| ASME Y14.46 - Product Definition for Additive Manufacturing | Reference | 2022 |
| Any process of additive manufacturing (AM), such as those defined by ISO/ASTM 52900. |
| A surface subset within a part or on a part surface that is bounded by a set of connected or intersecting edges. |
| A volume subset within a part that is bounded by a set of connected or intersecting surfaces. |
| Orthogonally oriented minimum perimeter cuboid that can span the maximum extents of the points on the surface of a 3D part. |
| The direction in which layers are added in an additive manufacturing (AM) process to build a part. |
| The conditions in which a part is created. |
| Identification of the location of the build relative to the build platform. |
| Of a machine, base which provides a surface upon which the building of the part/s is started and supported throughout the build process. |
| 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. |
| Total usable volume available in the machine for building parts. |
| Combines features that cannot easily be characterized by concise equations or algorithms (e.g., nonlinear, nonrepeating, random, etc.). |
| A feature that is identified with either a datum feature symbol or a datum target symbol(s). |
| A type of bounded volume region that encloses the entire part and in which other parts cannot be located or intersected. |
| Specifies, with tolerance, how physical characteristics are varied spatially (e.g., changes in material composition, color, density, porosity, or unit cell size). |
| Three dimensional geometric arrangement composed of connective links between vertices (points) creating a functional structure. |
| Situation when parts are made in one build cycle and are located such that their bounding boxes, arbitrarily oriented or otherwise, will overlap. |
| A specific product definition data set that defines a particular stage of manufacturing and conformance to specification. |
| The finer spaced irregularities of the surface texture that usually result from the inherent action of the production process or material condition. |
| Structure separate from the part geometry that is created in order to provide a base and anchor for the part during the building process. |
| A mathematical representation of a flat or curved bounded space having length and width but no thickness. A surface may consist of multiple surface patches adjacent on all internal edges. |
| The composite of certain deviations that are typical of the real surface. It includes roughness and waviness. |
| 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 path through space that an additive manufacturing (AM) tool follows on its way to producing the desired geometry of the layer. |
| A specific type of bounded region where gradient control applies. |
| 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. |
