Material-Process Duality in Industrial 4D Printing

First published: 10 September 2022

Summary

This chapter discusses the material-process duality. With the advent of 4D printing, a pattern of “trust/defiance” is created and relies on the fact that social exchanges and their interactions are established in a determined psychological context, within a system that will impose sanctions in case of breaking the agreement and specific supports in case of respecting it. Harari introduced the concept of “dataism” which originates from the life sciences with their biochemical algorithms and digital algorithms (from which additive manufacturing and 4D printing are derived) and highlights close mathematical formalisms between the two, yet highly disjointed, fields. The physical–chemical information principle would have been used to evolve a multitude of different computational devices implemented in physical materials (but not using 4D printing). One of the biggest problems in materials exploitation is finding a good computational abstraction to carry the computation over the underlying physical process.
