Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra S1[1]Creality K1C (product page title "K1C Carbon 3D Printer")[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[3]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)[3]$369.00 on store.creality.com, Aug 2026. Creality's comparison page shows $529 against a struck-through $559 on the same day[4][5]
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][6]The carbon-fibre-capable K1. Against the K1: all-metal hotend and a steel-tipped tri-metal "unicorn" nozzle integrated with the heatbreak instead of metal+PTFE and copper; air filter fitted instead of absent; 1080p AI camera, foreign-object detection, remote monitoring, time-lapse, build-surface detection and failure detection all standard instead of optional; a much longer filament list including PLA-CF, PA-CF and PET-CF. Build volume, footprint, speed and screen are identical to the K1, so a spec box that lists only those numbers cannot tell the two apart. A K1C Bayern Edition also exists[2][5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 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 482 mm[2]
Net weight (kg)9.37 kg net, 20.2 kg packaged[1]12.4 kg net, 16 kg gross[2]
Enclosure: open / enclosed; panel material; door/lidFully 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][6]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[5]
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)[5]
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[5][2]
Recommended/typical print speed300 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[5]
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended (manufacturer claims)[1]20000 mm/s2 max acceleration (manufacturer claim)[5]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Dual-gear direct-drive extruder[5]
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]All-metal hotend with a tri-metal "unicorn" quick-swap nozzle - a steel-tipped copper nozzle integrated with the heatbreak, replaced as a unit[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 limit120 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-sidedNot documentedPEI flexible build plate[2]
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]Hands-free auto levelling[2]
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; power-loss recovery[2]
Multi-material/multi-color capability or official upgrade pathMulticolour 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 designNot documentedDynamically balanced closed-loop part-cooling fan; dynamically balanced PWM hotend fan; activated-carbon air purifier fitted[2]
Electronics & Power
Total rated power drawNot documented350 W rated power; input 100-120 V / 200-240 V, 50/60 Hz[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 - the K1-series firmware source is published as CrealityOfficial/K1_Series_Klipper on GitHub under GPL-3.0, described by Creality as a clone of upstream Klipper. Creality also lists the printhead front cover and side-mounted spool holder as open-source parts[7][8][5]
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 with sleep mode, lighting control and input shaping; remote monitoring, time-lapse and AI failure detection are included rather than optional[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app, USB (print only)[1]Wi-Fi and USB drive; 8 GB 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][6][9]AI camera fitted as standard, 1080p, with foreign-object detection and failure detection[5]
Materials Support
Officially supported filament listPLA, PETG, TPU, ABS, ASA[1]ABS, PLA, PETG, PET, TPU, PA, ASA, PC, PLA-CF, PA-CF, PET-CF[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedNot 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[7][8]
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[10]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[11]
Independently Measured Performance
Review scores from major outlets (list outlet + score + date)Not documentedTom's Hardware rating 4.5 out of 5 in the page's structured data[12]

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.
