How Loud Are 3D Printers? A Comprehensive Guide

3D printing has revolutionized the way we create objects. From small trinkets to complex machinery, 3D printers have made it possible to bring digital designs to life. However, one aspect that often goes unnoticed is the noise level of 3D printers. How loud are 3D printers, and how can we reduce their noise?

The noise level of 3D printers depends on several factors, such as the type of printer, the materials used, and the printing speed. Generally, most 3D printers produce a noise level ranging from 40 decibels to 55 decibels, which is similar to the sound of a normal conversation. However, some printers can produce noise levels of up to 75 decibels, which can be quite loud and disruptive.

What Determines the Loudness of 3D Printers?

The loudness of 3D printers can vary depending on several factors. In this section, we will discuss the main determinants of 3D printer loudness.

Type of Printer

The type of printer is a significant factor in determining the loudness of a 3D printer. Generally, Fused Deposition Modeling (FDM) printers tend to be louder than other types of 3D printers due to the nature of their operation. FDM printers use motors to move the print head and extruder around the build plate, which can create a lot of noise. On the other hand, Digital Light Processing (DLP) and Stereolithography (SLA) printers use light to cure liquid resin, making them quieter than FDM printers.

Printing Speed

The printing speed is another factor that can affect the loudness of a 3D printer. The faster the printer prints, the louder it will be. This is because the motors have to work harder and move faster, which can create more noise. Slower printing speeds can reduce the noise level of a 3D printer.

Material Used

The type of material used in 3D printing can also affect the loudness of a printer. For example, printing with ABS filament can be louder than printing with PLA filament. This is because ABS filament requires a higher temperature to melt, which can create more noise from the printer’s heating element. Additionally, printing with flexible materials can also create more noise due to the printer’s motors having to work harder to move the flexible material.

In conclusion, the loudness of a 3D printer can be affected by several factors, including the type of printer, printing speed, and material used. By understanding these factors, you can make informed decisions when purchasing a 3D printer and take steps to reduce the noise level of your printer.

How Loud Can 3D Printers Get?

When it comes to 3D printers, one of the most common concerns is the noise level. While some people worry that the noise from a 3D printer will disturb their family or neighbors, others are curious about the actual decibel levels of these machines. In this section, we will take a closer look at how loud 3D printers can get.

Decibel Levels of Common 3D Printers

The amount of noise produced by a 3D printer depends upon the style of printer. In general, home use 3D printers range from 15db up to 75db at approximately 1 foot away from the printer. Most 3D printers are relatively quiet, with an average decibel range of around 40db-55db. However, it’s important to note that this can vary depending on the specific model and brand.

For example, some of the quietest 3D printers on the market include the Ultimaker 2+, the Prusa i3 MK3S, and the LulzBot Mini 2. These machines typically produce noise levels of around 50db or less. On the other hand, some of the loudest 3D printers include the FlashForge Creator Pro, the Makerbot Replicator, and the Creality Ender 3. These machines can produce noise levels of up to 75db.

Comparison with Other Noisy Devices

While 3D printers can certainly produce some noise, they are not necessarily the loudest devices in your home or workspace. For example, a vacuum cleaner can produce noise levels of up to 85db, which is significantly louder than most 3D printers. Similarly, a hair dryer can produce noise levels of up to 90db, which is even louder.

That being said, it’s still important to take steps to reduce the noise produced by your 3D printer, especially if you plan to use it for extended periods of time. Some tips for reducing noise include building an enclosure around your printer, replacing or cleaning parts that are causing excess noise, and using software to adjust the speed and acceleration of your printer. By taking these steps, you can enjoy the benefits of 3D printing without disturbing your surroundings.

Tips for Reducing the Noise of Your 3D Printer

If you’re tired of the loud noises your 3D printer makes, there are a few things you can do to reduce the noise level. Here are some tips to help you get started.

Choose a Quieter Printer Model

When shopping for a 3D printer, consider the noise level as one of the factors in your decision. Some models are designed to be quieter than others. Look for printers with a low decibel rating or those that use quiet stepper motors.

Print at Slower Speeds

Printing at slower speeds can help reduce the noise level of your 3D printer. This is because the faster the printer moves, the louder the noise it makes. By slowing down the speed, you can significantly reduce the noise level without sacrificing the quality of your prints.

Use Noise-Reducing Materials

Using noise-reducing materials can also help reduce the noise level of your 3D printer. For example, you can place a rubber mat under your printer to absorb some of the vibrations that cause noise. You can also use sound-absorbing materials like acoustic foam or sound-deadening blankets to reduce the noise level.

Place the Printer in a Soundproof Enclosure

Another option is to place your 3D printer in a soundproof enclosure. This can help reduce the noise level by containing the sound within the enclosure. You can purchase a pre-made enclosure or build your own using sound-absorbing materials like acoustic foam or sound-deadening blankets.

Consider Time of Use

If none of the above options work for you, consider scheduling your 3D printing for times when the noise won’t be a problem. For example, you can schedule your prints to run overnight when you’re asleep or during the day when you’re not home. This way, the noise won’t bother you or your family.

In conclusion, there are several things you can do to reduce the noise level of your 3D printer. By choosing a quieter printer model, printing at slower speeds, using noise-reducing materials, placing the printer in a soundproof enclosure, or scheduling your prints for quieter times, you can significantly reduce the noise level and enjoy a quieter 3D printing experience.


In conclusion, the noise level of a 3D printer depends on various factors such as the type of printer, its price tag, and the materials used. The average decibel range of 3D printers is around 40db-55db, which is about as loud as regular conversations at home. However, some printers can generate noises ranging from 35 to 75 dB.

The noise produced by 3D printers is caused by motors, fans, and vibrations. FDM printers generally produce more noise than SLA resin printers due to having more motors and fans. However, SLA printers can still produce noise due to the motors used for the laser and the fans used for cooling.

To reduce the noise level of your 3D printer, you can make a few upgrades or take some basic measures. For instance, you can replace the stock fans with quieter ones, add dampeners to the motors, or use soundproofing materials. You can also place your printer in an enclosure to muffle the noise.

In summary, 3D printers are not necessarily loud, but they can produce noise that may be annoying or disruptive. With some basic upgrades or measures, you can make your printer more silent and enjoy the benefits of 3D printing without disturbing your neighbors or family members.
