Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Formlabs Form 4 3D Printer[1][2]LulzBot TAZ Pro (LulzBot's own store lists it under Legacy LulzBot printers)[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]$4,950.00 on buy.lulzbot.com, in stock, 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]Several TAZ Pro derivatives exist and their specs differ substantially: TAZ Pro S, TAZ Pro XT+, and TAZ Pro Long Bed (282 x 582 x 285 mm, 1.2 mm GammaMaster steel nozzle, 80 °C bed cap, 150 mm/s travel, BLTouch 32-point mesh). The base TAZ Pro is 285 mm cubed with a 0.5 mm hardened-steel nozzle, a 110 °C bed and 300 mm/s travel — do not mix the two spec sets[3][4]
Physical & Frame

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]
Belts (type, width, e.g. Gates?)Not documentedGT2 belt drive[3]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documentedTrinamic TMC2130[3]
Speed & Acceleration
Max travel speedNot documented300 mm/s maximum travel speed (manufacturer figure)[3]
Extruder
Type (direct drive / bowden) & design nameNot documentedPro Dual Extruder tool head — two active-lifting hot ends for true dual-material printing[3]
Filament diameterNot documented2.85 mm standard, 1.75 mm optional[3]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented290 °C maximum hot end temperature[3]
Stock nozzle size & sizes included in boxNot documented0.5 mm hardened steel[3]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedHardened steel[3]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented110 °C maximum bed temperature[3]
Bed heater type (DC/AC mains) & wattageNot documented360 W, 24 V silicone bed heater[3]
Bed surface (material, texture, coating), single/double-sidedNot documentedDual-sided borosilicate glass with PEI film[3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedAutomatic 4-point mesh levelling using a 5 V contact circuit, plus automatic X-axis tramming, Z-offset and backlash compensation[3]
Mesh grid size (probe point count — firmware evidence)Not documented4-point mesh[3]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament sensor with both runout and stripping detection[3]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documented32-bit Archim 2.2b with Trinamic TMC2130 drivers[3]
PSU (brand, wattage, rail voltage)Not documented500 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 draw480 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]5-inch full-colour resistive touchscreen[3]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2]USB serial; a 16 GB flash drive is included for standalone printing[3]
Materials Support
Officially supported filament listFormlabs 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]
Safety
Certifications (UL/ETL/CE/FCC — verify, don't assume)Not documentedFCC, CE, RCM, ETL, CSA, OSHWA and WEEE. The OSHWA listing is the open-hardware certification[3]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Not documented1 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, not an independent measurement)[3]
Resin & MSLA
Masking LCDLow 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 sourceBacklight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[1][2]Not documented
Vertical print speedmm/hMaximum 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 range25-200 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 & feedingSingle 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.
