| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2 Pro[1] | ELEGOO Mars 5 Ultra. Elegoo's product handle is mars-5-ultra-9k-7inch-monochrome-lcd-resin-3d-printer[2][3][4] |
| Street price (USD; dated snapshot per entry) | $599.00 and $799.00 are the two variant prices listed on the Creality US store K2 Pro Combo page, Aug 2026 - the combo includes a CFS unit, so neither figure is a bare-printer price[5] | $269.00 in Elegoo's live US product feed, in stock, checked Aug 2026. The Mars 5 Series collection page rendered $259.00 against a $338.00 compare-at price on the same day, so the two Elegoo surfaces disagree by $10[4][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Between the K2 (260 mm cube, no chamber heating, 100 C bed, 8 GB) and the K2 Plus (350 mm cube, 350 C nozzle, 120 C bed, 30000 mm/s2, dual filters, auto belt tensioning, 1080p camera, dual-band Wi-Fi). The K2 Pro shares the K2's 300 C nozzle and 70 W hotend but gets the chamber heater, RFID reader, Ethernet and 32 GB storage[1] | Not a trim of the Mars 5 — a different imaging stack and a different release mechanism: 7-inch 9K LCD and 18 um pixels vs 6.6-inch 4K and 35 um, 150 vs 70 mm/h, tilt-release vs straight lift, an AI camera, and Wi-Fi added. Seven bundle SKUs pair it with Mercury Plus V2.0/V3.0 or Mercury XS at $363-$432[6][2][3][4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 300 x 300 mm[1] | 153.36 x 77.76 x 165 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 445 x 477 x 573 mm[1] | 260 x 268 x 451.5 mm[2] |
| Net weight (kg) | 23.7 kg[1] | Approximately 8.8 kg[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with chamber temperature control up to 60 C; one air filter[1] | Open-frame MSLA with a removable UV-blocking cover[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 60 C max chamber temperature (manufacturer figure)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - Creality groups the K2 series with its CoreXY flagships and quotes 600 mm/s with step-servo motors on the X and Y axes[1] | MSLA with tilt-release: the resin tank tilts after each layer to peel the part rather than pulling straight up. Single Z axis[2] |
| Belts (type, width, e.g. Gates?) | Manual belt tensioning[1] | Not documented |
| Stepper motors (frame size, step angle, brand if known) | Step-servo motors on the X and Y axes and the extruder[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s max printing speed (manufacturer claim)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | Not documented |
| Heater cartridge power (W) | 70 W rated hotend power[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heatbed temperature[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Smart auto levelling, plus automatic flow-rate calibration using a nozzle AI camera[1] | Automatic levelling, one click, via an intelligent mechanical sensor. One-Click Self-Check routine. Alarms for resin shortage, residue detection and levelling failure[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One auxiliary cooling fan and one air filter[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 V, 50/60 Hz, 24 V 3 A[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Creality OS, a Klipper derivative. Creality publishes the K2 firmware source as CrealityOfficial/K2_Series_Klipper on GitHub under GPL-3.0, last pushed March 2026[7][8][1] | Not named by Elegoo. Supported slicer is CHITUBOX[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4-inch touchscreen[1] | 4.0-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touch UI with alarm sounds and a built-in RFID reader for automatic filament identification (needs Creality RFID filament)[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi 2.4 GHz, RJ45 Ethernet, USB drive and a Creality 485 port; 32 GB eMMC[1] | USB and Wi-Fi[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | One chamber camera at 720p 30 fps, plus a separate nozzle AI camera used for flow calibration[1] | AI camera fitted; Elegoo does not publish its resolution for this model[2] |
| Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it? | Not documented | AI camera detects empty build plates and print errors[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, PET, ABS, ASA, PLA-CF, PA-CF, PPA-CF[1] | 405 nm photopolymer resin. No compatibility list published on this listing[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not verified directly. Creality publishes the K2-series firmware as CrealityOfficial/K2_Series_Klipper (GPL-3.0); upstream Klipper ships the verify_heater thermal-runaway check, but whether the stock configuration enables it was not checked here[7][8] | Not documented |
| Firmware safety limits (max temp cutoffs — exact values) | Not documented | Overheating protection activates above 80 °C[2] |
| 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 |
| Resin & MSLA | ||
| Masking LCD | Not documented | 7-inch 9K monochrome masking LCD, 8520 x 4320 px, XY pixel pitch 18 x 18 um (manufacturer specification)[2][4] |
| Light source | Not documented | 25-LED COB light source emitting a 405 nm UV beam (manufacturer specification)[2] |
| Light uniformity & intensity | Not documented | 92% light uniformity claimed by Elegoo. No intensity figure published, and no independent measurement[2] |
| Vertical print speedmm/h | Not documented | 150 mm/h maximum, which Elegoo attributes to the tilt-release mechanism (manufacturer claim). Elegoo also offers switchable slow and fast print modes but does not state the layer height the figure assumes[2] |
| Layer exposure times | Not documented | 1.5-3 s layer cure time (manufacturer figure; layer height not stated). Sortable value is the midpoint[2] |
| LCD life & replaceability | Not documented | Masking LCD protected by a scratch-resistant tempered 9H glass cover that also guards against resin leakage. Elegoo publishes no rated screen life in hours and does not state whether the user can replace the LCD[2] |
| Resin vat & feeding | Not documented | Resin tank supplied with the machine; resin-shortage and residue-detection alarms fitted. Capacity not published; no auto-refill[2] |
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.
