Original Prusa MK4/S Enclosure

If you chose the option with the LED Strip and/or Advanced Filtration System we will automatically add the needed PSU for $37.99 (already included). The PSU can power both Advanced Filtration System and LED Strip at once so only one PSU will be added. All add-ons are also separately available for purchase here.

Original Prusa Enclosure is an accessory for your 3D printer that houses your Original Prusa i3 MK3S+ or MK4 and provides a stable printing environment. The Enclosure helps to reduce odors from certain materials, lowers noise, can be equipped with useful addons for increased safety and/or the possibility to run the printer in public spaces and helps with printing advanced materials due to the passive heat coming from the heatbed (prevents warping). There is enough headroom above the printer inside the enclosure to mount the MMU2S unit. Everything is included in the package, including plastic parts, so you don’t need to print anything on your own. The only exceptions are the optional LCD supports and handles (seen in some photos) and the silver PSU retainer. In case you would like to mount the display outside of the enclosure, you can simply print the LCD supports at any time. Assembly instructions are available online. A 3D printer is not a part of the package.

Main Features

High-quality Components

The frame along with the top and bottom panels are made from metal, the side panels are made from PETG plastic. The solid robust design allows several enclosures to be stacked on top of each other and secured using screws.

Print Advanced Materials

The enclosure creates a stable printing environment with increased temperatures, shields the printer from drafts and blasts of cold air and reduces the build-up of dust on moving parts. This is perfect for printing demanding high-temperature materials which are otherwise prone to warping - such as PC CF, Nylon, PP and more.

Safety Features

Install an optional lock to prevent unauthorized access to your 3D printer - ideal solution for schools, hackerspaces and other public places. An optional filtration system (HEPA filter, 99.9% efficiency) prevents the spread of ultra-fine particles (UFPS).

Upgradable and Expandable

The enclosure can be further upgraded and expanded with official add-ons (both paid and free) and it is also ready for your DIY projects. You can design your own brackets, holders and other accessories to tailor the enclosure exactly for your needs. A dedicated section will be available at Printables.com after release.

ADD-ONS (Currently offered)

Advanced Filtration System

The filtration system is useful when you print materials such as PC Blend Carbon Fiber and other materials that produce particles during printing.

White LED Strip

You can install an optional white LED strip into the enclosure to light up your 3D printer. The strip is powered by a separate PSU which will be added to your order automatically.

Mechanical Lock

A standard mechanical lock that fits in the door of the enclosure, so you can keep your 3D printer safely locked. A perfect option for schools, universities, hackerspaces and other institutions and businesses. This lock uses a standard key. However, we're also working on an electrical lock paired with an RFID reader.

BlazeCut Fire Suppression System

A self-contained tube-style fire suppression system. The system is manufactured in Europe and uses an extremely effective, clean, and safe extinguishing medium. The system operates automatically and independently of any power supply by detecting higher temperatures. Please note, that due to the shipping restrictions and costs, delivery from Prusa is available only to addresses within the EU. For the US customers it's recommended to order from our partner Printed Solid. Other countries please find your dealer here.

PSU Cable Quick-release

The enclosure is designed to allow easy removal of the printer together with the PSU. However, if you plan to remove the printer more often, you can purchase this cable quick-release connector and remove only the printer. Please note that only black PSUs from Delta are supported. If you have the silver PSU, you have to upgrade it first.

Free ADD-ONS

The enclosure is designed to be further extended with additional printed parts, electronics, cameras, and more. A number of useful 3D printed accessories can be found at Printables.com.
