Using RFID Technology to Prevent Unauthorized Copying of 3D-Printed Objects
The impact of this unique manufacturing technology is likely soon to be felt by industries worldwide.
May 16, 2018—
Three-dimensional printing, also known as additive manufacturing, is a breakthrough in the field of product design and manufacturing. It has gained wide popularity, mainly due to its lower cost than traditional manufacturing processes, rapid speed of production, agile design process, customization of designs and high accuracy. The technology involves creating physical objects from the digital model defined by a digital file, by adding input substrate materials using a layer-upon-layer printing method. 3D printing finds application in industries such as health care, automobiles, manufacturing, aerospace, jewelry, energy and construction, among others.
The 3D printing market is still very much in its infancy. However, the impact of this unique manufacturing technology is likely to be felt by industries all over the world soon. The factors driving the market include high accuracy, reduction of errors and risks, new applications for 3D printing technology, efficient use of raw materials, customization of products, advancement in technology, use of multiple materials such as metals, plastics, and ceramics for printing, and reduction of development cost and time. A report by Progressive Markets predicts that the global 3D printing market is anticipated to grow at a CAGR of 21 percent during the period of 2017 to 2025.
Several methods can be incorporated to provide an ID element in a 3D-printed object. For instance, the ID element may take the form of a radio frequency identification (RFID) tag embedded in the digital model. RFID is the application of radio waves to read and collect data stored on a tag attached to an object. Embedded with a transmitter and a receiver, an RFID tag or label can be read from some distance away and does not need to be within the view of the reader to be tracked.
The tags must be different for each 3D object so that they provide a unique identifier for the objects after they are read by an external RFID reader or sensor. The sensor detects the ID element within a 3D object to determine its authenticity. Records of the printing of 3D objects with ID elements can be stored in a central database, which can then be accessed by customers to determine the authenticity of a 3D object by scanning or processing the ID element.
In other words, the external database helps to verify that the 3D-printed object is original or has been printed directly from a certified digital file instead of being produced from an unlicensed copy or other illegal methods. Having an RFID tag or other ID elements in a 3D object may also benefit the manufacturing, inventorying and selling of the 3D object.
Several businesses launched novel printer technologies to control the illegal copying of their 3D-printed products. For instance, Disney, an American diversified multinational mass media and entertainment conglomerate, unveiled its patented technology that limits unauthorized reproduction of its 3D products and provides authentication of their objects.
The technology involves printing a model of a 3D-printed object with an ID element to control unauthorized copying. It involves controlling the 3D printer to print the layers of a 3D object along with an integrally formed ID element. This element, which is embedded within the 3D object, may be an RFID tag providing identification data when interrogated by an RFD reader. When the tag is activated by an external reader, it transmits ID data which includes a serial number that helps identify the ID element and the 3D object in which it has been formed.
