Product description: 3D printer - Original Prusa MK4S Enclosure Bundle - for self-assembly
The Original Prusa MK4S Enclosure Bundle is a comprehensive set consisting of a 3D printer in a self-assembly version and a factory enclosure . The device offers a build volume of 250 x 210 x 220 mm and supports filaments with a diameter of 1.75 mm. Thanks to the 360° cooling system, direct drive extruder with a 10:1 gear and High‑Flow nozzle, the printer achieves high quality at high printing speed . Equipped with a 3.5'' color LCD screen, xBuddy electronics with 32-bit STM32, and Power Panic and filament runout sensors. It communicates via WiFi, Ethernet and NFC, with support for Prusa Connect and offline work mode. The enclosure enables stable printing with technical filaments such as ABS or ASA, and the modular design allows for further expansion.
3D printer - Original Prusa MK4S Enclosure Bundle - for self-assembly.
The printer is based on a 32-bit motherboard and supports Input Shaper and Pressure Advance technologies.
Exceptional printing precision for professional and home projects
The printer offers a work area of 250 x 210 x 220 mm , which allows for the convenient implementation of complex projects such as housings, prototypes or functional models. The advanced Mesh Bed Leveling system and precise 0.9° Trinamic 2130 stepper motors in the X and Y axes guarantee high dimensional repeatability and excellent first layer adhesion. Additionally, there are thicker, 10-millimeter rods on the Z axis. Thanks to this, each print comes out exactly as designed in the slicer.
Advanced cooling system and high speed 3D printing
The cooling system based on a turbine fan and full 360° cooling eliminates the need to use supports at overhangs up to 75° , which significantly reduces filament consumption and shortens printing time. The standard installed brass Prusa Nozzle High‑Flow CHT 0.4 mm nozzle allows for fast material flow while maintaining excellent surface quality. The use of Input Shaper and Pressure Advance technologies in the printer software allows for the elimination of vibrations during printing, as well as the prediction of filament flow. Thanks to this, the device can achieve speeds even twice as fast as MK3.
Prusa Enclosure - Thermal Stability and Technical Filament Support
The set includes a complete Original Prusa Enclosure that eliminates drafts, stabilizes temperature and dampens sound , allowing you to work with demanding materials such as ABS, ASA or PC. It also supports more basic filaments - PLA, PETG and TPU - no need for a housing. You can additionally expand the housing with an optional HEPA filter, LED lighting, lock or fire protection system . Technical printing becomes safe, stable and more comfortable in all conditions.
Connectivity and software
MK4S is equipped with modern interfaces: WiFi (ESP module), Ethernet and NFC for quick connection. Remote control is done using the secure Prusa Connect platform and mobile app . For users who value privacy - there is the possibility of working completely offline . The whole thing is controlled by an ergonomic 3.5-inch color LCD screen and open-source firmware.
The MK4S is equipped with a WiFi module and an Ethernet port, allowing you to control the printer from anywhere using the Prusa Connect platform.
The Prusa MK4S has a strain gauge sensor built into the head that levels the table automatically.
