ClassBEDSLINGERCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 3 Max[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 19 February 2025 (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)$429.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $699.00 ($493.00 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)Same 420 x 420 x 500 mm build volume as the older Kobra 2 Max, so build volume will not tell them apart - but the Kobra 3 Max is faster (600 mm/s claimed against 500), runs Kobra OS with multi-colour support and a 4.3-inch touchscreen, and is lighter at 19 kg against 21 kg. Its acceleration ceiling is 10000 mm/s2, half the 20000 mm/s2 of the smaller Kobra 3 - a difference the marketing does not lead with[1][6][7]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Market position: superseded?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 documentedSuperseded 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[8][9]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable420 x 420 x 500 mm, which Anycubic states as 88 L[1]305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][5]
Machine footprint (mm) & clearance needed (cable/spool overhang)706 x 640 x 753 mm[1]505 x 487 x 550 mm[5]
Net weight (kg)19 kg[1]32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5]
Frame construction & materialNot documentedEnclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2]
Enclosure: open / enclosed; panel material; door/lidOpen 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 documented65 °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 table gives the construction as "Gantry System" - a bed-slinger, with dual Y-axis motors added to stop layer misalignment on the large moving bed[1]CoreXY[5]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedDual independent Z motors on 10 mm linear shafts and screws[2]
Belts (type, width, e.g. Gates?)Semi-automatic belt tensioning, which Anycubic pairs with motor anti-skip[1]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]600 mm/s (manufacturer claim, tool-head maximum)[5]
Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)10000 mm/s2 maximum acceleration - half the ceiling of the smaller Kobra 3, because of the moving mass[1][7]<=20,000 mm/s2 (manufacturer claim)[5]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion") with a quick-release hotend[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 with an aerospace-grade ceramic composite throat tube; 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[1]<=370 °C claimed. No firmware max_temp verified for this model[2][5]
Heater cartridge power (W)Not documented80 W hotend heater (manufacturer figure)[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit90 C maximum hotbed temperature on a PEI spring steel plate - 20 C below the smaller Kobra 3[1][7]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]
Heat-up time to 60°C (measured preferred)Anycubic claims the ultra-large hotbed heats up in 125 s; no target temperature is stated for that figure and it is a manufacturer claim, not a measurement[1]Not documented
Bed surface (material, texture, coating), single/double-sidedNot documented6 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 and 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, entanglement 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 pathSupports 4- or 8-colour printing with ACE Pro 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 designNot documentedAuxiliary part-cooling fan plus a chamber circulation fan; fan sizes and duct design not published[5]

Total rated power drawNot documented450 W plus 400 W for chamber heating (rated)[5]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS; Anycubic Slicer Next is 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[1]5-inch touchscreen, 800 x 480[2][5]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus slicer, Anycubic app and USB (print only); AI spaghetti detection and object skip supported[1]Not documented

Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedBuilt-in low-frame-rate camera, up to 1080p, timelapse supported[2][5]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedQIDI 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 documentedPower-loss recovery listed; mechanism not published[5]
Materials Support
Officially supported filament listPLA, PETG, TPU (TPU is not compatible with the ACE Pro)[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]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)60 dB or less in standard mode - a manufacturer figure with no distance or method stated; markedly higher than the 46-48 dB Anycubic claims for the Kobra S1 and Kobra 4[1][10][11]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[12]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.
