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.

Compact MINI revision with the SuperPINDA bed-leveling sensor.
The MINI+ combines a remote filament drive with an automatic bed-probing routine and removable magnetic steel sheets. It still uses manual first-layer Z adjustment.
Full sourced profileOpen-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.
