How the two machines differ on paper: build volume, process, enclosure, nozzle temperature, launch year and the materials each manufacturer names. This is a specification comparison, not a hands-on test.

Published specifications don't settle print quality, reliability or noise. Compare the exact configuration, bundled accessories, regional price and support with each manufacturer, and check that the materials you need are supported on the configuration you'd buy.

CoreXY filament printer with four independently exchanged toolheads.
U1 includes four toolheads with automated offset calibration, filament feeding and backup mode. Its material paths stay separate, which is different from a single-hotend filament changer.
Full sourced profileDual-nozzle filament printer with active chamber heating.
The total reachable area is wider than the shared dual-nozzle envelope. The manufacturer also specifies a 700 × 700 × 1100 mm working space, which is larger than the chassis dimensions.
