| Property | Markforged Onyx OneINDUSTRIAL | Prusa CORE One L+COREXY |
|---|---|---|
| Identity | ||
| Brand | Markforged | Prusa Research |
| Class | INDUSTRIAL | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Markforged Onyx One Desktop 3D Printer[1] | Prusa CORE One L+[2] |
| Release date (announcement and actual shipping) | Not documented | The CORE One L+ refresh was announced on 13 August 2026 and went on sale immediately, with the first assembled units shipping at once; it adds GT1.5 belts and an integrated nozzle wiper to the CORE One L[3] |
| Street price (USD; dated snapshot per entry) | Not documented | $1,850.93 on prusa3d.com, Aug 2026; $1,925.00 with the Advanced Filtration bundle. Prusa's own comparison text on the CORE One+ page quotes "from $1,799", which does not match the live e-shop price[4][5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The defining limitation: the Onyx One prints Onyx only and has NO continuous-fibre reinforcement. The Onyx Pro adds fibreglass, the Mark Two adds the full continuous-fibre range, and the X7 is a much larger industrial machine. Onyx One specifications must never be read from Mark Two or X-series material lists[1][6][7] | Larger sibling of the CORE One+ (Gen 2): 300 x 300 x 330 mm against 250 x 220 x 270 mm, 60 C chamber against 55 C, 21.9 kg against 22.5 kg (the L is the lighter of the two despite being larger). A CORE One L to CORE One L+ upgrade kit exists, so "CORE One L" and "CORE One L+" are different revisions. A Critical Infrastructure Edition is also listed[2][5][4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 12.6 x 5.2 x 6.1 in (approximately 320 x 132 x 155 mm)[1] | 300 x 300 x 330 mm, which Prusa states as 29.7 litres[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 469 x 521 x 635 mm[2] |
| Net weight (kg) | Not documented | 21.9 kg (48.3 lb)[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed desktop cabinet[1] | Fully enclosed with a chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Active convection chamber heating, maximum 60 C (manufacturer figure)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Not documented | CoreXY - stated in Prusa's CORE One+ comparison table[5] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic drivers on the custom xBuddy mainboard (Prusa's CORE One L+ specification says "custom 32-bit xBuddy mainboard with STM32 processor & Trinamic drivers"; it does not give the driver part number)[2] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input Shaper and Phase Stepping with an integrated accelerometer[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Single extruder — plastic only, no fibre channel[1] | Nextruder direct drive with a 10:1 planetary gear system; all-metal hotend with an aluminium heatsink and a tool-free quick-swap nozzle system[2] |
| Gear ratio & drive gear material | Not documented | 10:1 planetary gearbox[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Tool-free quick-swap nozzle system; Prusa brass high-flow CHT 0.4 mm pre-mounted plus an abrasive-resistant 0.4 mm nozzle in the box[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 290 C claimed max nozzle temperature. The optional HT hotend that raises this to 400 C was announced for September 2026 availability, so it is not a shipping specification as of Aug 2026[2][3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 120 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Magnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Custom 32-bit xBuddy mainboard with an STM32 processor[2] |
| Total rated power draw | Not documented | Standby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (manufacturer figures)[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary; slicing and print management run in Markforged's cloud-based Eiger software[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[8][9] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 3.5-inch 65k-colour touch screen (CORE One family)[5] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Not documented | On-device touch UI with Prusa Connect and Prusa mobile app remote control[5] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Not documented | Ethernet, NFC receiver and Wi-Fi through a physically removable module, which Prusa offers for high-security offline installations[2] |
| Materials Support | ||
| Officially supported filament list | Onyx only — Markforged's nylon filled with chopped carbon fibre. Markforged claims parts 1.4x stronger than ABS and heat deflection to 293 °F (145 °C)[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB, and with Advanced Filtration also ABS, ASA, HIPS and PA[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[10][8] |
| 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][9] |
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.
