| Property | Formlabs Form 4LRESIN | 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 4L[1] | LulzBot TAZ Pro Long Bed 3D Printer[2] |
| Street price (USD; dated snapshot per entry) | Not documented | $7,995.00 at MatterHackers, listed as currently 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] | 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[2][3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[1] | 282 x 582 x 285 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 |
| Frame construction & material | Not documented | Open frame; GT2 belt drive with Igus SST rods and polymer bushings[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[1] | Open frame, no enclosure[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[1] | Cartesian bedslinger[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic TMC2130[2] |
| Speed & Acceleration | ||
| Max travel speed | Not documented | 150 mm/s maximum travel speed, firmware-limited[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Asteroid 285 tool head[2] |
| Filament diameter | Not documented | 2.85 mm standard, 1.75 mm optional[2] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 290 °C maximum, firmware-limited[2] |
| Stock nozzle size & sizes included in box | Not documented | 1.2 mm GammaMaster steel[2] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | GammaMaster steel[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 80 °C maximum bed temperature — notably lower than the base TAZ Pro[2] |
| Bed heater type (DC/AC mains) & wattage | Not documented | 360 W, 24 V silicone bed heater[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Blue spring-steel magnetic flex bed system[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | BLTouch, 32-point automatic mesh calibration[2] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 32 points[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensor with runout and stripping detection[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | 32-bit Archim 2.2b with Trinamic TMC2130 drivers[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 500 W 24 V Mean Well, auto-switching, 100-240 VAC input[2] |
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 9 A, 50/60 Hz, 900 W[1] | Not documented |
| Total rated power draw | 900 W[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary; print preparation is PreForm[1] | Marlin[2] |
| 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, USB-C 2.0[1] | USB serial; 16 GB flash drive included for standalone printing[2] |
| Materials Support | ||
| Officially supported filament list | Formlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1] | PLA, TPU, ABS, PETG, PVA, PVB, nylon, PC and other materials below 290 °C[2] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 1 year standard with extended options. Made in the USA[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification[1] | Positional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification)[2] |
| Resin & MSLA | ||
| Masking LCD | Low Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[1] | Not documented |
| Light source | Backlight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[1] | Not documented |
| Layer height range | 25-200 um[1] | Not documented |
| Resin vat & feeding | Two 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.
