3D printers can be a nuisance to you and the next room neighbors due to the noise they produce.

However, the good news is that you can improvise and reduce unwanted noise through a simple solution.

This article looks at effective solutions and techniques you can apply and eliminate your 3D printer noise. We will also answer all those questions that have bothered you for a long time. So, stick around.

Do 3D Printers Make a Lot of Noise?

Just how loud is the average 3D printer?

The average noise level of a 3D printer is 50 decibels, and it can range from 40 to 75 decibels, depending on the printer’s model.

Cheap and low-quality printers can produce noise levels up to 75 decibels, while good printers have lower noise levels to a value of 40 decibels.

You may want to know how loud the sound is when represented by a decibel value.

In simple terms, 75 decibels are equivalent to a hairdryer’s sound, while 40 decibels are equivalent to a normal conversation.

Are Resin Printers Silent?

You are probably asking this because you have heard resin printers are better for taming noise.

The answer is yes simply because they have fewer fans and motors than Fused Deposition Models (FDM), which have several stepper motors.

The sound reduction in resin printers is also efficient because they have an enclosure. They are enclosed because of protecting the photo-curing resin. That is in comparison to FDM printers which are open.

However, regardless of the type or condition of the printer, there are steps you can take to reduce noise and stop being a nuisance to your neighbors.

Why Is My 3D Printer Making Noise?

The following reasons could be responsible for the noise.

The following components generate the noise coming from your 3D printers:

Now that you know the noise source, it is easier for you to find the solution to reduce or get rid of it.

How Can I Make My 3D Printer Quieter?

To reduce the noise coming from your printer, you begin by identifying the source of the noise. For example, if the source is the fan, you fix it individually.

The following are the simple solutions you can take to fix each source and have a quiet printer.

Adjust Your 3D Printer Stepper Motor Dampers and Bolts

The adjustment involves the options detailed below:

Vibration Dampers

The stepper motor vibration dampers are installed on each stepper motor between the motor and printer frame.

The technique applies only to FDM printers since most noise comes from the fan for resin printers. The following is how it works to reduce noise:

The vibration dampers technique is effective since it deadens the noise produced by the moving components of the printer.

Consider Adjusting Stepper Motors Bolts

You should apply a standard pressure on stepper motor bolts for this method to work. Don’t overtighten or leave the bolts too loose, increasing the vibrations.

Upgrade the Printer’s Main Board to Silent Mode

Silent mainboards have modern motor drivers that reduce the noise by regulating the input current.

It will be more efficient if you change the drivers without simply replacing the whole mainboard. However, it will be far more effective to combine the two.

Adjusting the Printer Speed Will Lower Your 3D Printer Noise Levels

Lower printing speed will cause your printer to produce louder noise, and Likewise, the nozzle’s fast print speed results in higher printer sound.

It is recommended not to increase or lower the 3d printer speed as that will have a quieter printer during printing and better print quality.

Use Decoupling to Reduce Your 3D Printer Noise

Decoupling your printer from the floor will reduce loud noise by preventing amplifying and resonating of printer noise.

The best way to decouple your printer is by putting foam blocks and a concrete paver. You do this by placing a rubber mat, a thick yoga mat, or thick foam (check at Amazon) between the printer and the surface it sits on.

That will effectively absorb the sound being resonated and amplified by the floor, reducing noise.

Act to Reduce the Cooling Fan Noise

These steps will help you reduce the fans noise:

If you want to reduce the fan speed, the solution is to install larger fans that spin slowly and give you the same cooling effect.

Cheap and poor model fans may also be poorly designed, generating excess sound. You may consider replacing them with quieter fans that have a better design.

Ensure the Moving Parts Are Well Lubricated and Loose Bolts Tightened

Ensure that all the moving parts are sufficiently lubricated to prevent friction in your regular maintenance routine. You may want to check the following:

Install an Enclosure for Your Printer

Enclosures will help to absorb and dampen the noise generated by your printer. An enclosure is a box that separates the print area and the ambient air.

The separation by the enclosure absorbs the sounds coming from the print area hence getting rid of loud noise.

What Is the Best Way to Soundproof a 3D Printer?

The standard way to soundproof your 3D printer is to place it in an enclosure or cabinet. You can do that after you have made the necessary noise reduction adjustments.

Placing your printer in the cabinet can give you up to 10 decibels that can be correctly termed soundproof.

That makes it so effective that even the person in the same room cannot hear it. However, keep the following in mind as you apply this technique:

However, although we have noted you don’t need ventilation, there are steps you should take to secure the health of your 3D printer. That is because you shouldn’t expose the printer to high temperatures.

The following adjustments can give the solution to that:

Conclusion

The most crucial factor you should consider above all is quality when buying your 3D printer. Although there are options available to reduce the noise, the efficiency of the methods you apply will be dependent on the printer model.

It will be easier to achieve soundproof results with a good 3d printer than poor printers that will need a lot of fixing.
