Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Formlabs Form 4L[1]QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[2][3]
Release date (announcement and actual shipping)Not documentedNot published by QIDI on the pages checked (Aug 2026)[2][3]
Street price (USD; dated snapshot per entry)Not documented$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[3]
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]Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[2][4][5]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[1]175 x 180 x 170 mm advertised[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)664 x 528 x 794 mm[1]370 x 362 x 397 mm[2]
Net weight (kg)58.5 kg[1]10.5 kg[2]
Frame construction & materialNot documentedQIDI publishes no frame-material breakdown for this model[2]
Enclosure: open / enclosed; panel material; door/lidEnclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[1]No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[1]CoreXY[2][3]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented<=500 mm/s (manufacturer claim)[2][3]
Max acceleration (claimed, mm/s²)Not documented20,000 mm/s2 (manufacturer claim)[3]
Max volumetric flow claimed (mm³/s)Not documented30 mm3/s extruder flow (manufacturer claim)[2][3]
Extruder
Type (direct drive / bowden) & design nameNot documentedDirect-drive extruder, single, 1.75 mm filament[2][3]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedBrass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[2][3]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented<=300 °C claimed[2][3]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedBrass[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented<=120 °C claimed[2][3]
Bed surface (material, texture, coating), single/double-sidedNot documentedDouble-sided flexible magnetic RF plate[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documented16-point automatic bed levelling per QIDI's US page; probe technology not named[3]
Mesh grid size (probe point count — firmware evidence)Not documented16 points (QIDI's US page). Not verified against firmware[3]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament detection fitted; type and location not published[2]
Electronics & Power
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documentedCortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[2]
Input voltage (110/220 V, switch or auto)100-240 VAC, 9 A, 50/60 Hz, 900 W[1]100-240 VAC, 50/60 Hz[2]
Total rated power draw900 W[1]350 W rated[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Proprietary; print preparation is PreForm[1]Klipper[3]
Connectivity, UI & Camera
Display: size, type, touch?7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1]4.3-inch touchscreen[3]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[1]Wi-Fi and USB. No Ethernet listed for this model[2][3]
Materials Support
Officially supported filament listFormlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Not documented1-year coverage (QIDI standard store terms)[6]
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.
