| Property | Formlabs Form 4RESIN | LulzBot TAZ Pro Long BedBEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | Formlabs | LulzBot |
| Class | RESIN | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4 3D Printer[1][2] | LulzBot TAZ Pro Long Bed 3D Printer[3] |
| 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] | $7,995.00 at MatterHackers, listed as currently unavailable, checked Aug 2026[3] |
| 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] | Not simply a longer TAZ Pro. The Long Bed ships the Asteroid 285 tool head with a 1.2 mm nozzle, a 0.3-0.9 mm equipped layer range, an 80 °C bed cap (vs 110 °C), 150 mm/s travel (vs 300) and BLTouch 32-point mesh levelling (vs 4-point contact). Bed material also differs: blue spring-steel magnetic flex rather than glass with PEI film[3][4] |
| 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] | 282 x 582 x 285 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 398 x 367 x 554 mm[1][2] | Not documented |
| Net weight (kg) | 18.3 kg[1][2] | Not documented |
| Frame construction & material | Not documented | Open frame; GT2 belt drive with Igus SST rods and polymer bushings[3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[1] | Open frame, no enclosure[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[1][2] | Cartesian bedslinger[3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic TMC2130[3] |
| Speed & Acceleration | ||
| Max travel speed | Not documented | 150 mm/s maximum travel speed, firmware-limited[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Asteroid 285 tool head[3] |
| Filament diameter | Not documented | 2.85 mm standard, 1.75 mm optional[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 290 °C maximum, firmware-limited[3] |
| Stock nozzle size & sizes included in box | Not documented | 1.2 mm GammaMaster steel[3] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | GammaMaster steel[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 80 °C maximum bed temperature — notably lower than the base TAZ Pro[3] |
| Bed heater type (DC/AC mains) & wattage | Not documented | 360 W, 24 V silicone bed heater[3] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Blue spring-steel magnetic flex bed system[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | BLTouch, 32-point automatic mesh calibration[3] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 32 points[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensor with runout and stripping detection[3] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | 32-bit Archim 2.2b with Trinamic TMC2130 drivers[3] |
| PSU (brand, wattage, rail voltage) | Not documented | 500 W 24 V Mean Well, auto-switching, 100-240 VAC input[3] |
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 4.8 A, 50/60 Hz, 480 W[1] | Not documented |
| Total rated power draw | 480 W[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary. Print preparation is PreForm; fleet management is Formlabs Dashboard[2] | Marlin[3] |
| 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-drive | Dual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2] | USB serial; 16 GB flash drive included for standalone printing[3] |
| 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] | PLA, TPU, ABS, PETG, PVA, PVB, nylon, PC and other materials below 290 °C[3] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 1 year standard with extended options. Made in the USA[3] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[1][2] | Positional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification)[3] |
| 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.
