Formlabs Form 4L vs Snapmaker U1 — documented properties and sources

Identity

ClassRESINTOOLCHANGER
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Formlabs Form 4L[1]Snapmaker U1 3D Printer[2]
Street price (USD; dated snapshot per entry)Not documented$849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[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]An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[1]270 x 270 x 270 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)664 x 528 x 794 mm[1]584 x 499 x 730 mm[2]
Net weight (kg)58.5 kg[1]18.2 kg[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[1]Open as sold; a top cover is an optional accessory that raises the supported material range[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[1]Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[2]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented500 mm/s maximum toolhead speed (manufacturer claim)[2]
Max acceleration (claimed, mm/s²)Not documented20,000 mm/s2 maximum (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)Not documented32 mm3/s maximum hotend flow (manufacturer claim)[2]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput shaping with an accelerometer, run as a calibration routine[2]
Extrusion Pressure Control
Pressure advance (Klipper) / linear advance (Marlin) supported?Not documentedPressure advance, with automatic flow compensation calibration[2]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented300 °C maximum (manufacturer claim)[2]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedStainless steel as standard; hardened steel needed for fibre-filled grades[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented100 °C maximum (manufacturer claim)[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedFlexible steel sheet with a PEI surface[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedMesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament run-out detection, plus air-printing detection and RFID filament recognition[2]
Multi-material/multi-color capability or official upgrade pathNot documentedFour toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedMain plus auxiliary part-cooling fans[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]Maximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Proprietary; print preparation is PreForm[1]Klipper[2]
Connectivity, UI & Camera
Display: size, type, touch?7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1]3.5-inch, 320 x 480 touchscreen[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[1]Wi-Fi 2.4 GHz (802.11b/g/n) and USB flash drive. No Ethernet listed[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documented2 MP built-in chamber camera for live view[2]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery supported; mechanism not published[2]
Materials Support
Officially supported filament listFormlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1]Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[2]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)XY dimensional tolerance +/-0.15% — a manufacturer specification[1]Not documented
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.
