Compared side by side

Who it's for
Shops that need ABS, ASA or nylon parts over 12.6 inches, or want to print several large parts per plate.
Caveats
- Early owners reported firmware and extruder problems after updates; back up settings before flashing.
- PLA clogs from heat creep if the chamber stays warm; QIDI sells a $199 Polar Cooler as the fix.
- At 103 lb it is a two-person lift.
- QIDI's own comparison lists it at $1,049; we could not confirm a higher regular price.
