Abstract:
We evaluated our previously proposed technique to protect copyrights of digital data for 3-D printing. The technique embeds copyright information into not only digital data but also fabricated objects and enables the information to be reads to reveal possible copyright violations. In this study, copyright information was embedded into low infill density objects by constructing their inside with high infill density areas, and thermography was used for readout. An experiment was conducted to examine whether high infill density areas can be recognized from thermal images. The results indicated that they can be. We demonstrated that our technique is applicable to low infill density objects.
