With the advancement of information and communication technology, manufacturing organisations are adopting digital manufacturing more than ever before. This gives rise to cloud-based manufacturing through which manufacturers can sell their production capabilities as an on-demand service termed as Manufacturing-as-a-Service (MaaS), instead of selling pre-defined products. Existing MaaS providers (e.g. online 3D printing providers) offer manufacturing customised products. But, customers have more demanding needs, such as rapid turnaround time, quality product, innovative design, etc. To meet such requirements, a Smart Manufacturing-as-a-Service (SmartMaaS) framework has been developed. In order to deliver efficient products at optimal cost, SmartMaaS can take smart actions such as negotiating with manufacturing centres (e.g. 3D printers) with respect to their availability, turnaround time, manufacturing cost, etc. In this paper, SmartMaaS is introduced and demonstrated via a prototype that is capable of accepting customers’ product request in the form of “design genes” and manufacturing 3D printed products through an actor-based system.
