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.

LCD resin printer with tilt release and a heated resin tank.
This 16K revision combines a heated tank with tilt-release separation. The source gives a 30 °C resin target. Its pixel grid and build dimensions differ from other Saturn 4 versions.
Full sourced profileLCD resin printer with chamber heating for detailed models.
The 16K revision uses a 14 × 19 µm pixel grid and a dual-rail ball-screw motion system. Pixel pitch is separate from the dimensional accuracy of a cured part.
