Abstract

Combined electrospinning and microextrusion apparatus, comprising a robotic manipulator (10) provided with a plurality of degrees of freedom, an end effector (20) supported and movable by the robotic manipulator (10), a plurality of extruders (30) housed on the end effector (20), each of the extruders being provided with an interchangeable nozzle (31) for the extrusion of at least one material, a working plane (40) configured for the deposition of the extruded material, a pneumatic circuit (120) configured to supply a fluid flow to the extruders (30) for controlling the extrusion of the material, and an electric generator (50) selectively activatable to apply a potential difference between the nozzles (31) of the extruders (30) and the working plane (40), whereby the extruders (30) are capable of operating selectively in microextrusion mode with inactive electric generator or in electrospinning mode with active electric generator, in an independent manner from each other.
