Product marking systems play a key role in many existing manufacturing systems. With the rise of 3D printing applications, there is host of new opportunities to provide object tagging capabilities directly on product surfaces. Ideally, a solution could take advantage of existing infrastructure, which in many instances is adapted to use 1D barcodes. This paper explores different mechanisms for rendering barcodes directly onto object surfaces, including the benefits and challenges associated with mapping a 1D marking onto a 3D surface v. forms of pre-compensation for perspective correction such that the marking can be interpreted as flat from certain viewpoints. Objects with circular geometry are of key interest as they highlight differences between these two approaches.
