Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K1 Max[1]Original Prusa MINI+ Semi-assembled 3D Printer[2]
Street price (USD; dated snapshot per entry)$549.00 on store.creality.com, Aug 2026. Creality's comparison page shows $799 against a struck-through $899 on the same day[3][1]$508.33 on prusa3d.com, Aug 2026[4]
Variants & sibling models — and how to tell them apart (spec-contamination risk)The large K1. Build volume 300 x 300 x 300 mm and footprint 435 x 462 x 526 mm, both much larger than the K1/K1C's 220 mm cube and 355 mm-wide body; rated power is 1000 W against 350 W; it is the only K1 with RJ45 Ethernet. Its hotend is the older metal + PTFE-tube type with a copper nozzle, annotated by Creality as "Changing to All-metal Soon" and "Copper Nozzle Changing to Steel-tipped Nozzle Integrated with Heatbreak Soon", so hotend type varies by production run - do not assume it matches the K1C[1][5]Sold semi-assembled and, historically, as a kit; also offered in an Enclosure Bundle. Distinguish from the larger i3-family machines - the MINI+ is Bowden-fed with 2209 drivers, a 280 C nozzle ceiling and a 100 C bed, all lower than the MK3S+/MK4S. Note that Prusa's own MINI+ page carries an "Awards & Press Reviews" paragraph that is entirely about the MK3S, not the MINI+[2][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable300 x 300 x 300 mm[1]180 x 180 x 180 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)435 x 462 x 526 mm[1]380 x 330 x 380 mm (X x Y x Z), stated without the spool holder and external PSU - the external PSU brick needs additional desk space[2]
Net weight (kg)18 kg (Tom's Hardware measurement)[7]4.5 kg without spool holder and external PSU[2]
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; sold with an optional Enclosure bundle[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (Creality's own K1-series comparison table)[1]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic 2209 silent stepper drivers, with sensorless homing on the X and Y axes[2]
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][5]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]Bowden extruder with 3:1 gearing - the only current Prusa FFF machine that is not direct drive[2]
Gear ratio & drive gear materialNot documented3:1 extruder gearing[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Metal hotend with a PTFE tube and a copper nozzle, both annotated by Creality as changing to all-metal and to a steel-tipped integrated nozzle "soon"[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]280 C claimed max nozzle temperature - lower than the 290-300 C of the i3-family machines[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature[1]100 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedSmooth PEI steel flex plate, heated[7]Removable magnetic steel sheets in several surface finishes; heatbed with cold-corner compensation[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic bed levelling assisted by a lidar sensor - Tom's Hardware records "Automatic + LIDAR", a feature the K1 and K1C do not have[7][8][9]SuperPINDA inductive probe with no temperature drift, driving automatic mesh bed levelling[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted[7]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designClosed-loop part-cooling fan and PWM hotend fan, both annotated as changing to dynamically balanced versions; activated-carbon air filter fitted[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit board of Prusa's Buddy family; the MINI/MINI+ is covered by the same Prusa-Firmware-Buddy source tree as the MK4, XL and CORE One. The exact board revision is not given on the product page[2][10]
Total rated power draw1000 W rated power - nearly three times the K1/K1C figure[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Creality OS, a Klipper derivative published as CrealityOfficial/K1_Series_Klipper on GitHub (GPL-3.0); the printhead front cover is listed as an open-source part[11][12][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[10][13]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch 800x480 colour touchscreen[1]2.8-inch 65k-colour graphic screen with G-code preview[2]
On-device UI capabilities (model preview, per-object controls, etc.)Colour touch UI with remote monitoring, time-lapse, build-surface detection and failure detection all included[1]On-device colour UI with G-code preview; remote print management through Prusa Connect[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi plus RJ45 Ethernet - the only K1-series machine with a wired network port; 8 GB storage[1]USB port, RJ-45 Ethernet, optional ESP Wi-Fi module (sold separately); compatible with Prusa Connect[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)1080p AI camera fitted as standard with foreign-object detection[1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSemi-assembled: Prusa ships it in a small number of pre-built sections; also historically sold as a full kit[2]
Materials Support
Officially supported filament listABS, PLA, PETG, PET, TPU, PA, ASA, PC, PLA-CF, PA-CF, PET-CF[1]PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, Woodfill and other filled materials (Prusa's own list; the 100 C bed and open frame are the practical limit for ABS/ASA)[2]
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[11][12]Three thermistors and fan RPM sensors are fitted, and the firmware is open-source and auditable (Prusa-Firmware-Buddy); Prusa does not describe the thermal-runaway implementation on the product page[2][10]
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[14]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[15][13]
Independently Measured Performance
Review scores from major outlets (list outlet + score + date)Tom's Hardware rating 4.5 out of 5 in the page's structured data[7]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.
