In this paper, We demonstrate the application of self-assembly system for human manufacturing processes at meso-and macro-scale in order to pursue and expand the engineering applicability of self-assembly. First, we implemented a prototype referred to as ”self-assembly printer” which can generate a dynamic, transformable, two-dimensional moulding and reuse the units that compose the printed objects. Secondly, noteworthy technological components to explain our prototype system is introduced in this paper. Lastly, some potential application based on the system such as ”Self-Assembly Electronic Circuit (SAEC)” is implemented and proposed. As a result of these researches, our system attains scalability and alleviates the need for complex and accurate movements of assembler in traditional manufacturing system.
