Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Flashforge Guider 3 Ultra; the FlashForge spec table gives the machine name as "Guider 3 Ultra"[1]Markforged Onyx One Desktop 3D Printer[2]
Street price (USD; dated snapshot per entry)$2,399.00 against a $3,499.00 regular price on flashforge.com, but the listing checked is the refurbished SKU and is marked Sold out (Aug 2026)[1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Top of the Guider 3 series. Build size depends on which head is used: 330 x 330 x 600 mm with one extruder, 300 x 330 x 600 mm with both. Siblings Guider 3 (300x250x340) and Guider 3 Plus (350x350x600) are both single-extruder. A refurbished SKU exists alongside the new machine, so check which one a price refers to[1][3][4]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[2][5][6]
Physical & Frame

Extruder
Type (direct drive / bowden) & design nameTwo extruders[1]Single extruder — plastic only, no fibre channel[2]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)350 °C maximum extruder temperature (manufacturer claim)[1]Not documented
Stock nozzle size & sizes included in box0.4 mm default; 0.6 and 0.8 mm optional[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 °C bed setting supported (manufacturer figure)[1]Not documented
Bed surface (material, texture, coating), single/double-sidedReplaceable flexible steel-plate platform, magnetic. No glass bed[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Full-auto one-click levelling; probe technology not named[1]Not documented
Filament Handling & Detection

Cooling & Air Handling
Chamber/exhaust fan & filtration (activated carbon / HEPA)Air filter fitted; filter media not specified in the FlashForge table[1]Not documented
Electronics & Power
Input voltage (110/220 V, switch or auto)AC 100-240 V, 50/60 Hz[1]Not documented
Total rated power draw850 W maximum[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named; slicers are Orca-Flashforge and FlashPrint 5, with OrcaSlicer listed as compatible[1]Proprietary; slicing and print management run in Markforged's cloud-based Eiger software[2]
Connectivity, UI & Camera
Display: size, type, touch?7-inch touch LCD[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB, Ethernet, Wi-Fi, plus cloud[1]Not documented
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Remote camera monitoring and time-lapse video supported; resolution not published[1]Not documented
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Power-loss recovery supported; mechanism not published. Automatic shutdown also supported[1]Not documented

Safety
Certifications (UL/ETL/CE/FCC — verify, don't assume)CE, FCC, RoHS (as printed in FlashForge's own spec table)[1]Not documented

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.
