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 i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[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]$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)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]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][3][4][5]
Market position: superseded?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[4][5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable400 x 350 x 500 mm[1]25 x 21 x 21 cm = 250 x 210 x 210 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]500 x 550 x 400 mm (X x Y x Z), without the spool holder[2]
Net weight (kg)90 kg net[1]7 kg (without spool)[2]
Frame construction & materialFully enclosed professional chassis on a stand[1]Cut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[4]
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 separate product[4]
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 i3 bed-slinger. Prusa's MK4 announcement notes the MK3S+ Y-axis profiles and heatbed were among the few parts carried into the MK4[4]
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)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
Max travel speedNot documented"200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive, two independent extruders, interchangeable modules (F / HT / HS)[1]Direct drive with Bondtech gears and an E3D V6 hotend[2]
Hotend & Nozzle
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 nozzle temperature[2]
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 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)Automatic bed levelling; FlashForge does not name the probe technology in this spec table[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)Not documentedIR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[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 documentedEINSY RAMBo 8-bit board, co-developed with UltiMachine[2]
Input voltage (110/220 V, switch or auto)AC 100-130 V / 200-240 V, 50-60 Hz, 30 A overcurrent protection[1]Custom Delta PSU with hardware-based power panic[2]
Total rated power draw2320 W rated[1]Power consumption 80 W on PLA settings, 120 W on ABS settings[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named; the supported slicer is FlashPrint[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[6]
Connectivity, UI & Camera
Display: size, type, touch?7-inch touchscreen, 1024 x 600[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB flash drive, Ethernet, Wi-Fi[1]SD card (16 GB card included); Ethernet and Wi-Fi only via an optional Raspberry Pi[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]PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, carbon-filled, woodfill and other filled materials[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[4][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][8]

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.
