Self-replication of 3D universal structures

After a survey of some realizations of self-replicating machines, this paper presents the construction based self-replication of universal 3D structures. This self-replication process is achieved by translation and transcription of a configuration information in a three-dimensional data and signals cellular automaton (DSCA). The specifications and the design of the basic three-dimensional cell of the automaton results in a new and straightforward methodology for the self-replication of 3D computing machines of any dimensions.
