Title: SYSTEMS, DEVICES, AND METHODS FOR FORMING THREE-DIMENSIONAL PRODUCTS WITH EMBEDDED RFID ELEMENTS
Abstract:
A technique for forming a product with an embedded RFID element is disclosed. An extruder can extrude a first material and a second material onto a print bed. The first material has multiple RFID chips dispersed throughout the first material, and the second material has metallic particles dispersed throughout the second material to achieve a specified concentration of metallic particles. A computing system controls the extruder to print a three dimensional product on the print bed using the first extrusion material and the second extrusion material. The computing system also controls the rate at which the first material and the second material is extruded in order to electrically couple at least one of the RFID chips to at least some of the metallic particles in the three dimensional product to form an RFID tag embedded in the three dimensional product that is readable by an RFID reader.
