Novel means of copy protection for 3D printing or additive manufacturing design files. Our invention is a method of copy protection and unique identification of ownership as it applies to standard file formats for 3D printing and/or additive manufacturing. It works by embedding a unique identifier into common 3D printing digital files. Once our unique identifier is inserted into design, it can be used to identify potential theft and/or misuse of traced digital designs.

Abstract: Described within is a unique copy protection mechanism for 3D designs. It incorporates high resolution digital thumbprints into the design itself. The traced design can then be circulated into the general usage. Subsequent copying of the design will retain this information and provide a means to identify if a particular design has been copied by subtracting the digital thumbprint from the suspect design file and comparison with the original file.

The plan details including implant sizes and positions, surgical guide drill options, as well as the choice of a surgical kit, are all conveyed by the master model. Meanwhile, models of specially designed “implant inserts (or replicas)” are also generated, which have one end that fits into the implant holes on the master model and another end to make the surgical guide. The master model and inserts are manufactured with rapid prototyping technology. A surgical guide is later on made from them with conventional lab processes. A main characteristic of this approach is that the master model and the inserts are the physical embodiment of a virtual treatment plan. With them, the surgeons can continue the treatment planning for operations like tooth extractions and bone modifications before making the surgical guides. Therefore the treatment planning workflow is a combination of digital treatment planning and a physical model based planning, in other words, a hybrid approach. A differentiator in this invention is the generation of a closed solid model of the soft tissue, as part of the master model, from the scan data. This approach can be applied to create both bone-borne and tissue-borne surgical guides with low cost process, which is a big advantage over other approaches.
