3D Printing: A New Mindset in Product Design

The terms “3D printing” and “additive manufacturing” refer to processes that automatically build objects layer-by-layer from computer data. The technology is already well used in many sectors including transportation, healthcare, military, and education. Uses include buildingconcept models, functional prototypes, factory tooling (such as molds and robotarm ends), and even finished goods (such as aircraft internal components). The aerospace and medical industries in particular have developed advanced applications for 3D printing. 3D printing is sometimes referred to as “rapid prototyping,” but this term does not encompass all current uses for the technology. Materials used in 3D printing include resins, plastics, and, in some cases, metal.
