Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Formlabs Form 4L[1]UltiMaker Factor 4[2]
Release date (announcement and actual shipping)Not documentedAnnounced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[2]
Launch MSRP (USD)Not documentedStarting at approximately $20,000[2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Same Low Force Display engine as the Form 4 but a different machine on every physical figure: 353 x 196 x 350 mm vs 200 x 125 x 210, 46 um vs 50 um pixels, 58.5 kg vs 18.3 kg, 900 W vs 480 W, two resin cartridges vs one. Formlabs lists Basic, Premium and Complete packages, whose prices are not printer-only prices, and no printer-only USD figure was found on a live listing[1]Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[1]330 x 240 x 300 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)664 x 528 x 794 mm[1]Not documented
Net weight (kg)58.5 kg[1]Not documented
Enclosure: open / enclosed; panel material; door/lidEnclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[1]Enclosed with actively controlled chamber airflow and a HEPA filter[2]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documentedBuild volume temperature controlled up to 70 °C with actively controlled chamber airflow (manufacturer specification)[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[1]Direct-drive dual extrusion; kinematic layout not stated in the source checked[2]
Extruder
Type (direct drive / bowden) & design nameNot documentedDirect-drive dual extrusion[2]
Filament diameterNot documented2.85 mm[2]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented340 °C maximum with the high-temperature print core (manufacturer claim)[2]
Filament Handling & Detection
Spool holder location & max spool size; drybox compatibilityNot documentedAutomatic climate-controlled material handling and storage station holding humidity below 15%, storing up to six spools[2]
Cooling & Air Handling
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documentedHEPA filter[2]
Electronics & Power
Input voltage (110/220 V, switch or auto)100-240 VAC, 9 A, 50/60 Hz, 900 W[1]Not documented
Total rated power draw900 W[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Proprietary; print preparation is PreForm[1]Not documented
Connectivity, UI & Camera
Display: size, type, touch?7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[1]Not documented
Materials Support
Officially supported filament listFormlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1]UltiMaker-branded PPS CF, PLA, Tough PLA, Nylon, PETG, PET CF and PVA, plus validated third-party materials from BASF Forward AM, Kimya, Polymaker, LEHVOSS and Jabil[2]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)XY dimensional tolerance +/-0.15% — a manufacturer specification[1]Dimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[2]
Resin & MSLA
Masking LCDLow Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[1]Not documented
Light sourceBacklight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[1]Not documented
Layer height range25-200 um[1]Not documented
Resin vat & feedingTwo next-generation resin cartridges. No vat capacity published[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.
