Are you able to attach items like a large rover to a rocket in order to bring it to another planet?
It is possible to do this, but it isn’t a good idea. The large rover takes up a lot of space. If you brought all of the raw materials you need to build the printers. The space that a box for a large rover takes up could provide enough resource storage to build several platforms, storage, batteries and other buildings you need to quickly build up a settlement on another planet.
