Abstract: Personal fabrication tools such as 3D printers encourage designers for rapidly creating innovative prototypes of products. However, an immediate end product realisation is a challenge owing to several reasons, including permission delays. This paper proposes a blockchain-enabled architecture which explores the utilisation of decentralised connected 3D printers and decision-makers for collaboratively fabricating and installing societal products in smart cities - a social computing approach. Experiments were accomplished to manifest the proposed approach; besides, a case study of printing a Taj Mahal miniature was illustrated. The proposed mechanism would reap in lots of innovations and economic improvements in smart cities in the near future.

Keywords: blockchain; collaborative design; fabrication; distributed ledger; smart city; social good applications.
