Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 3 Max[1]Original Prusa i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 19 February 2025 (Shopify publish date)[3]Not documented
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)[3]$1,199.00 assembled, $899.00 as a kit, for the 10th Anniversary Edition on prusa3d.com, Aug 2026. This is above the price the standard MK3S+ sold at, so do not read it as the MK3S+ street price[2]
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][4][5]Only the 10th Anniversary Edition remains on sale; the standard MK3S+ is gone from Prusa's printer listing. Two official upgrade paths change the machine substantially and are frequently confused with it: MK3.5 (xBuddy board and new LCD, keeps the MK3 extruder) and MK3.9 (adds the Nextruder). A caution on Prusa's own pages: the "Awards & Press Reviews" paragraph about the MK3S is reproduced verbatim on the MINI+ product page, so award text found on a Prusa page does not necessarily belong to the printer on that page[2][6][7][8]
Market position: superseded? successor announced?Not documentedSuperseded by the MK4/MK4S line. Prusa cut MK3S+ prices at the MK4 launch in March 2023 and said it would keep selling the MK3S+ at a lower price and hold spare parts in stock[7][8]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable420 x 420 x 500 mm, which Anycubic states as 88 L[1]25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)706 x 640 x 753 mm[1]500 x 550 x 400 mm (X x Y x Z), without the spool holder[2]
Net weight (kg)19 kg[1]7 kg (without spool)[2]
Frame construction & materialNot documentedCut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[7]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame; the Original Prusa Enclosure is an optional separate product[7]
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]Cartesian i3 bed-slinger. Prusa's MK4 announcement notes the MK3S+ Y-axis profiles and heatbed were among the few parts carried into the MK4[7]
Belts (type, width, e.g. Gates?)Semi-automatic belt tensioning, which Anycubic pairs with motor anti-skip[1]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic 2130 drivers at 256 microstepping on the EINSY RAMBo 8-bit board, co-developed with UltiMachine; sensorless homing on X and Y[2]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]Not documented
Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]Not documented
Max travel speedNot documented"200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[2]
Max acceleration (claimed, mm/s²)10000 mm/s2 maximum acceleration - half the ceiling of the smaller Kobra 3, because of the moving mass[1][5]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion") with a quick-release hotend[1]Direct drive with Bondtech gears and an E3D V6 hotend[2]
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]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)300 C maximum nozzle temperature[1]300 C claimed max nozzle temperature[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][5]120 C max heatbed temperature[2]
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 documentedRemovable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[2]
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]SuperPINDA inductive probe (Prusa's temperature-drift-free replacement for the original PINDA), driving automatic mesh bed levelling and a self-test routine[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, entanglement detection and power-loss resume[1]IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[2]
Multi-material/multi-color capability or official upgrade pathSupports 4- or 8-colour printing with ACE Pro units[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedEINSY RAMBo 8-bit board, co-developed with UltiMachine[2]
Input voltage (110/220 V, switch or auto)Not documentedCustom Delta PSU with hardware-based power panic[2]
Total rated power drawNot documentedPower consumption 80 W on PLA settings, 120 W on ABS settings[2]
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]prusa3d/Prusa-Firmware on GitHub, GPL-3.0, whose README states it is "proudly based on Marlin 1.0.x" and covers the MK3S/MK3/MK2.5S/MK2.5 line; last pushed August 2025. Updated over USB from a PC[9]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch capacitive touchscreen[1]Not documented
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
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app and USB drive (print only)[1]SD card (16 GB card included); Ethernet and Wi-Fi only via an optional Raspberry Pi[2]

Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedPrusa shipped Thermal Model protection to the MK3 line as a firmware update shortly before the MK4 launch; the firmware is open-source and auditable[7][9]
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]2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[13][14]

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.
