ClassCOREXYRESIN
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Creality K2[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)Not documented$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)Smallest of three K2 machines that share a product page. K2: 260 mm cube, no chamber heating, 100 C bed, 300 C nozzle, 8 GB storage, one air filter, one auxiliary cooling fan, 720p camera, no RFID reader, no Ethernet. K2 Pro: 300 mm cube, 60 C chamber, 110 C bed, RFID, Ethernet, 32 GB. K2 Plus: 350 mm cube, 350 C nozzle, 120 C bed, 30000 mm/s2, dual air filters, auto belt tensioning, 1080p camera, dual-band Wi-Fi. A K2 SE also exists as a separate model[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[5][2][3][4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable260 x 260 x 260 mm[1]153.36 x 77.76 x 165 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)404 x 436 x 545 mm[1]260 x 268 x 451.5 mm[2]
Net weight (kg)18.3 kg[1]Approximately 8.8 kg[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed, but with no chamber temperature control - Creality's table gives a max chamber temperature for the K2 Pro and K2 Plus and a dash for the K2. One air filter fitted[1]Open-frame MSLA with a removable UV-blocking cover[2]
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 (the K2 Plus is auto-adjusted)[1]Not documented
Stepper motors (frame size, step angle, brand if known)Step-servo motors on the X and Y axes and the extruder (the K2 Plus adds them on Z)[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 limit100 C max heatbed temperature - the lowest in the K2 family[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Smart auto levelling fitted; unlike the K2 Pro and Plus there is no nozzle AI camera, so there is no automatic flow-rate calibration[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 designOne auxiliary cooling fan and one air filter[1]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)Not documented100-240 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[6][7][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; no built-in RFID reader[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi 2.4 GHz, USB drive and a Creality 485 port; no Ethernet. 8 GB eMMC storage[1]USB and Wi-Fi[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)One chamber camera, 720p at 30 fps[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 documentedAI camera detects empty build plates and print errors[2]
Materials Support
Officially supported filament listPLA, PETG, PET, ABS, PLA-CF - a shorter list than the K2 Pro and Plus, which add ASA, PA-CF and 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[6][7]Not documented
Firmware safety limits (max temp cutoffs — exact values)Not documentedOverheating 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[8]Not documented
Resin & MSLA
Masking LCDNot documented7-inch 9K monochrome masking LCD, 8520 x 4320 px, XY pixel pitch 18 x 18 um (manufacturer specification)[2][4]
Light sourceNot documented25-LED COB light source emitting a 405 nm UV beam (manufacturer specification)[2]
Light uniformity & intensityNot documented92% light uniformity claimed by Elegoo. No intensity figure published, and no independent measurement[2]
Vertical print speedmm/hNot documented150 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 timesNot documented1.5-3 s layer cure time (manufacturer figure; layer height not stated). Sortable value is the midpoint[2]
LCD life & replaceabilityNot documentedMasking 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 & feedingNot documentedResin 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.
