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.

Original Prusa Enclosure is an accessory for your 3D printer that houses your Original Prusa i3 MK3S+ and 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, 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.

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)
• The basic package contains: 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.

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.
