| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra X (store variant title "Kobra X (4 Colors)")[1] | Elegoo Saturn 4 Ultra 16K. Elegoo's product handle is saturn-4-ultra-16k-10inch-monochrome-lcd-resin-3d-printer. 3DJake item number ELG-50.101.038300[2][3] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 25 December 2025 (Shopify publish date)[4] | Not documented |
| Street price (USD; dated snapshot per entry) | $299.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $399.00 ($344.00 for the EU plug variant). The collection page headline reads "Kobra X - Price from $289"[4][5] | $649.99 in us.elegoo.com's live Shopify product JSON, in stock, with compare_at_price also $649.99 — no discount active at the time of checking (Aug 2026)[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Same 260 mm cube and the same machine dimensions as the Kobra 4 (455.4 x 445.3 x 461.3 mm) - the difference is that the Kobra X has native 4-colour printing built in, expandable to 19 colours, where the Kobra 4 needs an ACE 2 Pro for any multicolour at all. The Kobra X also takes a wider filament list (adds PVA, PLA-CF, PETG-CF, ASA) but still needs an ACE 2 Pro for active drying[1][6] | Distinct from the earlier Saturn 4 Ultra (12K); the 16K carries a 15120 x 6230 masking LCD with 14 x 19 um pixels. Elegoo also sells it bundled with a Mercury Plus V2.0 wash/cure station and as a pre-owned SKU, neither of which is the printer-only price[2][3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 211.68 x 118.37 x 220 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 455.4 x 445.3 x 461.3 mm for the printer; the ACE 2 Pro, if added, is a separate 368 x 291.5 x 236.5 mm unit[1] | 327.4 x 329.2 x 548 mm[2] |
| Net weight (kg) | About 9.5 kg for the printer (Anycubic's own figure is approximate); packaged 13.2 kg bare or 18 kg as the Combo[1] | Not documented |
| Frame construction & material | Not documented | Metal housing with a flip-up cover and a drip guard[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Flip-up lid (Elegoo's own naming) over an open frame; UV-blocking cover[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Anycubic does not state a construction type for the Kobra X, but its dimensions, price and feature set match the gantry/bed-slinger Kobra 4 rather than the CoreXY S1 series[1][6] | MSLA with tilt-release: the vat tilts to peel each layer rather than pulling straight up. Elegoo claims the mechanism cuts curing time by 25%. Single Z axis, Z precision 0.02 mm[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | Not documented |
| Recommended/typical print speed | 300 mm/s recommended print speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Hardened-steel nozzle, 0.4 mm standard, expandable to 0.25, 0.6 and 0.8 mm[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C maximum nozzle temperature[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C maximum hotbed temperature on a PEI spring steel build plate[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 auto-levelling with Z-offset and area levelling[1] | Automatic levelling, plus intelligent mechanical sensor alarms[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, entanglement detection and power-loss resume[1] | Not documented |
| Multi-material/multi-color capability or official upgrade path | Native 4-colour printing built in, expandable to 19 colours; active drying still needs a separate ACE 2 Pro[1] | Not documented |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 V, 50/60 Hz, 24 V 6 A[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS with pressure advance and flow calibration supported[1] | Elegoo EL3D-4.0 system. Slicer is CHITUBOX[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 4-inch capacitive touchscreen (control panel — not the masking LCD, see W1)[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Control from the printer, the slicing software, the Anycubic app and USB (print only); AI spaghetti detection and object skip supported[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app and USB drive (print only)[1] | USB and Wi-Fi, with WLAN file transfer[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Standard HD camera fitted, 720p[1] | AI camera, 1920 x 1080[2] |
| Camera features: live monitor, timelapse, AI failure detection (spaghetti detection) — how real is it? | Not documented | AI camera with print-failure detection[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU, PVA, PLA-CF, PETG-CF, ASA[1] | 405 nm photopolymer resin; the heated tank is aimed at high-viscosity and high-speed resins. No closed compatibility list published[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 48 dB or less - a manufacturer figure with no mode, distance or method stated[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[7] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Not documented | 10-inch 16K monochrome masking LCD, 15120 x 6230 px, XY pixel pitch 14 x 19 um (manufacturer specification)[2][3] |
| Light source | Not documented | COB light source with a Fresnel collimating lens[2] |
| Light uniformity & intensity | Not documented | Light energy at the plate quoted as 5 mW/cm2, i.e. 5000 uW/cm2 (manufacturer claim, attributed to the tilt-release and Fresnel optics). No uniformity percentage published and no independent measurement[2] |
| Vertical print speedmm/h | Not documented | Up to 150 mm/h (manufacturer claim). Elegoo does not state the layer height or resin type the figure assumes[2] |
| Release film | Not documented | PFA release film. No rated life published[2] |
| LCD life & replaceability | Not documented | Masking LCD shielded by tempered 9H protective glass. Elegoo publishes no rated screen life in hours and does not state user replaceability[2] |
| Resin vat & feeding | Not documented | Replaceable resin vat with a dual pour spout and a drip guard. Heated tank with automatic temperature measurement: Elegoo states resin reaches 25 C in 26 minutes from a 5 C ambient at 50% humidity (manufacturer figure). 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.
