A plain-language overview of commercial additive manufacturing technologies, written for readers who may not work directly with the technology. Establishes what is — and is not — within the scope of this framework.

The word “sustainability” means different things in different contexts. This article defines what it means within this framework — and why the definition matters before the term can be applied to any manufacturing technology.

What this body of work does and does not cover. Defines vocabulary, establishes analytical limits, and sets technical boundaries so that readers with deep expertise can interpret the framework accurately.

Why capability alone rarely changes business outcomes. New manufacturing technologies have historically followed a pattern: capability is demonstrated, adoption is championed, yet systemic change lags. This article examines why — and what it means for additive manufacturing.

Additive manufacturing is not the first technology to promise transformation. This article places it within the longer arc of manufacturing evolution — not to diminish its significance, but to understand the structural patterns it shares with every technology that came before.
