Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2 Plus[1]Original Prusa MK4S (Prusa Research, Prague). Sold as "Original Prusa MK4S 3D Printer" and "Original Prusa MK4S 3D Printer kit"[2][3]
Release date (announcement and actual shipping)Not documentedAnnounced and available to order on 12 August 2024, the date of Prusa's launch blog post, with assembled printers, kits and an MK4S/MMU3 bundle in stock at announcement[4]
Street price (USD; dated snapshot per entry)$999.00 on store.creality.com, Aug 2026[5]$925.00 assembled, $657.40 as a kit, on prusa3d.com, Aug 2026. Bundles: $1,171.11 with MMU3, $1,185.65 with the Enclosure, $1,438.33 with both[3][2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Largest and only fully specified K2. It is the only one with a 350 C nozzle, a 120 C bed, 30000 mm/s2 acceleration, step-servo motors on Z as well as X/Y, automatically adjusted belt tension, two auxiliary cooling fans, two air filters, a 1080p chamber camera, dual-band Wi-Fi and a 4.3-inch screen. Its "smart auto levelling" is listed as arriving via firmware update rather than shipping enabled, unlike the K2 and K2 Pro. A separate K2 SE model also exists[1]The MK4S is a revision of the MK4, not a new platform: Prusa sold a $99 upgrade kit that gives an MK4 all of the MK4S features (360-degree turbine part cooling, high-flow CHT nozzle, firmware and profile changes). Watch the published nozzle ceiling: Prusa's MK4 announcement table says 300 C, while the MK4S product page says 290 C. Related family members are the MK3.5 and MK3.9 upgrades of the MK3S+, which are not the same machine. With the MMU3 the standard (non-high-flow) nozzle is the recommended one[4][6][2]
Market position: superseded? successor announced?Not documentedStill sold in Aug 2026 as the entry point to the Nextruder line, positioned below the enclosed CORE One+ (Gen 2). Prusa also sells an MK4S-to-CORE One+ (Gen 2) conversion kit[3][2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable350 x 350 x 350 mm[1]250 x 210 x 220 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)495 x 515 x 640 mm[1]500 x 550 x 400 mm (X x Y x Z), stated without the spool holder[2]
Net weight (kg)35 kg[1]7 kg (without spool)[2]
Frame construction & materialNot documentedAluminium extrusions and frame. Prusa's MK4 announcement records that the cut-aluminium frame of the MK3S+ was replaced by a die-cast aluminium frame for the MK4 platform, which the MK4S inherits[2][6]
Enclosure: open / enclosed; panel material; door/lidEnclosed with chamber temperature control up to 60 C and two air filters[1]Open frame. The Original Prusa Enclosure is a separate add-on and raises the achievable chamber temperature to 45 C; there is no active chamber heating[2]
Passive chamber temperature reached (if enclosed; measured values preferred)60 C max chamber temperature (manufacturer figure)[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY - Creality groups the K2 series with its CoreXY flagships and quotes 600 mm/s with step-servo motors on the X and Y axes[1]Cartesian bed-slinger - Prusa's own comparison table gives "Cartesian" for the MK4S against "CoreXY" for the CORE One and CORE One L[7]
Belts (type, width, e.g. Gates?)Automatically adjusted belt tension - the K2 and K2 Pro are tensioned by hand[1]Not documented
Stepper motors (frame size, step angle, brand if known)Step-servo motors on the X, Y and Z axes and the extruder[1]0.9 degree X and Y stepper motors, which Prusa states are used to prevent vertical fine artefacts[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic 2130. The MK4 announcement is more specific: TMC2130-LA drivers on the xBuddy board[2][6]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max printing speed (manufacturer claim)[1]Not documented
Max acceleration (claimed, mm/s²)30000 mm/s2 max acceleration (manufacturer claim) - 50% above the rest of the K2 family[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive with a 0.4 mm hardened "unicorn" quick-swap nozzle[8]Nextruder, direct drive, E3D V6 compatible with an adapter; Nextruder planetary gear system with a 10:1 gearbox ratio; aluminium heatsink and all-metal filament path[2]
Gear ratio & drive gear materialNot documented10:1 planetary gearbox in the Nextruder[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedQuick-swap Prusa nozzle system with an all-metal filament path; the MK4S ships with the high-flow Prusa brass CHT 0.4 mm nozzle. Standard (non-CHT) Prusa nozzles remain usable and are the recommended choice with the MMU3[2][4]
Max nozzle temp claimed AND firmware max temp limit (both values)350 C claimed max nozzle temperature[1]290 C claimed max nozzle temperature on the MK4S product page (Prusa's MK4 announcement table gave 300 C for the MK4)[2][6]
Heater cartridge power (W)100 W rated hotend power[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]120 C max heatbed temperature (manufacturer figure)[2]
