| Property | FlashForge Guider 3 UltraINDUSTRIAL | Positron V3.2COREXY |
|---|---|---|
| Identity | ||
| Brand | FlashForge | Positron3D |
| Class | INDUSTRIAL | COREXY |
| 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] | LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[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 trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 330 x 330 x 600 mm with a single extruder; 300 x 330 x 600 mm when both extruders are in use[1] | 180 x 180 x 165 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 635 x 550 x 1070 mm; packaging 775 x 690 x 1235 mm[1] | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[2] |
| Net weight (kg) | 70 kg net, 86 kg gross[1] | 3 kg net; 5.5 kg with the hard case[2] |
| Frame construction & material | Enclosed professional chassis; FlashForge describes a lightweight, stable structure for high-speed operation[1] | Folding frame designed to fit in a filament box; supplied with a black hard case[2] |
| Enclosure: open / enclosed; panel material; door/lid | Closed design with an air filter fitted[1] | Open frame[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY with two extruders, per a third-party buyer's guide. FlashForge's own spec table does not state the kinematics[5][1] | CoreXY, inverted — the machine prints upside down[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 10-500 mm/s printing speed, 500 mm/s maximum travel speed (manufacturer figures)[1] | 250 mm/s maximum print speed (manufacturer claim)[2] |
| Max acceleration (claimed, mm/s²) | 20,000 mm/s2 maximum (manufacturer claim)[1] | 8,000 mm/s2 (manufacturer claim)[2] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Active vibration compensation, which FlashForge says was enhanced for this model. Implementation not named[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Two extruders[1] | Bowden-style, single extrusion[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | PS plated-copper nozzle, 0.4 mm[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C maximum extruder temperature (manufacturer claim)[1] | 260 °C maximum (manufacturer claim)[2] |
| Stock nozzle size & sizes included in box | 0.4 mm default; 0.6 and 0.8 mm optional[1] | Not documented |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Plated copper[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 °C bed setting supported (manufacturer figure)[1] | 85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[2] |
| Bed surface (material, texture, coating), single/double-sided | Replaceable flexible steel-plate platform, magnetic. No glass bed[1] | Heated removable ITO glass bed[2] |
| 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 | ||
| Filament runout sensor (type, location) | Filament run-out reminder[1] | Not documented |
| 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 | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | LDO Positron mainboard[2] |
| PSU (brand, wattage, rail voltage) | Not documented | DC 24 V, 200 W[2] |
| Input voltage (110/220 V, switch or auto) | AC 100-240 V, 50/60 Hz[1] | Not documented |
| Total rated power draw | 850 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] | Klipper[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 7-inch touch LCD[1] | 3.5-inch LCD touchscreen[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB, Ethernet, Wi-Fi, plus cloud[1] | Wi-Fi, USB, Ethernet[2] |
| 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 |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit, manufactured in China[2] |
| 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 |
| Materials Support | ||
| Officially supported filament list | PLA, ABS, HIPS, ASA, PETG, CoPA, PLA-CF, PETG-CF, PAHT-CF, PAHT-GF, PET-CF, PET-GF, PA12-CF, PA-CF, PA-GF, NexPA-CF25[1] | PLA and PETG only, per the manufacturer[2] |
| 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.
