Identity
BrandMarkforgedQIDI
ClassINDUSTRIALCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Markforged Onyx One Desktop 3D Printer[1]QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[2][3]
Release date (announcement and actual shipping)Not documentedAnnounced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[4]
Street price (USD; dated snapshot per entry)Not documented$649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[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]Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[3][2]
Market position: superseded? successor announced?Not documentedSuperseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[7][8]
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]305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)Not documented505 x 487 x 550 mm[4]
Net weight (kg)Not documented32 kg gross (3DJake). QIDI does not publish a net weight on the product page[4]
Frame construction & materialNot documentedEnclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed desktop cabinet[1]Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][4]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[2][4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Not documentedCoreXY[4]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedDual independent Z motors on 10 mm linear shafts and screws[2]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented600 mm/s (manufacturer claim, tool-head maximum)[4]
Max acceleration (claimed, mm/s²)Not documented<=20,000 mm/s2 (manufacturer claim)[4]
Extruder
Type (direct drive / bowden) & design nameSingle extruder — plastic only, no fibre channel[1]Direct drive with hardened steel dual gears, 1.75 mm filament[2][4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedSecond-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[2][4]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented<=370 °C claimed. No firmware max_temp verified for this model[2][4]
Heater cartridge power (W)Not documented80 W hotend heater (manufacturer figure)[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documentedConflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[2][4]
Bed surface (material, texture, coating), single/double-sidedNot documented6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][4]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedFull-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][4]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[4]
Multi-material/multi-color capability or official upgrade pathNot documentedQIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[2][3]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedAuxiliary part-cooling fan plus a chamber circulation fan; fan sizes and duct design not published[4]
Electronics & Power
Input voltage (110/220 V, switch or auto)Not documented100-240 VAC, 50/60 Hz[4]
Total rated power drawNot documented450 W plus 400 W for chamber heating (rated)[4]
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]Klipper v0.12, described by QIDI as open source. Fork details and current release not published on the product page[2]
Connectivity, UI & Camera
Display: size, type, touch?Not documented5-inch touchscreen, 800 x 480[2][4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveNot documentedWi-Fi 2.4 GHz, Ethernet, USB[2][4]
Cloud service & phone app; LAN-only mode possible?Not documentedMobile and computer control, remote cloud or LAN-only operation[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedBuilt-in low-frame-rate camera, up to 1080p, timelapse supported[2][4]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedQIDI claims about 10 minutes from unbox to printing[2]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery listed; mechanism not published[4]
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, ABS, ASA, PETG, TPU, PA, PC, PA-CF/GF, PET-CF/GF, PPA-CF/GF, PPS-CF and other CF/GF-filled polymers[2][4]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Not documented1-year coverage, 14-day no-reason return, 30-day price protection[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.
