Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 2 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 31 August 2023 (Shopify publish date)[1]Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[4]
Street price (USD; dated snapshot per entry)$639.00 on store.anycubic.com, Aug 2026[1]$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)Largest Kobra 2. Shares the Plus's 90 C bed ceiling and 500/300 mm/s figures but scales to 420 x 420 x 500 mm and 21 kg. Anycubic's on-page comparison is against the older Kobra Max (450 x 400 x 400 mm, Bowden, 180 mm/s), not against the Kobra 2 Plus. Note the newer Kobra 3 Max has the same 420 x 420 x 500 mm volume - build volume alone will not distinguish them[1][5][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Market position: superseded?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 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[7][8]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable500 x 420 x 420 mm stated HWD, i.e. 420 x 420 x 500 mm; Anycubic quotes 88.2 L[1]305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)740 x 735 x 640 mm stated HWD - footprint about 735 x 640 mm; this is a floor- or bench-dominating machine[1]505 x 487 x 550 mm[4]
Net weight (kg)21 kg[1]32 kg gross (3DJake). QIDI does not publish a net weight on the product page[4]
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][4]
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][4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger with double metal spindles on X and Y and included belt tensioners[1]CoreXY[4]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashDual-motor dual Z axis[1]Dual independent Z motors on 10 mm linear shafts and screws[2]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s maximum print speed (Anycubic Lab figure)[1]600 mm/s (manufacturer claim, tool-head maximum)[4]
Recommended/typical print speed300 mm/s typical print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)Not documented<=20,000 mm/s2 (manufacturer claim)[4]
Vibration Compensation / Input Shaping

Extruder
Type (direct drive / bowden) & design nameDirect extruder with double gears[1]Direct drive with hardened steel dual gears, 1.75 mm filament[2][4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedSecond-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][4]
Max nozzle temp claimed AND firmware max temp limit (both values)260 C nozzle temperature ceiling; 0.4 mm replaceable nozzle[1]<=370 °C claimed. No firmware max_temp verified for this model[2][4]
Heater cartridge power (W)Not documented80 W hotend heater (manufacturer figure)[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit90 C hotbed temperature ceiling[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][4]
Bed surface (material, texture, coating), single/double-sidedPEI magnetic spring steel plate, 420 x 420 mm[1]6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][4]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Anycubic LeviQ 2.0 automatic levelling, 49-point, with smart Z-offset[1]Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][4]

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[10]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.
