Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra S1 Max[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 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]$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 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]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 usable350 x 350 x 350 mm[1]280 x 280 x 270 mm advertised[2][3]

Frame construction & materialNot documentedAll-metal frame per QIDI's US page; no further breakdown published[3]
Enclosure: open / enclosed; panel material; door/lidFully 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]Fully enclosed with a heated chamber[2][3]
Passive chamber temperature reached (if enclosed; measured values preferred)65 C active chamber heating (manufacturer figure, actively heated rather than passive)[1]65 °C, independent chamber heating (manufacturer claim)[2][3]
Kinematics & Motion Hardware

Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedDouble 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 speed300 mm/s recommended print speed (manufacturer figure)[1]Not documented
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 documentedConflicting: 30 mm3/s (3DJake) vs 35 mm3/s (QIDI US page). Lower figure used[2][3]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion") with hardened-steel extruder gears, which Anycubic rates at six times the life of brass on carbon-fibre filament[1]High-flow direct-drive extruder, 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]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)350 C maximum nozzle temperature[1]<=350 °C claimed[2][3]

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.
