Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K1 (store title "Creality K1 Speedy 3D Printer")[1][2]Original Prusa MK4[3]
Release date (announcement and actual shipping)Not documentedAnnounced 29 March 2023 with assembled printers shipping immediately from stock; kits opened for ordering about two weeks later[3]
Launch MSRP (USD)Not documented1099 USD assembled, 799 USD as a kit, VAT included, at launch[3]
Street price (USD; dated snapshot per entry)$299.00 on store.creality.com, Aug 2026. Creality's own K1-series comparison page shows $389 against a struck-through $599 on the same day[2][1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Base model of the K1 family. The differences that matter are in the hotend: the K1 uses a metal + PTFE-tube hotend with a copper nozzle, while the K1C is all-metal with a steel-tipped nozzle integrated with the heatbreak and adds an air filter and a 1080p AI camera. Creality's own comparison table annotates the K1 hotend "Changing to All-metal Soon", so the hotend on a given unit depends on when it was built - check before buying. The K1 Max is the 300 mm version with 1000 W rated power and Ethernet; the K1 SE has a PA+30%GF hotend and an epoxy plate[1][4]Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD MK4-to-MK4S upgrade kit and automatically converted unshipped MK4 orders to the S version. The MK3.5 and MK3.9 upgrades convert an MK3S+ to part of the MK4 electronics stack but are not an MK4[5][3]
Market position: superseded? successor announced?Not documentedDiscontinued. No MK4 appears in Prusa's Aug 2026 3D-printer listing, and the MK4 product-page slugs redirect to the MK4S page, so no live first-party price could be recorded[6][5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable220 x 220 x 250 mm[1]250 x 210 x 220 mm (manufacturer figure)[3]
Machine footprint (mm) & clearance needed (cable/spool overhang)355 x 355 x 480 mm[1]Not documented
Net weight (kg)12.5 kg (Tom's Hardware measurement)[7]Not documented
Frame construction & materialNot documentedDie-cast aluminium frame - Prusa replaced the MK3S+'s cut-aluminium frame for the MK4, keeping only the Y-axis profiles, some bearings, the heatbed and the power supply[3]
Enclosure: open / enclosed; panel material; door/lidEnclosed with passive chamber heating only - Creality's comparison table lists "Passive Heating" for the K1, K1C and K1 Max and no chamber heating for the K1 SE[1]Open frame; the Original Prusa Enclosure is an optional add-on[3]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (Creality's own K1-series comparison table)[1]Cartesian bed-slinger of the Prusa i3 family - Prusa's MK4 announcement records that the MK3S+ Y-axis profiles and heatbed were carried over[3]
Stepper motors (frame size, step angle, brand if known)Not documented400-step (0.9 degree) stepper motors, stated by Prusa to prevent vertical fine artefacts[3]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic TMC2130-LA silent stepper drivers on the xBuddy board[3]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s max printing speed (manufacturer claim). Creality's own footnote says the 600 mm/s figure was achieved in Creality Lab and that the typical speed is 300 mm/s[1][4]Not documented
Recommended/typical print speed300 mm/s typical printing speed with 12000 mm/s2 typical acceleration, stated by Creality alongside the 600 mm/s headline[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 max acceleration (manufacturer claim)[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDual-gear direct-drive extruder[1]Nextruder direct drive with a planetary gear system, 1:10 gearbox ratio; aluminium heatsink, all-metal hotend, no PTFE tube in the filament path[3]
Gear ratio & drive gear materialNot documented1:10 planetary gearbox[3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Metal hotend with a PTFE (Teflon) tube in the filament path and a copper nozzle. Creality's own comparison table adds "(Changing to All-metal Soon)", so this is a moving target across production runs[1]Quick-swap nozzle system, 0.4 mm default, other diameters supported[3]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]300 C claimed max hotend temperature in Prusa's MK4 announcement table - note the MK4S product page publishes 290 C for the same hotend family[3][8]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature[1]120 C max heatbed temperature[3]
Bed surface (material, texture, coating), single/double-sidedCoated steel flex plate, heated, removable[7]Magnetic heatbed with removable PEI spring-steel sheets; compatible with the MK3 sheets (smooth PEI, satin, textured PEI, PA nylon)[3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic bed levelling (Tom's Hardware); unlike the K1 Max there is no lidar[7][9]Load-cell sensor: fully automatic first-layer calibration with the nozzle as the probe, plus automatic mesh bed levelling over the print area[3]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted[7]Built-in Hall-effect filament sensor supporting automatic filament loading[3]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designClosed-loop part-cooling fan; PWM hotend cooling fan[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit xBuddy board with STM32, designed and built in-house, with a separate extruder breakout board[3]
PSU (brand, wattage, rail voltage)Not documented240 W Delta PSU with hardware power panic[3]
Total rated power draw350 W rated power[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Creality OS, a Klipper derivative. Creality publishes the source as CrealityOfficial/K1_Series_Klipper on GitHub, whose own description is "clone from https://github.com/Klipper3d/klipper/", GPL-3.0, last pushed December 2025[10][11][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[12][8]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch 800x480 colour touchscreen[1]3.5-inch 65k-colour graphic screen[3]
On-device UI capabilities (model preview, per-object controls, etc.)Colour touch UI; remote monitoring, time-lapse, failure detection and build-surface detection are all optional on the K1 because they depend on the optional AI camera[1]On-device colour UI with one-click printing and status LEDs; Prusa Link is integrated and Prusa Connect adds remote printing[3]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi only - no Ethernet (the K1 Max adds RJ45); 8 GB of on-board storage[1]Ethernet built in, optional ESP Wi-Fi module delivered with the printer, USB drive; print files can also arrive over LAN or the internet via Prusa Connect[3]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)AI camera optional, not fitted as standard - unlike the K1C and K1 Max, which include a 1080p camera[1]Not documented
Materials Support
Officially supported filament listHyper PLA, PLA, PETG, TPU, ABS - a notably shorter list than the K1C, because of the PTFE-lined hotend[1]Prusa's launch table says "any thermoplastic including Nylon and Polycarbonate"; the enclosure is still needed in practice for ABS/ASA-class materials[3]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not verified directly. Creality's published firmware for the K1 series (CrealityOfficial/K1_Series_Klipper, GPL-3.0) is described by Creality itself as a clone of upstream Klipper, and upstream Klipper ships the verify_heater thermal-runaway check; whether Creality's stock printer.cfg enables it, and with what thresholds, was not checked here[10][11]xBuddy hardware overcurrent protection disconnects heater and heatbed power when total current exceeds 15 A; firmware is open-source and auditable[3][12]
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[2]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][8]
Independently Measured Performance
Review scores from major outlets (list outlet + score + date)Tom's Hardware rating 4 out of 5 in the page's structured data - the lowest of the K1 family, where the K1C and K1 Max both score 4.5[7][9][14]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.
