This Standard covers the definitions of terms and features unique to additive manufacturing (AM) technologies with recommendations for their uniform specification in product definition data and in related documents. Additively manufactured parts or assemblies are referred to as “parts” throughout the Standard. The Standard extends to capturing relevant AM detail from design, manufacturing, and quality engineering.
Area where material is added, normally on the last deposited layer, which becomes the foundation upon which the next layer is formed. For the first layer, the build surface is often the build platform.
A test specimen defined by a standard, produced for the purpose of obtaining test results that comply with the requirements of the applicable product standard, sometimes built at the same time as the part for additive manufacturing processes.
Supplemental geometry, explicitly defined in the design model and similar to true profile, that may be used to control the form, size, orientation, or location of a functional collection of points, lines, surfaces, or any combination thereof.
The more widely spaced component of the surface texture. Waviness may be caused by such factors as machine or workpiece deflections, vibration, and chatter. Roughness may be considered as superimposed on a wavy surface.