Bed surface (material, texture, coating), single/double-sidedCoated steel flex plate, heated, removable[8]Magnetic heatbed with removable double-sided PEI spring-steel sheets; smooth PEI sheet supplied[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Smart auto levelling listed as "Available via Firmware Update" rather than shipping enabled; automatic flow-rate calibration via the nozzle AI camera[1]Load-cell sensor in the toolhead - the nozzle itself is the probe. First-layer calibration and mesh bed levelling over the print area only are fully automatic, with no Live Adjust Z step[2][6]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted[8]Filament sensor fitted as standard; on the MK4 platform this is a built-in Hall sensor that also drives automatic filament loading[2][6]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designTwo auxiliary cooling fans and two air filters[1]High-performance turbine part-cooling fan with a 360-degree air-delivery duct - the headline change from the MK4, derived from work on Prusa's HT90 industrial machine. Fan RPM is monitored in firmware[2][4]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit xBuddy board with an STM32 MCU, designed, manufactured and tested in-house, plus a custom extruder breakout board for fans and thermistors[2][6]
PSU (brand, wattage, rail voltage)Not documented240 W PSU custom-made by Delta with hardware power-panic support[2]
Total rated power drawNot documentedPower consumption 80 W on PLA settings, 120 W on ABS settings (manufacturer figures)[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Creality OS, a Klipper derivative. Creality publishes the K2 firmware source as CrealityOfficial/K2_Series_Klipper on GitHub under GPL-3.0, last pushed March 2026[9][10][1]Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[11][2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch touchscreen[1]3.5-inch 65k-colour graphic screen with touch control[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touch UI with a built-in RFID reader; Creality notes the K2 Plus has no alarm sounds, which the K2 and K2 Pro do have[1]On-device colour UI with G-code preview and one-click printing; remote control and firmware updates through Prusa Connect and the Prusa mobile app[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi (2.4 and 5 GHz), RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[1]Ethernet, Wi-Fi via the ESP module delivered with the printer, USB drive for print files, plus an NFC receiver used to hand over Wi-Fi credentials from the phone app[2][7][4]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)One chamber camera at 1080p 30 fps plus the nozzle AI camera[1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSold both assembled (plug-and-print after a 10-minute self-test) and as an assembly kit[4]
Materials Support
Officially supported filament listPLA, PETG, PET, ABS, ASA, PLA-CF, PA-CF, PPA-CF[1]PLA, PETG, Flex, PVA, PC, PP, CPE, PVB; ABS, ASA, HIPS and PA only when using the Original Prusa Enclosure with the filtration add-on[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not verified directly. Creality publishes the K2-series firmware as CrealityOfficial/K2_Series_Klipper (GPL-3.0); upstream Klipper ships the verify_heater thermal-runaway check, but whether the stock configuration enables it was not checked here[9][10]The xBuddy platform carries hardware overcurrent protection that disconnects heater and heatbed power when total current exceeds 15 A, and the firmware is open-source and auditable. Prusa also shipped Thermal Model protection to the earlier MK3 line[6][11]
Certifications (UL/ETL/CE/FCC — verify, don't assume)Not documentedPrusa states the MK4S is the first consumer 3D printer to receive UL GREENGUARD certification[2]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Creality's US store states "Up to 12-Month Warranty", a 14-day return and refund window and "Lifetime Customer Support" on its printer product pages. The "up to" wording means the term is not uniform across parts[12]2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[13][2]
Spare parts availability & pricing (nozzle, hotend, plate, board, belts)Not documentedPrusa cites a perfect 30/30 print-quality score from TechRadar and a CNET "Best Printer for Quality" title; these are quoted on Prusa's own page and were not verified against the original reviews here[2]
Independently Measured Performance
Benchmark print times (source + settings)Benchy in 15 minutes 56 seconds - independently measured by Tom's Hardware, which noted visible layer lines and slightly droopy overhangs at that speed[8]Not documented
Review scores from major outlets (list outlet + score + date)Tom's Hardware rating 4.5 out of 5 in the page's structured data[8]Not documented

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
