Abstract

A deposition plane for additive manufacturing processes comprises a work surface (2) and a handling device. The work surface (2) is topologically deformable in at least one deformation zone and has a first face (2a) on which an object can be formed. The handling device comprises at least one actuator (3) coupled to a second face (2b) of the work surface (2) at the at least one deformation zone. Such a handling device is configured to locally deform the work surface (2) by moving the deformation zone thereof, preferably by exerting a pulling or pushing action on said deformation zone by means of the actuator (3).

Abstract

A method for the production of filaments (A) capable of being thermoregulated includes the steps of: —feeding a material to be extruded and a pair of wires (B) in electrically conductive material to an extrusion head (1); —extruding the material to be extruded and, at the same time, promoting the escape of the pair of wires (B) from the extrusion head (1) in such a way that the material to be extruded winds the pair of wires (B); —during the extrusion, generating at least a coupling portion (Y) of the filament (A), wherein the pair of wires (B) is electrically connected.
