Inefficiencies in Mass Production support 3D printer growth. Examples of these inefficiencies include: the stockpiling of components and parts, the large amount of working capital required for such stockpiling, profligate waste of materials, and any expenses involved with employing a large number of employees.
Technology for 3D printing will advance through loosely coordinated development in three areas: printers and printing methods, software to design and print, and materials used in printing.
The existing global capitalistic growth paradigm is totally flawed
The chaotic turbulence is the result of the concept of infinite bigness this has been the destructive influence on all empires and now shown up by Feigenbaum numbers and Dunbar numbers for neural netwoirks
See Guy Lakeman Bubble Theory for more details on keeping systems within finite limited size working capacity containers (villages communities)
