Read this with the specifications
The official Pro S sheet identifies a 55 µm minimum feature size for Pro55 S. This is distinct from finished-part accuracy. Pro55 S specifications are not transferred to the earlier Pro55 model.
A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
