| Property | Anycubic Kobra S1COREXY | QIDI X-Plus 3COREXY |
|---|---|---|
| Identity | ||
| Brand | Anycubic | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1[1] | QIDI X-Plus 3, listed in QIDI navigation as X-Plus3[2][3] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[4] | Not published by QIDI on the pages checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | $349.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $549.00 ($401.00 for the EU plug variant)[4] | $699 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026. 3DJake lists the model as sold out[3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The CoreXY line, not to be confused with the gantry/bed-slinger Kobra 3, Kobra 4 and Kobra X. Within the S line the Kobra S1 Max is a much bigger machine: 350 mm cube against 250, a 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 does not have at all, and 25.7 kg against 9.37 kg. Multicolour is sold separately on both (ACE Pro / ACE 2 Pro)[1][5] | Two headline-speed figures circulate for this model: QIDI's own US page says 600 mm/s and 35 mm3/s, 3DJake's spec table says <=500 mm/s and 30 mm3/s. This is exactly the kind of sibling contamination the 3-series suffers (X-Max 3 is 600 mm/s / 35 mm3/s). Siblings: X-Max 3 (325x325x315, 900 W) and X-Smart 3 (175x180x170, no chamber heat, 300 °C)[2][3][6][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 250 x 250 mm[1] | 280 x 280 x 270 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 400 x 410 x 490 mm[1] | 511 x 527 x 529 mm[2] |
| Net weight (kg) | 9.37 kg net, 20.2 kg packaged[1] | 24.3 kg net[2] |
| Frame construction & material | Not documented | All-metal frame per QIDI's US page; no further breakdown published[3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed - Anycubic's own wording is "Fully Enclosed CoreXY Construction". There is no active chamber heating on the S1 (that is the S1 Max's addition)[1][5] | Fully enclosed with a heated chamber[2][3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, independent chamber heating (manufacturer claim)[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY (stated outright in Anycubic's specification table)[1] | CoreXY[2] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear optical axis of high-strength steel[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Double Z axis[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1] | Conflicting manufacturer claims: QIDI's US page says 600 mm/s, 3DJake's spec table says <=500 mm/s. The lower, more conservative figure is used as the sortable value[2][3] |
| 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 (manufacturer claims)[1] | 20,000 mm/s2 (manufacturer claim)[3] |
| Max volumetric flow claimed (mm³/s) | Not documented | Conflicting: 30 mm3/s (3DJake) vs 35 mm3/s (QIDI US page). Lower figure used[2][3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | High-flow direct-drive extruder, 1.75 mm filament[2][3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-release hotend; 0.4 mm standard nozzle expandable to 0.25, 0.6 and 0.8 mm[1] | Ceramic heating core. Copper-alloy nozzle head for normal materials, hardened-steel nozzle head for abrasives. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 320 C maximum nozzle temperature[1] | <=350 °C claimed[2][3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C maximum hotbed temperature on a PEI spring steel build plate - the highest bed ceiling of any Anycubic machine in this file except the S1 Max[1] | <=120 °C claimed[2][3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Double-sided flexible magnetic RF plate[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 auto-levelling with Z-offset, plus area levelling[1] | Automatic bed levelling; probe technology not named[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, filament entanglement detection and power-loss resume[1] | Filament detection fitted; type and location not published[2] |
| Multi-material/multi-color capability or official upgrade path | Multicolour is sold separately - the ACE Pro / ACE 2 Pro units are not included with the bare S1[1] | Not documented |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Cortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[2][3] |
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 50/60 Hz[2] |
| Total rated power draw | Not documented | 800 W rated[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS, with pressure advance and flow calibration supported[1] | Klipper[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen[1] | 5-inch touchscreen, 800 x 480[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus 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, USB (print only)[1] | Wi-Fi (150M 2.4G), Ethernet, USB flash drive[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Standard HD camera fitted, but only 480p - lower than the 720p units on the S1 Max, Kobra 4 and Kobra X[1][5][8] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU, ABS, ASA[1] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 46 dB or less in standard mode and 44 dB or less in quiet mode - manufacturer figures with no distance or method stated, so not comparable with an independently measured reading[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[9] | 1-year coverage (QIDI standard store terms)[10] |
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.
