Original Prusa Enclosure

Introducing Original Prusa Enclosure: Modular box for your 3D printer.

Enclosures mainly help with stabilizing the inner environment and raising ambient temperatures, which is vital for printing materials such as ASA, PC-CF, PP, and others that have a tendency to warp. We also prepared a handful of add-ons that cater to any of your specific needs.

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 will be separately available in the future.

Original Prusa Enclosure is an accessory for your 3D printer that houses your Original Prusa i3 MK3S+ 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, you don’t need to print anything on your own. The only exception is the handles (seen in some photos) – these are optional and not included in the package because most users won’t need to move the enclosure around. Assembly instructions are included. 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. The frame features mounting elements for the installation of various add-ons and tidy cable management.

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 of the prusa enclosure

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. The filtration system will be also compatible with the “Smart Box” electronics, one of the future add-ons. Please note that enclosures with the Filtration System have extended lead times!

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. The LED strip is programmable, however, this functionality will become available only after the release of the Smart Box add-on.

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 being conected

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. We are preparing a number of useful 3D printed accessories for the enclosure - there will be a dedicated collection of prints at Printables.com (coming soon).

Future ADD-ONS

The following addons will be released later this year. We will share more details once they are closer to release.

Smart Box

Optional electronics that serve as an interface between the MK3S+ and various add-ons, mainly the advanced filtration system. The Smart Box will allow communication with various additional equipment, such as advanced thermal sensors, RGB LEDs, humidity meters, a microparticle sensor and also an electronic lock. All the devices can work together, so, for example, when the printer finishes a job, the RGB LEDs will signal the print is done. However, the door will remain locked and the advanced filtration system will increase the power to maximum RPM to clean the air in the chamber quickly. Once the sensors detect the conditions are optimal, the electronic lock is automatically released.

We’re currently preparing the following add-ons:

  • Smart RGB LEDs
  • Electronic lock
  • RFID reader
  • Advanced temperature sensors
  • Humidity sensor
  • Microparticle sensor

Expensive? Yes. Worth the Money? Yes. I’ve had my enclosure a few days now and can honestly say that it was well worth the money. Assembling it took a lot longer than I expected but the end result is well worth it. I’ve always had an issue with stringing and slight warping when printing PETG but I’ve printed 5 different PETG things (including brackets for the enclosure) and all 5 items had no stringing or warping issues at all. I feel the stable temp helped completely eliminate it. Also a major bonus of the enclosure is it makes the printer MUCH quieter than it used to be and there is enough room on the top of the enclosure that I was able to set my Prusa mini printer on the top and have it printing too (saves me quite a bit of space. The build quality of the enclosure is top notch and I’m not worried at all about the longevity of it. Overall I’m very happy with the purchase, I would totally recommend it, and I’m looking forward to buying the future advanced board upgrade when it’s available.

Well built and designed. Great idea. Great materials. But not suitable for models with the silver PSU until two things happen:1. The instructions are updated for silver PSU models2. A new FS cover is designed to fit the silver PSU models. Im unable to use mine as the FS cover sent and available does not match my printer. Will have to improvise until Prusa comes up with a solution.

Just too large. Ordered 12 weeks ago and just put it together, unfortunately I will not be keeping it. The enclosure itself is huge, then you add the power supply onto the backside, and the control panel onto the front side and its nearly 30" deep so it doesn't fit on any normal desks or shelves that the MK3s+ would easily fit on.
