The Original Prusa MK4S 3D printer kit provides 5 primary control elements for printer operation and navigation including physical control elements, display interface, and touch control system.
Physical control elements
The MK4S Kit has two physical controls: a rotary knob for menu navigation and selection, and a reset button below it that acts as an emergency stop, halting all operations like a power cycle.
Display interface
The MK4S Kit uses a 3.5-inch color touchscreen (xLCD) as its main interface, showing menus, G-code thumbnails, QR codes, and print progress. It includes an injection-molded bezel, replacing the older 3D-printed version.
Touch control system
Touchscreen control must be enabled via Settings → User Interface → Touch. Once activated, it supports tapping and swiping for menu navigation, though some functions — like temperature and axis controls — still require the knob.
Touch control limitations and troubleshooting:
The MK4S Kit offers dual control via rotary knob and touchscreen, combining accessibility with precise operation.
The MK4S Kit supports 3 connectivity options including USB, Ethernet, and Wi-Fi connectivity. Files can be transferred offline via USB or remotely over a network. Wi-Fi setup is simplified with NFC — just tap a smartphone to connect, avoiding complex configurations.
For secure environments, the MK4S Kit features a removable Wi-Fi module that can be detached without impacting printer operation.
Remote control is available via Prusa Connect and the Prusa app (iOS/Android), allowing users to start prints, monitor progress, and receive notifications from anywhere.
The MK4S Kit supports direct printing from Printables.com via the app, no computer needed. It works fully online or offline, with all network features optional and no subscriptions required — ideal for both maker spaces and secure environments.
The MK4S Kit includes PrusaSlicer, an open-source slicer with 180+ pre-verified printer and material profiles, removing the need for manual calibration. Built on Slic3r, it supports third-party filaments and offers speed-optimized profiles (0.25 and 0.28 mm) to leverage the high-flow nozzle.
Beyond slicing, the MK4S Kit integrates with Prusa Connect and the Prusa app (iOS/Android) for remote control — start prints from Printables.com, track progress, and get push notifications.
Firmware updates can be installed via USB, Prusa Connect, or the Prusa app. The open-source code allows security review, and all features work without subscriptions. Network use is optional, and the removable Wi-Fi module supports secure offline operation.
The MK4S Kit features an open-frame i3-style bedslinger design with a 250 × 210 × 220 mm build volume. It measures 500 × 550 × 400 mm, weighs 7.5 kg, and has an exposed aluminum frame in Prusa’s black and orange color scheme.
The MK4S Kit uses injection-molded plastic for parts like display bezels, while brackets and other components are 3D-printed in-house by Prusa.
Full list of components:
The MK4S Kit uses a Cartesian motion system with hardened steel rods and an X-axis tensioning system for motor and belt adjustment. It features new-generation stepper motors and includes input shaper and pressure advance for precise, high print speed over 300 mm/s.
Motion system specifications:
The MK4S 3D printer kit operates at 40–50 dB, mainly from cooling fans. An enclosure lowers noise to 30–40 dB. Though it lacks a silent mode, it runs quieter than previous models, with user reports noting similar or lower noise than the MK3S in normal mode.
The MK4S 3D Printer Kit features a magnetic heated bed with removable PEI-coated steel sheets, heating up to 120 °C. It offers a 250 × 210 × 220 mm build area. The magnetic system allows easy sheet swaps and part removal. A Smooth PEI sheet is included, with Satin and Textured sheets sold separately.
The MK4S 3D printer kit uses the Nextruder from the Prusa XL, featuring a load cell for auto Z alignment and a 290 °C hotend for materials like PLA, PETG, ASA, TPU, and carbon-filled filaments. Nozzles from 0.25–0.8 mm can be swapped tool-free via two thumbscrews. A 270° cooling system allows 75° overhangs without supports.
Nextruder system features:
Filament mounts on a frame-mounted reel holder of the MK4S with a 3D-printed guide to prevent unspooling. The semi-automated loading system detects and feeds filament into the Nextruder. Stuck filament detection alerts users to feed issues. With the optional MMU3, PTFE tubes and buffers manage multi-material filament flow.
The MK4S 3D printer kit runs on a 32-bit xBuddy mainboard with an STM32 microcontroller, offering USB, Ethernet, and Wi-Fi connectivity. It includes overcurrent protection (15 A limit), power panic for print recovery, and four thermistors for hotend, heatbreak, bed, and ambient temperature monitoring.
The MK4S 3D printer kit uses a 24 V DC, 240 W power supply delivering up to 10 A, protected by an F8AH250V fuse. It’s compatible with MK3 through MK4S models and powers all components — bed, hotend, motors, and electronics — during printing.
