Concrete preparation
The wet-mix pump needs a separate mixer; the dry-mix arrangement can feed from a silo. Mortar particle size must match the installed pump and delivery diameter.
Configuration details
The page gives a 4 mm aggregate limit for DN35 and 6 mm only with the additional DN50 kit. Its 1,200 mm cubic build-area label says PRO despite the EDU page title, so that ambiguous envelope has not been added as an EDU specification.

Model identity and process documented by the manufacturer. No rectangular build envelope or launch year is inferred.
A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
