| Property | Anycubic Kobra 3 ComboBEDSLINGER | QIDI Plus4COREXY |
|---|---|---|
| Identity | ||
| Brand | Anycubic | QIDI |
| Class | BEDSLINGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra 3 Combo - the Kobra 3 sold together with the ACE Pro filament unit[1] | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[2][3] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 30 April 2024 (Shopify publish date)[4] | Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[5] |
| Street price (USD; dated snapshot per entry) | $329.00 with a US plug on store.anycubic.com, Aug 2026 ($355.00 for the EU plug variant)[4] | $649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Two things to watch here. First, the Combo is printer plus ACE Pro; the ACE Pro alone weighs 4.6 kg and measures 366 x 283 x 235 mm, so plan bench space for both. Second, Anycubic's own specification table on this page mixes generations - the weight row reads "Kobra 3 V2 - 9.2kg" while the package row reads "Kobra 3 - 12kg", and a separate Kobra 3 V2 Combo product is listed at the same price. Treat any single figure from this page as needing confirmation against the exact SKU[1][4][6] | Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[3][2] |
| Market position: superseded? successor announced? | Not documented | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[7][8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 250 x 260 mm; Anycubic quotes a 16.25 L maximum printing volume[1] | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 452.9 x 504.7 x 483 mm for the printer; the ACE Pro is a separate 365.94 x 282.84 x 234.5 mm box[1] | 505 x 487 x 550 mm[5] |
| Net weight (kg) | Anycubic's table gives "Kobra 3 V2 - 9.2kg" for the machine weight and "Kobra 3 - 12kg" for the package weight, plus 4.6 kg for the ACE Pro - the two rows do not refer to the same thing, so treat 9.2 kg as the machine and 12 kg as shipping weight[1] | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] |
| Frame construction & material | Not documented | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][5] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[2][5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Anycubic's specification table gives the construction as "Gantry System" - it is a bed-slinger, not the CoreXY layout used by the Kobra S1 series[1][9] | CoreXY[5] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Dual independent Z motors on 10 mm linear shafts and screws[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), with 300 mm/s recommended[1] | 600 mm/s (manufacturer claim, tool-head maximum)[5] |
| 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)[5] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive (Anycubic's term is "short distance extrusion")[1] | Direct drive with hardened steel dual gears, 1.75 mm filament[2][5] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | 300 C quick-release hotend; 0.4 mm standard nozzle, expandable to 0.6 and 0.8 mm[1] | Second-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[2][5] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C maximum nozzle temperature (manufacturer figure)[1] | <=370 °C claimed. No firmware max_temp verified for this model[2][5] |
| Heater cartridge power (W) | Not documented | 80 W hotend heater (manufacturer figure)[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C maximum hotbed temperature on a PEI spring steel build plate[1] | Conflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[2][5] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][5] |
| 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] | Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, filament entanglement detection, nozzle clog detection and power-loss resume[1] | Filament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[5] |
| Multi-material/multi-color capability or official upgrade path | 4-colour printing with one ACE Pro, or up to 8 colours with two units[1] | QIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[2][3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Auxiliary part-cooling fan plus a chamber circulation fan; fan sizes and duct design not published[5] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 50/60 Hz[5] |
| Total rated power draw | Not documented | 450 W plus 400 W for chamber heating (rated)[5] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS. Anycubic's slicer, Anycubic Slicer Next, is stated to be built on the open-source Orca slicer[1] | Klipper v0.12, described by QIDI as open source. Fork details and current release not published on the product page[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen with a 30-60 degree adjustable tilt[1] | 5-inch touchscreen, 800 x 480[2][5] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus Anycubic Slicer Next, the Anycubic app and USB (print only); AI spaghetti detection and object skip are 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] | Wi-Fi 2.4 GHz, Ethernet, USB[2][5] |
| Cloud service & phone app; LAN-only mode possible? | Not documented | Mobile and computer control, remote cloud or LAN-only operation[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Camera is optional on the Kobra 3 - a 720p HD unit, not fitted as standard, unlike the Kobra S1, Kobra 4 and Kobra X[1][9][10] | Built-in low-frame-rate camera, up to 1080p, timelapse supported[2][5] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | QIDI claims about 10 minutes from unbox to printing[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery listed; mechanism not published[5] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG and TPU, and Anycubic notes TPU is not compatible with the ACE Pro multi-material unit[1] | PLA, ABS, ASA, PETG, TPU, PA, PC, PA-CF/GF, PET-CF/GF, PPA-CF/GF, PPS-CF and other CF/GF-filled polymers[2][5] |
| 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[11] | 1-year coverage, 14-day no-reason return, 30-day price protection[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.
