|---|---|---|
| Identity | ||
| Brand | Anycubic | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra S1 Max[1] | QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[2][3] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 16 January 2026 (Shopify publish date)[4] | Not published by QIDI on the pages checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | $699.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $899.00 ($804.00 for the EU plug variant)[4] | $399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The large enclosed Anycubic. Against the Kobra S1: 350 mm cube against 250 (Anycubic claims 174% more volume), 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 lacks entirely, a titanium-alloy throat tube and hardened-steel extruder gears, an activated carbon filter, 720p camera against 480p, and 25.7 kg against 9.37 kg. Its engineering-filament list is correspondingly longer[1][5] | Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[2][6][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 350 x 350 x 350 mm[1] | 175 x 180 x 170 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 502.7 x 483 x 584 mm[1] | 370 x 362 x 397 mm[2] |
| Net weight (kg) | 25.7 kg net, 31 kg packaged[1] | 10.5 kg[2] |
| Frame construction & material | Not documented | QIDI publishes no frame-material breakdown for this model[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed CoreXY with 65 C active chamber heating, dual external-circulation cooling fans and an activated carbon filter, plus a temperature and moisture display[1] | No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 65 C active chamber heating (manufacturer figure, actively heated rather than passive)[1] | Not documented |
| Kinematics & Motion Hardware | ||

| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1] | 20,000 mm/s2 (manufacturer claim)[3] |
| Max volumetric flow claimed (mm³/s) | Not documented | 30 mm3/s extruder flow (manufacturer claim)[2][3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion") with hardened-steel extruder gears, which Anycubic rates at six times the life of brass on carbon-fibre filament[1] | Direct-drive extruder, single, 1.75 mm filament[2][3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-release hotend with a titanium-alloy throat tube; 0.4 mm and 0.6 mm nozzles supplied, 0.25 and 0.8 mm optional; hardened steel[1] | Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2][3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C maximum nozzle temperature[1] | <=300 °C claimed[2][3] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C maximum hotbed temperature on a PEI spring steel build plate[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[1] | 16-point automatic bed levelling per QIDI's US page; probe technology not named[3] |

| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 48 dB or less in standard mode, as low as 45 dB in quiet mode - manufacturer figures with no 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[8] | 1-year coverage (QIDI standard store terms)[9] |
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.
