Plant for producing a concrete prefabricated component

A plant for producing a concrete prefabricated component, the plant comprising:

• a plurality of stations configured to allow a production pallet to pass therethrough in a circulating manner,
• a transport system configured to transport the production pallet through the plant,
• a water-binder mixture comprising water and a hydraulic cement-based binder,
• a mixing device configured to mix the water-binder mixture,
• a 3D printing station including:
• a layer depositing device configured to deposit layers of a particulate aggregate on the production pallet, and
• a printhead configured for controlled delivery of the water-binder mixture to at least one of the layers of the particulate aggregate deposited on the production pallet by the layer depositing device, to form a concrete prefabricated component,
• a storage device configured to store the particulate aggregate,
• a conveying device configured to convey the particulate aggregate stored in the storage device to the layer depositing device of the 3D printing station,
• a feed device configured to feed the water-binder mixture from the mixing device to the printhead of the 3D printing station, and
• an unpacking station configured to separate the concrete prefabricated component printed on the production pallet in the 3D printing station from an unbound portion of the particulate aggregate.
