Additive manufacturing is the process of creating an object by building it one layer at a time. It is the opposite of subtractive manufacturing, in which an object is created by cutting away at a ...

Sometimes known as “3-D printing,” additive manufacturing uses emerging technologies to fabricate parts by building them up layer-by-layer. It allows rapid transformation from "art" (CAD model) to ...

Additive manufacturing, also known as 3D printing, has had a major impact on the contemporary design and production process. First developed in 1988 with the aim of allowing for rapid prototyping, ...

Scientists have developed a methodology for assessing the surface topography of 3D-printed layers using optical metrology. The method ensures the quality of parts printed with additive manufacturing ...
