|a The introduction of affordable 3D printers made a significant impact on personal fabrication artistic designs that may or may not be covered by Intellectual Property Rights (IPR). Therefore copyright holders or creators of 3D objects have a legitimate concern about sharing 3D objects. This work presents a model for signing printable 3D objects to address the IPR issue. 3D files contain object geometry plus a number of attributes however it lacks security attributes when it comes to provenance procedures as it uses inherited security protocols for digital documents, digital media that are not intended for 3D objects. This paper reviews security principles of signing of objects in digital form, and the metrics for assessing digital signatures, then illustrate the shortcoming of digital signing principles and current provenance procedures for 3D printed object from digital sources.. The proposed digital signing methodology aims to transition all the meta data associated with the digital 3D object to the physical 3D printed object The new model allows the transition of provenance between digital and physical form. At the same time it will follow archival principles to maintain accurate records and provide provenance.
