Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Flashforge Creator 4, sold in A and S configurations (Creator 4A, Creator 4S)[1]Original Prusa MK4[2]
Release date (announcement and actual shipping)Not documentedAnnounced 29 March 2023 with assembled printers shipping immediately from stock; kits opened for ordering about two weeks later[2]
Launch MSRP (USD)Not documented1099 USD assembled, 799 USD as a kit, VAT included, at launch[2]
Street price (USD; dated snapshot per entry)$10,999.00 at Top 3D Shop with a 2-3 week lead time, checked Aug 2026[1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Two factory configurations that share the chassis but not the temperature ceiling: Creator 4A ships 2 x HT extruders (320 °C max, no composite support), Creator 4S ships 1 x HT + 1 x HS (360 °C max, supports PA-CF, PA-GF, PP-CF, PPS-CF). A third extruder type, F, is rated 265 °C and intended for flexibles. Any published "360 °C" figure applies only to the HS head[1]Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD MK4-to-MK4S upgrade kit and automatically converted unshipped MK4 orders to the S version. The MK3.5 and MK3.9 upgrades convert an MK3S+ to part of the MK4 electronics stack but are not an MK4[3][2]
Market position: superseded? successor announced?Not documentedDiscontinued. No MK4 appears in Prusa's Aug 2026 3D-printer listing, and the MK4 product-page slugs redirect to the MK4S page, so no live first-party price could be recorded[4][3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable400 x 350 x 500 mm[1]250 x 210 x 220 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)840 x 675 x 1000 mm (1050 mm on the stand). FlashForge specifies an installation space of at least 1400 x 1500 x 1600 mm[1]Not documented
Net weight (kg)90 kg net[1]Not documented
Frame construction & materialFully enclosed professional chassis on a stand[1]Die-cast aluminium frame - Prusa replaced the MK3S+'s cut-aluminium frame for the MK4, keeping only the Y-axis profiles, some bearings, the heatbed and the power supply[2]
Enclosure: open / enclosed; panel material; door/lidFully enclosed with HEPA 13 filtration and an actively controlled chamber[1]Open frame; the Original Prusa Enclosure is an optional add-on[2]
Passive chamber temperature reached (if enclosed; measured values preferred)Up to 65 °C, actively controlled (manufacturer claim)[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)IDEX — two independently driven extruders on the same gantry[1]Cartesian bed-slinger of the Prusa i3 family - Prusa's MK4 announcement records that the MK3S+ Y-axis profiles and heatbed were carried over[2]
Stepper motors (frame size, step angle, brand if known)Not documented400-step (0.9 degree) stepper motors, stated by Prusa to prevent vertical fine artefacts[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic TMC2130-LA silent stepper drivers on the xBuddy board[2]
Speed & Acceleration
Max print speed (claimed, mm/s)10-200 mm/s, adjustable per material. On the 4S the HS head is quoted 100-150 mm/s and the HT head 100-200 mm/s (manufacturer figures)[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect drive, two independent extruders, interchangeable modules (F / HT / HS)[1]Nextruder direct drive with a planetary gear system, 1:10 gearbox ratio; aluminium heatsink, all-metal hotend, no PTFE tube in the filament path[2]
Gear ratio & drive gear materialNot documented1:10 planetary gearbox[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedQuick-swap nozzle system, 0.4 mm default, other diameters supported[2]
Max nozzle temp claimed AND firmware max temp limit (both values)Depends on the fitted extruder module: F 265 °C, HT 320 °C, HS 360 °C[1]300 C claimed max hotend temperature in Prusa's MK4 announcement table - note the MK4S product page publishes 290 C for the same hotend family[2][5]
Stock nozzle size & sizes included in box0.4 mm default; 0.6 and 0.8 mm optional[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit130 °C maximum (manufacturer claim)[1]120 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedMagnetic heatbed with removable PEI spring-steel sheets; compatible with the MK3 sheets (smooth PEI, satin, textured PEI, PA nylon)[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Automatic bed levelling; FlashForge does not name the probe technology in this spec table[1]Load-cell sensor: fully automatic first-layer calibration with the nozzle as the probe, plus automatic mesh bed levelling over the print area[2]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedBuilt-in Hall-effect filament sensor supporting automatic filament loading[2]
Spool holder location & max spool size; drybox compatibilityTwo spool bays, 1 kg and 2 kg capacity[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit xBuddy board with STM32, designed and built in-house, with a separate extruder breakout board[2]
PSU (brand, wattage, rail voltage)Not documented240 W Delta PSU with hardware power panic[2]
Input voltage (110/220 V, switch or auto)AC 100-130 V / 200-240 V, 50-60 Hz, 30 A overcurrent protection[1]Not documented
Total rated power draw2320 W rated[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named; the supported slicer is FlashPrint[1]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[6][5]
Connectivity, UI & Camera
Display: size, type, touch?7-inch touchscreen, 1024 x 600[1]3.5-inch 65k-colour graphic screen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Not documentedOn-device colour UI with one-click printing and status LEDs; Prusa Link is integrated and Prusa Connect adds remote printing[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB flash drive, Ethernet, Wi-Fi[1]Ethernet built in, optional ESP Wi-Fi module delivered with the printer, USB drive; print files can also arrive over LAN or the internet via Prusa Connect[2]
Materials Support
Officially supported filament listStandard and engineering plastics on the HT head; the HS head adds PA-CF, PA-GF, PP-CF and PPS-CF. Materials such as PC, PA and carbon fibre are the stated targets for the 130 °C bed[1]Prusa's launch table says "any thermoplastic including Nylon and Polycarbonate"; the enclosure is still needed in practice for ABS/ASA-class materials[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)Not documentedxBuddy hardware overcurrent protection disconnects heater and heatbed power when total current exceeds 15 A; firmware is open-source and auditable[2][6]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)12 months on the printer, 3 months on extruder parts[1]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[7][5]

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.
