| Property | Anycubic Kobra S1COREXY | Creality K1COREXY |
|---|---|---|
| Identity | ||
| Brand | Anycubic | Creality |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1[1] | Creality K1 (store title "Creality K1 Speedy 3D Printer")[2][3] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[4] | Not documented |
| Street price (USD; dated snapshot per entry) | $349.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $549.00 ($401.00 for the EU plug variant)[4] | $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[3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The CoreXY line, not to be confused with the gantry/bed-slinger Kobra 3, Kobra 4 and Kobra X. Within the S line the Kobra S1 Max is a much bigger machine: 350 mm cube against 250, a 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 does not have at all, and 25.7 kg against 9.37 kg. Multicolour is sold separately on both (ACE Pro / ACE 2 Pro)[1][5] | 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[2][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 250 x 250 mm[1] | 220 x 220 x 250 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 400 x 410 x 490 mm[1] | 355 x 355 x 480 mm[2] |
| Net weight (kg) | 9.37 kg net, 20.2 kg packaged[1] | 12.5 kg (Tom's Hardware measurement)[7] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed - Anycubic's own wording is "Fully Enclosed CoreXY Construction". There is no active chamber heating on the S1 (that is the S1 Max's addition)[1][5] | Enclosed 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[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (stated outright in Anycubic's specification table)[1] | CoreXY (Creality's own K1-series comparison table)[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | 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[2][6] |
| Recommended/typical print speed | 300 mm/s recommended print speed (manufacturer figure)[1] | 300 mm/s typical printing speed with 12000 mm/s2 typical acceleration, stated by Creality alongside the 600 mm/s headline[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended (manufacturer claims)[1] | 20000 mm/s2 max acceleration (manufacturer claim)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | Dual-gear direct-drive extruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-release hotend; 0.4 mm standard nozzle expandable to 0.25, 0.6 and 0.8 mm[1] | 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[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 320 C maximum nozzle temperature[1] | 300 C claimed max nozzle temperature[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C maximum hotbed temperature on a PEI spring steel build plate - the highest bed ceiling of any Anycubic machine in this file except the S1 Max[1] | 100 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Coated steel flex plate, heated, removable[7] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 auto-levelling with Z-offset, plus area levelling[1] | Automatic bed levelling (Tom's Hardware); unlike the K1 Max there is no lidar[7][8] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, filament entanglement detection and power-loss resume[1] | Filament run-out sensor fitted[7] |
| Multi-material/multi-color capability or official upgrade path | Multicolour is sold separately - the ACE Pro / ACE 2 Pro units are not included with the bare S1[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Closed-loop part-cooling fan; PWM hotend cooling fan[2] |
| Electronics & Power | ||
| Total rated power draw | Not documented | 350 W rated power[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS, with pressure advance and flow calibration supported[1] | 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][2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | 4.3-inch 800x480 colour touchscreen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus slicing software, the Anycubic app and USB (print only); AI spaghetti detection and object-skip supported[1] | 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[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app, USB (print only)[1] | Wi-Fi only - no Ethernet (the K1 Max adds RJ45); 8 GB of on-board storage[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Standard HD camera fitted, but only 480p - lower than the 720p units on the S1 Max, Kobra 4 and Kobra X[1][5][11] | AI camera optional, not fitted as standard - unlike the K1C and K1 Max, which include a 1080p camera[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU, ABS, ASA[1] | Hyper PLA, PLA, PETG, TPU, ABS - a notably shorter list than the K1C, because of the PTFE-lined hotend[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | 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] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 46 dB or less in standard mode and 44 dB or less in quiet mode - manufacturer figures with no distance or method stated, so not comparable with an independently measured reading[1] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[12] | 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[3] |
| Independently Measured Performance | ||
| Review scores from major outlets (list outlet + score + date) | Not documented | 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][13] |
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.
