ClassINDUSTRIALRESIN
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]Formlabs Form 4 3D Printer[2][3]
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]Starting at $2,625.00 at GoEngineer, in stock, checked Aug 2026. Formlabs sells the printer as part of packages (Form 4 Complete Package etc.), so package prices are much higher than the printer-only figure[3]
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][4][5]Three machines share this platform and are constantly conflated. Form 4: 200 x 125 x 210 mm, 50 um pixels, 18.3 kg, 480 W, one resin cartridge, NOT biocompatible. Form 4B: identical hardware but validated for 38 Formlabs materials including 15 biocompatible. Form 4L: 353 x 196 x 350 mm, 46 um pixels, 58.5 kg, 900 W, two cartridges[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable330 x 330 x 600 mm with a single extruder; 300 x 330 x 600 mm when both extruders are in use[1]200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)635 x 550 x 1070 mm; packaging 775 x 690 x 1235 mm[1]398 x 367 x 554 mm[2][3]
Net weight (kg)70 kg net, 86 kg gross[1]18.3 kg[2][3]
Frame construction & materialEnclosed professional chassis; FlashForge describes a lightweight, stable structure for high-speed operation[1]Not documented
Enclosure: open / enclosed; panel material; door/lidClosed design with an air filter fitted[1]Enclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[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[6][1]Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[2][3]
Speed & Acceleration
Max print speed (claimed, mm/s)10-500 mm/s printing speed, 500 mm/s maximum travel speed (manufacturer figures)[1]Not documented
Max acceleration (claimed, mm/s²)20,000 mm/s2 maximum (manufacturer claim)[1]Not documented
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 nameTwo extruders[1]Not documented
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
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
Input voltage (110/220 V, switch or auto)AC 100-240 V, 50/60 Hz[1]100-240 VAC, 4.8 A, 50/60 Hz, 480 W[2]
Total rated power draw850 W maximum[1]480 W[2]
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. Print preparation is PreForm; fleet management is Formlabs Dashboard[3]
Connectivity, UI & Camera
Display: size, type, touch?7-inch touch LCD[1]7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB, Ethernet, Wi-Fi, plus cloud[1]Dual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[2][3]
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
Materials Support
Officially supported filament listPLA, 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]Formlabs resins across rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic and castable families. Biocompatible resins require the Form 4B, not the Form 4[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
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedXY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[2][3]
Resin & MSLA
Masking LCDNot documentedLow Force Display masking LCD with a 50 um pixel size and pre-tuned anti-aliasing. Formlabs does not publish the screen diagonal or pixel count[2][3]
Light sourceNot documentedBacklight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[2][3]
Vertical print speedmm/hNot documentedMaximum 100 mm/h; average 40 mm/h at a 100 um layer height (manufacturer figures — GoEngineer publishes both, which is unusually explicit about the basis). Formlabs separately claims most prints finish in under 2 hours[3][2]
Layer height rangeNot documented25-200 um per Formlabs' own tech-spec page; GoEngineer's listing for the same machine says 25-300 um. Unresolved[2][3]
Resin vat & feedingNot documentedSingle next-generation resin cartridge; Formlabs claims 5-10x faster filling and 63% less waste. Resin tank rated for 75,000+ layers with any Formlabs material. No vat capacity published[2][3]

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.
