|---|---|---|
| Identity | ||
| Brand | Creality | Rat Rig |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K1 Max[1] | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[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] | $2,319.99 at Fabreeko for the fully-specified US kit (price includes shipping and duty in the continental USA), Batch 4, checked Aug 2026. 300 mm ABS-parts variant in stock, 400 mm down to one unit. Rat Rig's own base kit is priced separately in EUR[2][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] | Three sizes (300, 400, 500 mm cubes) and three motion configurations: Standard CoreXY, Hybrid CoreXY (+$149.99, adds two motors to Y), and IDEX with two independent toolheads (+$450.00). Superseded by the V-Core 4.1. Raspberry Pi and enclosure panels are not included[2][4] |
| Market position: superseded? successor announced? | Not documented | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables. Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 owners[4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 300 x 300 mm[1] | 300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 435 x 462 x 526 mm[1] | Not documented |
| Net weight (kg) | 18 kg (Tom's Hardware measurement)[6] | Not documented |
| Frame construction & material | Not documented | 30-series aluminium extrusion with printed ABS structural parts[2][4] |
| Enclosure: open / enclosed; panel material; door/lid | 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[1] | Open by default; enclosure panels sold separately[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (Creality's own K1-series comparison table)[1] | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | TMC2209[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 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] | LDO Orbiter 2.0 direct-drive extruder[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] | Phaetus Rapido 2.0 UHF[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | Not documented |
| 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 | Smooth PEI steel flex plate, heated[6] | Keenovo silicone bed heater[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[6][7][8] | Beacon eddy-current probe[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted[6] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Closed-loop part-cooling fan and PWM hotend fan, both annotated as changing to dynamically balanced versions; activated-carbon air filter fitted[1] | Nidec 4028 part-cooling fan[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | BigTreeTech Octopus[2] |
| Total rated power draw | 1000 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[9][10][1] | RatOS, Rat Rig's Klipper distribution[4] |
| 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 with remote monitoring, time-lapse, build-surface detection and failure detection all included[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi plus RJ45 Ethernet - the only K1-series machine with a wired network port; 8 GB storage[1] | Not documented |
| 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 print | Not documented | Self-assembly kit; Raspberry Pi and enclosure panels sourced separately[2] |
| Materials Support | ||
| Officially supported filament list | ABS, PLA, PETG, PET, TPU, PA, ASA, PC, PLA-CF, PA-CF, PET-CF[1] | Not documented |
| 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[11] | Not documented |
| 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[6] | 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.
