| Property | FlashForge AD5XCOREXY | Original Prusa i3 MK3S+BEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | FlashForge | Prusa Research |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Flashforge AD5X, sold as "AD5X - Multicolor 3D Printer for High-Speed, Full-Color Printing"[1][2] | Original Prusa i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[3] |
| Street price (USD; dated snapshot per entry) | $399.00 sale against a $549.00 compare-at price on flashforge.com, in stock, with a further $50 off at checkout, checked Aug 2026. A refurbished AD5X is listed at $315.00[1][2] | $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[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Shares the 220 mm Adventurer chassis with the 5M and 5M Pro but differs on the points that matter: 300 °C nozzle (vs 280 °C), 4-colour IFS unit, NO air filtration, NO auto shutdown, and a 300 mm/s print speed against a 600 mm/s travel speed. 3DJake and eolasprints both describe it as open-frame[1][4][5][6] | 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[3][7][8][9] |
| Market position: superseded? successor announced? | Not documented | Superseded by the MK4/MK4S line.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[8][9] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 220 x 220 x 220 mm advertised[1][4] | 25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 500 x 550 x 400 mm (X x Y x Z), without the spool holder[3] |
| Net weight (kg) | Not documented | 7 kg (without spool)[3] |
| Frame construction & material | Not documented | Cut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[8] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure and no air filtration — FlashForge's own table records "Air Filtration: No". Chamber lighting and remote monitoring are listed as expandable options rather than fitted[1][5] | Open frame; the Original Prusa Enclosure is an optional separate product[8] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[5] | 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[8] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic 2130 drivers at 256 microstepping on the EINSY RAMBo 8-bit board, co-developed with UltiMachine; sensorless homing on X and Y[3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | FlashForge publishes two separate figures: max travel speed 600 mm/s and max print speed 300 mm/s. The 300 mm/s print figure is the one that describes printing[1][4] | Not documented |
| Max travel speed | Not documented | "200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[3] |
| Max acceleration (claimed, mm/s²) | 20,000 mm/s2 maximum (manufacturer claim)[1][4] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive, one extruder, fed by the 4-colour Intelligent Filament System (IFS)[1] | Direct drive with Bondtech gears and an E3D V6 hotend[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 °C claimed[1][4] | 300 C claimed max nozzle temperature[3] |
| Stock nozzle size & sizes included in box | 0.4 mm default; 0.25, 0.6 and 0.8 mm optional[1][4] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 °C claimed[1][4] | 120 C max heatbed temperature[3] |
| Bed surface (material, texture, coating), single/double-sided | PEI flexible spring-steel sheet[1][4] | Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling; probe technology not named[1][4] | SuperPINDA inductive probe (Prusa's temperature-drift-free replacement for the original PINDA), driving automatic mesh bed levelling and a self-test routine[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted; type and location not published[1][4] | IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[3] |
| Multi-material/multi-color capability or official upgrade path | Four-colour printing via the integrated Intelligent Filament System (IFS), which handles filament switching[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | EINSY RAMBo 8-bit board, co-developed with UltiMachine[3] |
| Input voltage (110/220 V, switch or auto) | Not documented | Custom Delta PSU with hardware-based power panic[3] |
| Total rated power draw | Not documented | Power consumption 80 W on PLA settings, 120 W on ABS settings[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named by FlashForge; the supported slicers are Orca-Flashforge and OrcaSlicer[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[10] |
| Connectivity, UI & Camera | ||
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB, Ethernet, Wi-Fi[1][4] | SD card (16 GB card included); Ethernet and Wi-Fi only via an optional Raspberry Pi[3] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Power-outage recovery supported; mechanism not published[1][4] | Not documented |
| Materials Support | ||
| Officially supported filament list | PETG, PLA, TPU95A, TPU64D-75D, PLA-CF, PETG-CF[1][4] | PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, carbon-filled, woodfill and other filled materials[3] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Prusa shipped Thermal Model protection to the MK3 line as a firmware update shortly before the MK4 launch; the firmware is open-source and auditable[8][10] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 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][12] |
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.
