|---|---|---|
| Identity | ||
| Brand | LulzBot | UniFormation |
| Class | BEDSLINGER | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | LulzBot TAZ Pro (LulzBot's own store lists it under Legacy LulzBot printers)[1] | UniFormation GKtwo 10.3" 8K Resin Printer[2][3] |
| Street price (USD; dated snapshot per entry) | $4,950.00 on buy.lulzbot.com, in stock, checked Aug 2026[1] | $749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[1][4] | UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[2] |

| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic 4-point mesh levelling using a 5 V contact circuit, plus automatic X-axis tramming, Z-offset and backlash compensation[1] | Not documented |
| Mesh grid size (probe point count — firmware evidence) | 4-point mesh[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament sensor with both runout and stripping detection[1] | Not documented |

| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Positional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification, not an independent measurement)[1] | Printing tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[2] |

| Layer height range | Not documented | 0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[2][3] |
| Resin vat & feeding | Not documented | Resin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[2][3] |

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.
