| Class | BEDSLINGER | COREXY |
| 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] | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[2][4] |
| Street price (USD; dated snapshot per entry) | $4,950.00 on buy.lulzbot.com, in stock, checked Aug 2026[1] | $1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[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][5] | Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[2][4] |

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.
