3D Printer Enclosure: Why Do You Need One?

3D printer enclosure can provide a stable printing environment for your printer and improve your printing results. This article will introduce the advantages of 3D printer enclosure and how to build a 3D printer enclosure.

3D Printer Enclosure Advantages

Maintain a Stable Printing Environment

The enclosure helps maintain the temperature required for the printing process and reduces temperature fluctuations, thereby reducing warping problems caused by uneven shrinkage, especially when printing materials such as ABS and nylon. The enclosure reduces heat loss from the heated bed and reduces power consumption during the printing process. In addition, moisture can affect the quality of the printed filament, making it brittle or difficult to use. The enclosure provides a relatively controlled environment to reduce the impact of moisture. The enclosed design helps to prevent dust and chips, protect the stepper motor and guide rails, improve the surface quality of the printed part, and reduce the impact of airborne particles on the printing process.

Improve safety

Harmful gases are released during 3D printing. The enclosed design reduces the spread of these gases and can be equipped with an exhaust system to exhaust harmful substances out of the workspace. The enclosure can also isolate moving parts and high-temperature areas, reducing the risk of pets or children coming into contact with the 3D printer.

Reduce noise

3D printers may make loud noises when running. A good enclosure can absorb some of the sound and reduce the impact on the surrounding environment, especially for desktop printers used at home.

How to build a 3D printer enclosure

Except for FDM printers, 3D printers of other technologies almost all come with a closed enclosure. If your 3D printer does not have an enclosure, consider adding it later. There are many alternative enclosures on the forum, such as using storage boxes, protography tent, etc. Here is how to build a custom 3D printer enclosure.

Choose the right material: The material of the DIY 3D printer enclosure should be heat-resistant, stable, and safe. Common choices include transparent acrylic sheet (PMMA), which has good light transmittance but is fragile; polycarbonate (PC) board, which is heat-resistant but expensive; MDF or plywood, which is easy to process but not transparent; and aluminum profile frame + transparent panel, which has a stable structure and is suitable for industrial-grade DIY enclosures.

Design the enclosure structure: The design of the enclosure should take into account the printer size, inlet and outlet ports, ventilation and door opening. Make sure the internal space is large enough to avoid restrictions on the nozzle or moving parts; choose a front door, top door or side door for easy operation; reserve an exhaust port and install an activated carbon or HEPA filter to reduce the impact of harmful gases; and leave reasonable inlet holes for the power supply and printer controller.

Assemble the enclosure: Acrylic or PC sheets can be fixed with screws + angle brackets, or assembled with 3D printed connectors; the wooden enclosure can be spliced ​​with wood glue + screws, and a transparent panel can be used as an observation window; the aluminum profile + panel solution is assembled with T-nuts and screws, which is stable and can expand more accessories.

Additional functions: A temperature sensor can be installed to monitor the internal temperature of the enclosure, and a small heater or exhaust fan can be installed when necessary; an LED lighting strip can be added to facilitate the observation of the printing process.

Recommended Best 3D Printer Enclosure in 2025

If you don't want DIY 3D printer enclosure, there are many high-quality enclosures available on the market. Many 3D printer brands have launched closed enclosures that are compatible with their own models, such as the Creality Fireproof and Dustproof 3D Printer Enclosure. Many 3D printer enclosures on the market are similar. This 3D printer enclosure is 750×700×900mm in size and is compatible with a variety of Creality printers. While providing a constant temperature printing environment, it effectively reduces the impact of low temperature weather on the printed model and improves printing stability. It uses pure aluminum film inside and flame-retardant material outside. It can self-melt and not spread in the event of a fire, ensuring safe use. The stable iron pipe frame enhances the structural stability, has good sound insulation and dustproof effects, and enhances the user experience. In addition, the enclosure is foldable for easy storage and carrying. The front is equipped with a zipper opening for easy operation, and is equipped with a storage bag to help store tools.
