Enclosures help with stabilizing the inner environment and raising ambient temperatures, shields the printer from drafts and blasts of cold air, and reduces the build-up of dust on moving parts. This is vital for printing materials such as ASA, PCCF, PP, and others that have a tendency to warp.

Check our step-by-step assembly instructions for the Original Prusa Enclosure.

Also, some of these materials might produce unwanted odors during printing and the enclosure helps to contain them.

The Original Prusa Enclosure is an accessory for your 3D printer that houses your Original Prusa i3 MK3S+ and provides a stable printing environment.

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.

There is enough room above the printer’s frame for the installation of the MMU2S. You can place the spool of filament inside the enclosure and lead the strand of filament to the extruder through a PTFE tube, essentially a reverse-Bowden setup, which also helps to even out the rotation of the spool, resulting in a smoother feed of filament into the extruder.

Add-ons

Optional features can be purchased with the Enclosure or purchased later to be added.

Lock

Install an optional lock to prevent unauthorized access to your 3D printer - an ideal solution for schools, hackerspaces, and other public places. This lock uses a standard key.

Advanced filtration system

HEPA filter with 99.9% efficiency, prevents the spread of ultra-fine particles (UFPS).

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!

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 US customers it's recommended to order from our partner Printed Solid. For 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.

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.

Technical parameters

  • Dimensions with the LCD mounted outside: 530 mm (w) × 545 mm (h) × 715 mm (d).
  • Dimensions with the LCD inside: 530 mm (w) × 545 mm (h) × 640 mm (d) At least 250 mm is required in front of the enclosure for the doors to fully open.
  • Enclosure type: Passive, heating provided only by the 3D printer’s heatbed.
  • Weight: 10,6 kg (23.4 lbs).
  • Max stackable units: up to 5 (with more than 3 enclosures, anchoring to a wall is recommended).
  • Basic package: All components required to build the enclosure (frame parts, transparent side panels, top and bottom panels, mounting material, printer frame brace), temperature sensor, and documentation. Handles and optional 3D-printed accessories seen in some photos are not included in the package.
