Other terms that have been used as synonyms or hypernyms have included
desktop manufacturing, rapid manufacturing (as the logical
production-level successor to rapid prototyping), and on-demand
manufacturing (which echoes on-demand printing in the 2D sense of
printing). That such application of the adjectives rapid and on-demand
to the noun manufacturing was novel in the 2000s reveals the prevailing
mental model of the long industrial era in which almost all production
manufacturing involved long lead times for laborious tooling
development. Today, the term subtractive has not replaced the term
machining, instead complementing it when a term that covers any removal
method is needed. Agile tooling is the use of modular means to design
tooling that is produced by additive manufacturing or 3D printing
methods to enable quick prototyping and responses to tooling and fixture
needs. Agile tooling uses a cost effective and high quality method to
quickly respond to customer and market needs, and it can be used in
hydro-forming, stamping, injection molding and other manufacturing
processes.
