Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Markforged Onyx One Desktop 3D Printer[1]Prusa CORE One+ (Gen 2) INDX, listed as "INDX 4-Tool" and "INDX 8-Tool" variants and as an "INDX 8-Tool Assembly kit"[2][3]
Release date (announcement and actual shipping)Not documentedAnnounced as shipping on 20 August 2026 ("INDX, Shipping Has Started, Complete Printers Open for Orders"). Prusa's own front page in Aug 2026 announces "Prusa CORE One+ (Gen 2) INDX, Shipping Has Started, Complete Printers Open for Orders", with the assembled 8-tool machine quoted as shipping from 15 October and the kit from 29 October[4][2]
Street price (USD; dated snapshot per entry)Not documented$1,850.93 for the INDX 4-Tool and $2,082.41 for the INDX 8-Tool on prusa3d.com, Aug 2026; the 8-Tool assembly kit is $1,804.63. Camera and filtration bundles run to $2,152.78[2][3]
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][5][6]INDX is a multi-tool option on the CORE One+ (Gen 2) product page rather than a separate printer, sold in 4-tool and 8-tool configurations, plus a CORE One/+ INDX conversion kit for existing machines. All of the body, hotend, bed and electronics figures below come from that shared CORE One+ (Gen 2) page and were not published separately for the INDX machine, so treat them as platform figures. Prusa also sells the unrelated MMU3, which multiplexes five filaments through one nozzle[3][2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable12.6 x 5.2 x 6.1 in (approximately 320 x 132 x 155 mm)[1]250 x 220 x 270 mm - the CORE One+ (Gen 2) figure from the shared product page; Prusa does not publish a separate INDX build volume[3]
Machine footprint (mm) & clearance needed (cable/spool overhang)Not documented415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[3]
Enclosure: open / enclosed; panel material; door/lidEnclosed desktop cabinet[1]Fully enclosed with active chamber heating up to 55 C (shared CORE One+ platform)[3]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Not documentedCoreXY with a multi-tool head-changing system (INDX); Prusa's comparison table gives CoreXY for the CORE One family[3]
Extruder
Type (direct drive / bowden) & design nameSingle extruder — plastic only, no fibre channel[1]Nextruder direct drive, 10:1 planetary gearbox (shared platform)[3]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented290 C claimed max nozzle temperature, 400 C with the optional HT hotend (shared platform)[3]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented120 C max heatbed temperature (shared platform)[3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedLoad-cell sensor, fully automatic first-layer calibration (shared platform)[3]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament sensors fitted (two on the CORE One+ platform)[3]
Multi-material/multi-color capability or official upgrade pathNot documentedINDX gives up to eight filaments; the alternative MMU3 handles five through a single nozzle[3]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit xBuddy board with STM32 (shared platform)[3]
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[7][8]
Connectivity, UI & Camera
Display: size, type, touch?Not documented3.5-inch 65k-colour touch screen (shared platform)[3]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveNot documentedEthernet and Wi-Fi, USB drive (shared platform)[3]
Materials Support
Officially supported filament listOnyx 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; ABS, ASA, HIPS and PA as advanced materials in the heated chamber (shared platform)[3]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Not documented2-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[9][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.
