Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K1 (store title "Creality K1 Speedy 3D Printer")[1][2]QIDI Tech i-Fast, also written iFast and "I-Fast"[3][4]
Release date (announcement and actual shipping)Not documentedNot published on the listings checked (Aug 2026)[3][4]
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]$1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[4][3]
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][5]Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[4][3]
Market position: superseded? successor announced?Not documentedDiscontinued; QIDI's current line is the Q, Plus and Max series[4][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable220 x 220 x 250 mm[1]330 x 250 x 320 mm advertised[3][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)355 x 355 x 480 mm[1]710 x 510 x 670 mm[4]
Net weight (kg)12.5 kg (Tom's Hardware measurement)[7]33 kg net[4]
Frame construction & materialNot documentedFully assembled enclosed metal-frame machine[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]Fully enclosed with a heated chamber[3][4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (Creality's own K1-series comparison table)[1]Dual independent extruders in an enclosed Cartesian gantry[3][4]
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]30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[4]
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]Direct-drive, two extruders. MK10-style nozzle[3][4]
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]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature[1]350 °C on the high-temperature extruder assembly[3][4]
Stock nozzle size & sizes included in boxNot documented0.4 mm nozzle diameter[4]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature[1]Not documented
Bed surface (material, texture, coating), single/double-sidedCoated steel flex plate, heated, removable[7]Not documented
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][8]Not documented
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; PWM hotend cooling fan[1]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)Not documented110-220 V[4]
Total rated power draw350 W rated power[1]700 W rated[4]
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[9][10][1]Not documented
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch 800x480 colour touchscreen[1]Not documented
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]Not documented
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]Wi-Fi, LAN, USB flash drive[3][4]
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]Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[4]
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[9][10]Not documented
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]Not documented
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][8][11]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.
