Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality Ender-3 V3 KE[1]Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[2]
Street price (USD; dated snapshot per entry)$259.00 on store.creality.com, Aug 2026; Creality's own product page shows $279.00 on the same day[3][1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Sits between the SE and the V3 in the Ender-3 V3 family. Against the SE: linear rail on X instead of wheels, 500 mm/s instead of 250, 300 C ceramic hotend instead of 260 C, 4.3-inch touchscreen instead of a 3.2-inch knob screen, Wi-Fi instead of SD-card only. Against the V3: the KE keeps the conventional bed-slinger layout while the V3 is CoreXZ and reaches 600 mm/s. Build volume also differs subtly - 220 x 220 x 240 mm on the KE against 220 x 220 x 250 mm on the SE and V3[1][4][5][6]Three sizes, all at the same base-kit price. Acceleration is the size-dependent figure and the one most often mis-quoted: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm. IDEX is a configuration option and changes the usable area per toolhead (copy mode 150x150x300 at the 300 size, mirror mode 95x95x300). Base kit excludes electronics. Rat Rig prices the base kit only in EUR (EUR 873.90 on sale from EUR 971.00, Aug 2026); no USD list price is published, so no USD street price is recorded here[2]
Market position: superseded? successor announced?Not documentedCurrent revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable220 x 220 x 240 mm - 10 mm shorter than the SE and V3, a difference that is easy to miss[4]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]
Machine footprint (mm) & clearance needed (cable/spool overhang)433 x 366 x 490 mm (Tom's Hardware)[4]623.2 x 583 x 785 mm (300); 723.2 x 683 x 885 mm (400); 823.2 x 783 x 985 mm (500). Sortable value is the 300 mm kit[2]
Net weight (kg)7.8 kg[4]Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[2]
Frame construction & materialNot documented30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame in the base kit[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger with a linear rail on X[1]CoreXY; Hybrid CoreXY and IDEX are configuration options[2]
X-axis guide type (rods / linear rails / V-wheels; size)Steel linear rail on the X axis with a ball-bearing carriage; Creality Lab quotes a 0.04 friction coefficient[1]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s max printing speed (manufacturer claim, Creality Lab)[1]Not documented
Max acceleration (claimed, mm/s²)Not documentedSize-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[2]
Extruder
Type (direct drive / bowden) & design nameDirect-drive extruder paired with the ceramic-heated high-flow hotend[1]Full-metal skeleton toolhead, new in the 4.1[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hotend with a 60 W ceramic heater, a bi-metal copper/titanium-alloy heatbreak to resist thermal creep, and a copper nozzle[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C claimed max nozzle temperature (Creality Lab test at 25 C room temperature)[1]350 °C maximum nozzle temperature (manufacturer claim)[2]
Heater cartridge power (W)60 W ceramic heater cartridge (manufacturer figure)[1]Not documented
Stock nozzle size & sizes included in boxNot documented0.4 mm hardened steel and 0.6 mm included[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[2]
Bed surface (material, texture, coating), single/double-sidedPEI-coated spring steel sheet, heated, removable[4]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)One-tap self-test covering Z offset and auto levelling; Tom's Hardware records automatic levelling with automatic Z as well[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted[4]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designTwo part-cooling fans, one on each side of the printhead, cooling the freshly printed section from both sides[1]Improved part cooling, listed by Rat Rig as one of the 4.1 changes[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Creality OS, which Creality states is "Based on the popular Klipper firmware", with open-source files published; the source is on GitHub as CrealityOfficial/Ender-3_V3_KE_Klipper, described as a clone of upstream Klipper, GPL-3.0. Input shaping and motion advance (pressure advance) are exposed as features[1][7][8]RatOS 2.1 (Rat Rig's Klipper distribution)[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch touchscreen[4]Not documented
On-device UI capabilities (model preview, per-object controls, etc.)Touch UI with a tab bar, real-time model preview, motion graphics for print parameters and a one-tap self-test[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi and USB; LAN printing and cloud printing through Creality Print on PC or the Creality Cloud app, with multi-printer print-farm management[4][1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[2]
Materials Support
Officially supported filament listHyper PLA, PLA, PETG, ABS, TPU (95A) and ASA[1]PLA, PETG, ABS, ASA, TPU, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not verified directly. Creality states the Ender-3 V3 KE runs a Klipper-based Creality OS and publishes CrealityOfficial/Ender-3_V3_KE_Klipper (GPL-3.0) as a clone of upstream Klipper, which ships the verify_heater thermal-runaway check; the stock configuration was not checked here[7][8][1]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[9]Not documented
Independently Measured Performance
Benchmark print times (source + settings)Benchy in 19 minutes 48 seconds under Speed Boat Rules in ordinary grey PLA - independently measured by Tom's Hardware[4]Not documented
Review scores from major outlets (list outlet + score + date)Tom's Hardware rating 4.5 out of 5 in the page's structured data[4]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.
