EXTRUSION HEAD OF CORDS OF CONSTRUCTION MATERIALS OF AN ADDITIVE MANUFACTURING ROBOT EQUIPPED WITH A SMOOTHING DEVICE

摘要

The invention relates to an extrusion head for building material cords, a robot for additive manufacturing of architectural structures by stacking successive layers of extruded cords (8), said extrusion head comprising a housing (14), a building material inlet mouth, an outlet nozzle (22) for the extruded beads, a metering pump configured to be able to convey the building material from said inlet mouth to said outlet nozzle (22), characterized in that said extrusion head further comprises a device (40) for smoothing the extruded cords (8) comprising at least one movable effector (47, 48) configured to be able to interact with the side walls of the extruded cords (8) and positioning means (45, 46) of this active effector in the vicinity of at least one extruded bead (8) to be smoothed.
