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.

Professional resin printer using Low Force Display technology.
The LFD engine combines an LED backlight, LCD masking and a flexible-film tank. Resin temperature, level and print forces are monitored. Published pixel size describes the imaging grid, not a general accuracy guarantee.
Full sourced profileUpdated Form 3 laser SLA platform with refined LFS hardware and a quicker part-release workflow.
The Plus revision updates optical-unit motion, heating and sensing. Its adaptive layer mode varies slicing thickness with geometry. The manufacturer’s relative speed claims depend on the job and material rather than describing a fixed throughput.
