| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Vyper[1] | Original Prusa MK4S (Prusa Research, Prague). Sold as "Original Prusa MK4S 3D Printer" and "Original Prusa MK4S 3D Printer kit"[2][3] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 22 May 2021 (Shopify publish date)[1] | Announced and available to order on 12 August 2024, the date of Prusa's launch blog post, with assembled printers, kits and an MK4S/MMU3 bundle in stock at announcement[4] |
| Street price (USD; dated snapshot per entry) | $359.00 on store.anycubic.com, Aug 2026, with the compare-at price also $359.00 (no discount running) - notably more than the newer and much faster Kobra 2 at $169[1][5] | $925.00 assembled, $657.40 as a kit, on prusa3d.com, Aug 2026. Bundles: $1,171.11 with MMU3, $1,185.65 with the Enclosure, $1,438.33 with both[3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | A 2021-generation machine still on sale next to the far faster Kobra line. Its defining differences from every Kobra here: a Bowden extruder rather than direct drive, a 180 mm/s ceiling rather than 300-600 mm/s, and 16-point levelling rather than LeviQ 2.0/3.0. Do not read Kobra performance figures onto it[1][5][6] | The MK4S is a revision of the MK4, not a new platform: Prusa sold a $99 upgrade kit that gives an MK4 all of the MK4S features (360-degree turbine part cooling, high-flow CHT nozzle, firmware and profile changes). Watch the published nozzle ceiling: Prusa's MK4 announcement table says 300 C, while the MK4S product page says 290 C. Related family members are the MK3.5 and MK3.9 upgrades of the MK3S+, which are not the same machine. With the MMU3 the standard (non-high-flow) nozzle is the recommended one[4][7][2] |
| Market position: superseded? successor announced? | Effectively superseded by the Kobra line, but still listed for sale on the Anycubic store in Aug 2026[1] | Still sold in Aug 2026 as the entry point to the Nextruder line, positioned below the enclosed CORE One+ (Gen 2). Prusa also sells an MK4S-to-CORE One+ (Gen 2) conversion kit[3][2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 245 x 245 mm stated as HWD, i.e. 245 x 245 x 260 mm in the usual X x Y x Z order; Anycubic quotes a 15.6 L build volume[1] | 250 x 210 x 220 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 516 x 508 x 457 mm stated as HWD, so the desk footprint is about 508 x 457 mm[1] | 500 x 550 x 400 mm (X x Y x Z), stated without the spool holder[2] |
| Net weight (kg) | 10 kg[1] | 7 kg (without spool)[2] |
| Frame construction & material | Not documented | Aluminium extrusions and frame. Prusa's MK4 announcement records that the cut-aluminium frame of the MK3S+ was replaced by a die-cast aluminium frame for the MK4 platform, which the MK4S inherits[2][7] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Open frame. The Original Prusa Enclosure is a separate add-on and raises the achievable chamber temperature to 45 C; there is no active chamber heating[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian bed-slinger[1] | Cartesian bed-slinger - Prusa's own comparison table gives "Cartesian" for the MK4S against "CoreXY" for the CORE One and CORE One L[8] |
| Stepper motors (frame size, step angle, brand if known) | Not documented | 0.9 degree X and Y stepper motors, which Prusa states are used to prevent vertical fine artefacts[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | TMC2209 silent drivers on a 32-bit mainboard with a Cortex-M3 class main control chip - one of the few Anycubic machines where the driver part number is published[1] | Trinamic 2130. The MK4 announcement is more specific: TMC2130-LA drivers on the xBuddy board[2][7] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 180 mm/s maximum print speed with 80 mm/s recommended (manufacturer figures)[1] | Not documented |
| Recommended/typical print speed | 80 mm/s typical/recommended print speed (manufacturer figure)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Anycubic's own Bowden extruder - not direct drive[1] | Nextruder, direct drive, E3D V6 compatible with an adapter; Nextruder planetary gear system with a 10:1 gearbox ratio; aluminium heatsink and all-metal filament path[2] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox in the Nextruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Quick-swap Prusa nozzle system with an all-metal filament path; the MK4S ships with the high-flow Prusa brass CHT 0.4 mm nozzle. Standard (non-CHT) Prusa nozzles remain usable and are the recommended choice with the MMU3[2][4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 260 C operational nozzle temperature ceiling[1] | 290 C claimed max nozzle temperature on the MK4S product page (Prusa's MK4 announcement table gave 300 C for the MK4)[2][7] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C operational hot bed temperature ceiling[1] | 120 C max heatbed temperature (manufacturer figure)[2] |
| Bed surface (material, texture, coating), single/double-sided | PEI-coated stainless spring steel magnetic flexible platform, chosen by Anycubic over carborundum glass to avoid arching[1] | Magnetic heatbed with removable double-sided PEI spring-steel sheets; smooth PEI sheet supplied[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 16-point automatic levelling[1] | Load-cell sensor in the toolhead - the nozzle itself is the probe. First-layer calibration and mesh bed levelling over the print area only are fully automatic, with no Live Adjust Z step[2][7] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensor fitted as standard; on the MK4 platform this is a built-in Hall sensor that also drives automatic filament loading[2][7] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | High-performance turbine part-cooling fan with a 360-degree air-delivery duct - the headline change from the MK4, derived from work on Prusa's HT90 industrial machine. Fan RPM is monitored in firmware[2][4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Custom 32-bit xBuddy board with an STM32 MCU, designed, manufactured and tested in-house, plus a custom extruder breakout board for fans and thermistors[2][7] |
| PSU (brand, wattage, rail voltage) | Not documented | 240 W PSU custom-made by Delta with hardware power-panic support[2] |
| Total rated power draw | 100-240 V AC 50/60 Hz input; 24 V / 14.6 A (350 W) output[1] | Power consumption 80 W on PLA settings, 120 W on ABS settings (manufacturer figures)[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[9][2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch LCD touch-control screen[1] | 3.5-inch 65k-colour graphic screen with touch control[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Not documented | On-device colour UI with G-code preview and one-click printing; remote control and firmware updates through Prusa Connect and the Prusa mobile app[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | TransFlash (microSD) card; USB cable connection is flagged by Anycubic as being for expert users only[1] | Ethernet, Wi-Fi via the ESP module delivered with the printer, USB drive for print files, plus an NFC receiver used to hand over Wi-Fi credentials from the phone app[2][8][4] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Modular design with 4 major pre-assembled modules[1] | Sold both assembled (plug-and-print after a 10-minute self-test) and as an assembly kit[4] |
| Materials Support | ||
| Officially supported filament list | PLA, ABS, PETG, TPU and wood-filled filament[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB; ABS, ASA, HIPS and PA only when using the Original Prusa Enclosure with the filtration add-on[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | The xBuddy platform carries hardware overcurrent protection that disconnects heater and heatbed power when total current exceeds 15 A, and the firmware is open-source and auditable. Prusa also shipped Thermal Model protection to the earlier MK3 line[7][9] |
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | Not documented | Prusa states the MK4S is the first consumer 3D printer to receive UL GREENGUARD certification[2] |
| 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] | 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[11][2] |
| Spare parts availability & pricing (nozzle, hotend, plate, board, belts) | Not documented | Prusa cites a perfect 30/30 print-quality score from TechRadar and a CNET "Best Printer for Quality" title; these are quoted on Prusa's own page and were not verified against the original reviews here[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.
