or too loose
Belts that are too loose or too tight can cause noise during operation. If the belt is too loose, it can slip or jump over the pulleys, creating a clicking or gurgling noise.
Conversely, if it is too tight, it creates excessive friction and strain, which can cause the machine to make noise. It should be adjusted so that it is neither too tight nor too loose. In addition, belts should also be inspected for signs of wear or damage and replaced if necessary.
If your 3D printer is making more noise than usual, it’s important to investigate the cause of the problem. To do this, you can troubleshoot the issue using the 10 steps highlighted here. Often it only requires tightening a few screws or replacing parts. If the noise persists, you may need to install a soundproof enclosure around your 3D printer to dampen the noise, or purchase another machine for peace of mind.
