| Property | Formlabs Form 4RESIN | QIDI X-Smart 3COREXY |
|---|---|---|
| Identity | ||
| Brand | Formlabs | QIDI |
| Class | RESIN | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4 3D Printer[1][2] | QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[3][4] |
| Release date (announcement and actual shipping) | Not documented | Not published by QIDI on the pages checked (Aug 2026)[3][4] |
| Street price (USD; dated snapshot per entry) | 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[2] | $399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[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[3][5][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[1][2] | 175 x 180 x 170 mm advertised[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 398 x 367 x 554 mm[1][2] | 370 x 362 x 397 mm[3] |
| Net weight (kg) | 18.3 kg[1][2] | 10.5 kg[3] |
| Frame construction & material | Not documented | QIDI publishes no frame-material breakdown for this model[3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a hinged 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[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[1][2] | CoreXY[3][4] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | <=500 mm/s (manufacturer claim)[3][4] |
| Max acceleration (claimed, mm/s²) | Not documented | 20,000 mm/s2 (manufacturer claim)[4] |
| Max volumetric flow claimed (mm³/s) | Not documented | 30 mm3/s extruder flow (manufacturer claim)[3][4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Direct-drive extruder, single, 1.75 mm filament[3][4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[3][4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | <=300 °C claimed[3][4] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | <=120 °C claimed[3][4] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Double-sided flexible magnetic RF plate[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | 16-point automatic bed levelling per QIDI's US page; probe technology not named[4] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 16 points (QIDI's US page). Not verified against firmware[4] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament detection fitted; type and location not published[3] |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Cortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[3] |
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 4.8 A, 50/60 Hz, 480 W[1] | 100-240 VAC, 50/60 Hz[3] |
| Total rated power draw | 480 W[1] | 350 W rated[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary. Print preparation is PreForm; fleet management is Formlabs Dashboard[2] | Klipper[4] |
| 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[4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2] | Wi-Fi and USB. No Ethernet listed for this model[3][4] |
| Materials Support | ||
| Officially supported filament list | 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[1] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 1-year coverage (QIDI standard store terms)[7] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[1][2] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Low 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[1][2] | Not documented |
| Light source | Backlight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[1][2] | Not documented |
| Vertical print speedmm/h | Maximum 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[2][1] | Not documented |
| Layer height range | 25-200 um per Formlabs' own tech-spec page; GoEngineer's listing for the same machine says 25-300 um. Unresolved[1][2] | Not documented |
| Resin vat & feeding | Single 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[1][2] | 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.
