Manufacturing process of a positioning control tool via 3D-printing technology comprising the following steps in order to form a gyroscope: - 3D-print a first part of framework with an insulating 3D-printing polymer material, such as to form a recipient laid on the print bed , - 3D-print a set of layers of piezoelectric substrate inside the first part of framework based on a polymer material mixed with powdered graphene inside said first part of framework; - 3D-print a pattern having a plurality of apertures therethrough; - 3D-print with a polymer material mixed with powdered graphene , using said pattern , a plurality of features on said substrate , said features comprising: - a resonator transducer for creating a first surface acoustic wave on said surface of the piezoelectric substrate ; - a pair of reflectors for reflecting said first surface acoustic wave to form a standing wave within a first region of said surface between said pair of reflectors ; - a structure within said region , wherein a Coriolis force acting upon said structure creates a second surface acoustic wave ; and - a first sensor transducer disposed on said surface for sensing said second surface acoustic wave ; and - a second sensor transducer disposed on said surface for sensing a residual surface acoustic wave from a second region of said surface that is free of any structure that said Coriolis force is able to act upon, and for providing an output indicative of said residual surface acoustic wave; - 3D-print a second part of framework with an insulating 3D-printing polymer material, such as to form a complete framework to protect and guaranty the working of the piezoelectric substrate with the features embedded. - 3D-print a first part of framework with an insulating 3D-printing polymer material, such as to form a recipient laid on the print bed , - 3D-print a set of layers of piezoelectric substrate inside the first part of framework based on a polymer material mixed with powdered graphene inside said first part of framework; - 3D-print a pattern having a plurality of apertures therethrough; - 3D-print with a polymer material mixed with powdered graphene , using said pattern , a plurality of features on said substrate , said features comprising: - a resonator transducer for creating a first surface acoustic wave on said surface of the piezoelectric substrate ; - a pair of reflectors for reflecting said first surface acoustic wave to form a standing wave within a first region of said surface between said pair of reflectors ; - a structure within said region , wherein a Coriolis force acting upon said structure creates a second surface acoustic wave ; and - a first sensor transducer disposed on said surface for sensing said second surface acoustic wave ; and - a second sensor transducer disposed on said surface for sensing a residual surface acoustic wave from a second region of said surface that is free of any structure that said Coriolis force is able to act upon, and for providing an output indicative of said residual surface acoustic wave; - 3D-print a second part of framework with an insulating 3D-printing polymer material, such as to form a complete framework to protect and guaranty the working of the piezoelectric substrate with the features embedded. <EOS>
