| Property | Creality K1 SECOREXY | QIDI i-FastIDEX |
|---|---|---|
| Identity | ||
| Brand | Creality | QIDI |
| Class | COREXY | IDEX |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K1 SE[1] | QIDI Tech i-Fast, also written iFast and "I-Fast"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published on the listings checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | Creality's K1-series comparison page lists $359 for the K1 SE (Aug 2026); it does not appear as its own product on the Creality US store printer sitemap, so no separate live store price could be recorded[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[3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The cheapest K1. It keeps the 220 mm cube volume, CoreXY frame and 600 mm/s claim but drops a lot: hotend body is PA+30%GF rather than all-metal, the build plate is epoxy rather than PEI, there is no air filter, no chamber heating entry at all in Creality's table, no foreign-object or failure detection, and the AI camera, remote monitoring and time-lapse are optional. Its filament list stops at Hyper PLA, PLA, PETG and TPU. It does get the steel-tipped nozzle integrated with the heatbreak and dynamically balanced fans, which the base K1 does not[1] | 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[3][2] |
| Market position: superseded? successor announced? | Not documented | Discontinued; QIDI's current line is the Q, Plus and Max series[3][4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 220 x 220 x 250 mm[1] | 330 x 250 x 320 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 355 x 355 x 482 mm[1] | 710 x 510 x 670 mm[3] |
| Net weight (kg) | Not documented | 33 kg net[3] |
| Frame construction & material | Not documented | Fully assembled enclosed metal-frame machine[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed body, but Creality's comparison table leaves chamber heating blank for the K1 SE where the K1, K1C and K1 Max are listed as passive heating[1] | Fully enclosed with a heated chamber[2][3] |
| 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[2][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][5] | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[3] |
| Recommended/typical print speed | 300 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 name | Dual-gear direct-drive extruder[1] | Direct-drive, two extruders. MK10-style nozzle[2][3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Hotend body in PA+30% glass fibre with a steel-tipped nozzle integrated with the heatbreak - not the all-metal assembly of the K1C[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[2][3] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm nozzle diameter[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Epoxy flexible build plate - different from the PEI plate on the K1C[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Dynamically balanced closed-loop part-cooling fan and dynamically balanced PWM hotend fan; no air filter[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 110-220 V[3] |
| Total rated power draw | 350 W rated power[1] | 700 W rated[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Open-source Creality OS, a Klipper derivative (CrealityOfficial/K1_Series_Klipper on GitHub, GPL-3.0)[6][7][1] | Not documented |
| Connectivity, UI & Camera | ||
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; remote monitoring and time-lapse are optional because they require the optional AI camera[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi[1] | Wi-Fi, LAN, USB flash drive[2][3] |
| Materials Support | ||
| Officially supported filament list | Hyper PLA, PLA, PETG, TPU only[1] | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[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[6][7] | 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[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.
