ClassBEDSLINGERINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Original Prusa MK4[1]Stratasys F170, part of the Stratasys F123 Series[2]
Release date (announcement and actual shipping)Announced 29 March 2023 with assembled printers shipping immediately from stock; kits opened for ordering about two weeks later[1]The F123 series spec sheet carried is revision 0721a (July 2021). Stratasys does not print a launch date on it[2]
Launch MSRP (USD)1099 USD assembled, 799 USD as a kit, VAT included, at launch[1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Superseded by the MK4S, which is the same machine plus a 360-degree turbine part-cooling fan, a high-flow CHT nozzle and firmware/profile work; Prusa sold a 99 USD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][1]Shares its 254 mm cube with the F120 but is a different machine: full-size cabinet, 2 internal material spool bays (1 model, 1 support) in a front drawer, and five model materials. The F270 and F370 have 4 spool bays[2]
Market position: superseded? successor announced?Discontinued. 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]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 210 x 220 mm (manufacturer figure)[1]254 x 254 x 254 mm (10 x 10 x 10 in)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)Not documented1,626 x 864 x 711 mm (64 x 34 x 28 in)[2]
Net weight (kg)Not documented124 kg (F120) or 227 kg with consumables (F170, F270, F370)[2]
Frame construction & materialDie-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[1]Fully enclosed office/classroom-grade cabinet, factory assembled[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame; the Original Prusa Enclosure is an optional add-on[1]Enclosed build chamber[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger of the Prusa i3 family - Prusa's MK4 announcement records that the MK3S+ Y-axis profiles and heatbed were carried over[1]Not documented
Stepper motors (frame size, step angle, brand if known)400-step (0.9 degree) stepper motors, stated by Prusa to prevent vertical fine artefacts[1]Not documented
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Trinamic TMC2130-LA silent stepper drivers on the xBuddy board[1]Not documented
Extruder
Type (direct drive / bowden) & design nameNextruder direct drive with a planetary gear system, 1:10 gearbox ratio; aluminium heatsink, all-metal hotend, no PTFE tube in the filament path[1]Not documented
Gear ratio & drive gear material1:10 planetary gearbox[1]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Quick-swap nozzle system, 0.4 mm default, other diameters supported[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)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[1][5]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]Not documented
Bed surface (material, texture, coating), single/double-sidedMagnetic heatbed with removable PEI spring-steel sheets; compatible with the MK3 sheets (smooth PEI, satin, textured PEI, PA nylon)[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Load-cell sensor: fully automatic first-layer calibration with the nozzle as the probe, plus automatic mesh bed levelling over the print area[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Built-in Hall-effect filament sensor supporting automatic filament loading[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Custom 32-bit xBuddy board with STM32, designed and built in-house, with a separate extruder breakout board[1]Not documented
PSU (brand, wattage, rail voltage)240 W Delta PSU with hardware power panic[1]Not documented
Input voltage (110/220 V, switch or auto)Not documented100-132 V / 15 A or 200-240 V / 7 A, 50/60 Hz[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)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]Proprietary Stratasys firmware; print preparation is GrabCAD Print. The F370 additionally carries an Insight software licence and DoD STIG compliance powered by Red Hat Enterprise Linux[2]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch 65k-colour graphic screen[1]Not documented
On-device UI capabilities (model preview, per-object controls, etc.)On-device colour UI with one-click printing and status LEDs; Prusa Link is integrated and Prusa Connect adds remote printing[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveEthernet 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[1]Wired TCP/IP at 100 Mbps minimum, 100base-T Ethernet, RJ45. Wireless-ready IEEE 802.11 n/g/b with WPA2-PSK or 802.1x EAP, CCMP/TKIP encryption[2]
Materials Support
Officially supported filament listPrusa's launch table says "any thermoplastic including Nylon and Polycarbonate"; the enclosure is still needed in practice for ABS/ASA-class materials[1]PLA, ABS-M30, ASA, FDM TPU 92A, ABS-CF10, with QSR soluble support. PLA uses breakaway PLA support rather than soluble[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)xBuddy hardware overcurrent protection disconnects heater and heatbed power when total current exceeds 15 A; firmware is open-source and auditable[1][6]Not documented
Certifications (UL/ETL/CE/FCC — verify, don't assume)Not documentedCE (low-voltage and EMC directives), FCC, EAC, cTUVus, KC, RoHS, WEEE, REACH, RCM[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documented46 dB maximum during build, 35 dB idle — manufacturer specification, no distance or method stated, and not an independent measurement[2]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)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]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedParts produced within +/-0.200 mm or +/-0.002 mm/mm, whichever is greater. Manufacturer figure derived from statistical data at 95% dimensional yield; Z accuracy carries an extra -0.000/+slice-height tolerance[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.
