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.

Open-frame filament printer offered assembled or as a kit.
A redesigned cooling system and high-flow nozzle distinguish MK4S from MK4. The revised airflow improves cooling around the deposited part, while nozzle throughput still depends on the chosen material.
Full sourced profileOriginal enclosed CoreXY model in the CORE One family.
The announcement describes active chamber-temperature control and an enclosure intended to accommodate PLA/PETG operation with the doors closed. This is the original CORE One generation; later plus variants retain their separate records. The monitoring camera was introduced as an option.
