Abstract

The aim of the invention is to provide a concrete printer which allows complex concrete elements and structures to be erected within a short time with the inclusion of a reinforcement and surfacing process. The concrete printer according to the invention, in particular for producing concrete elements and structures, has a vertically (Z) movable jack lift (6) which can be moved on two perpendicular rails (3) by a first drive unit (5). The jack lift (6) is connected to a longitudinal crossbeam (7) oriented horizontally in the longitudinal direction (X), and the longitudinal crossbeam (7) is connected to two guide rails (8) oriented in the longitudinal direction (X). A transverse crossbeam (9) which is oriented perpendicularly to the longitudinal crossbeam (7) can be moved along the guide rails (8) by a second drive unit (10), and at least one working head (13) is provided which can be moved along the transverse crossbeam (9), comprises at least one concrete printing nozzle (11), and can be moved by a third drive unit (12). The actuation of all the drive units (4, 5, 10, 12) and the concrete printing nozzles (11, 11a, 11b) is carried out by a control unit (41). In the method according to the invention, supporting concrete (18) is first cast or dispensed from a supporting concrete nozzle (11a) for an outer contour (18) and/or an inner contour (18). Reinforcement rods (31) are then optionally inserted, and the intermediate spaces (47) between the supporting concrete portions (18) and optional reinforcement rods (31) are then cast with liquid concrete (19) from the liquid concrete nozzle (11b).
