Additive manufacturing (AM), or 3D printing, is an emerging manufacturing technology that is expected to have far-reaching socioeconomic, environmental, and geopolitical implications. As the use of this technology increases, the need for validation of 3D designs grows. In order to create a marketplace in which 3D designs are traded, it is necessary to develop a platform that enables the attestation of the 3D designs and promotes truthfulness. In this paper, we introduce a novel concept of a distributed marketplace that will support the attestation of
3D printing designs. We build a mathematical trust model that
ensures truthfulness among rational, selfish, and independent
agents, which is based on a reward/penalty system. The payment
for participating in the evaluation is calculated by factoring in
agents’ reputation and peer feedback. Moreover, we describe
the architecture and the implementation of the trust model on
blockchain using smart contracts for the creation of a distributed
marketplace. Our model relies both on theoretical and practical
best practices to create an unique platform that elicit effort and
truthfulness from the participants.
