| ASME Y14.46 - Product Definition for Additive Manufacturing | Reference | 2022 |
| Definition: Any process of additive manufacturing (AM), such as those defined by ISO/ASTM 52900. |
| Term: Bounded Surface Region |  |
| Definition: A surface subset within a part or on a part surface that bounds a set of connected or intersecting edges. |
| Term: Bounded Volume Region | |
| Definition: A subset of 3D space within a part that bounds a set of connected or intersecting surfaces. |
| Term: Bounding Box | |
| Definition: Orthogonally oriented minimum perimeter cuboid that can span the maximum extents of the points on the surface of a 3D part. |
| Term: Build Direction | |
| Definition: The line or course in which layers are added in an AM process to produce a part. |
| Term: Build Environment | |
| Definition: The conditions in which a part is created. |
| Term: Build Location | |
| Definition: Identification of the site where the part will be produced relative to the build platform. |
| Term: Build Platform | |
| Definition: Of a machine, base which provides a surface upon which the building of the part/s is started and supported throughout the build process. |
| Term: Build Surface | |
| Definition: 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. |
| Term: Build Volume | |
| Definition: Total usable volume available in the machine for building parts. |
| Term: Complex Geometry | |
| Definition: A Combination of features that cannot easily be characterized by concise equations or algorithms (e.g., nonlinear, nonrepeating, random). |
| Term: Free Zone | |
| Definition: A type of bounded volume region that encloses the entire part and in which other parts cannot be located or intersected. |
| Term: Gradient Control | |
| Definition: Specifies, with tolerance, how physical characteristics are varied spatially (e.g., changes in material composition, color, density, porosity, or unit cell size). |
| Term: Lattice Structures | |
| Definition: Three dimensional geometric arrangement composed of connective links between vertices (points) creating a functional structure. |
| Term: Nesting | |
| Definition: Situation when parts are made in one build cycle and are located such that their bounding boxes, arbitrarily oriented or otherwise, will overlap. |
| Definition: A specific product definition data set designation that defines a particular stage of manufacturing and conformance to specification. |
| Term: Roughness | |
| Definition: The finer spaced irregularities of the surface texture that usually result from the inherent action of the production process or material condition. |
| Term: Support | |
| Definition: Structure separate from the part geometry that is created in order to provide a base and anchor for the part during the building process. |
| Term: Surface Texture | |
| Definition: The composite of certain deviations that are typical of the real surface. Surface texture includes roughness and waviness. |
| Term: Test Coupon | |
| Definition: 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. |
| Definition: 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. |
| Term: Track Path | |
| Definition: The additive manufacturing machine-material interface path through space for producing the desired geometry of the layer. |
| Term: Transition Region | |
| Definition: A bounded region where gradient control applies. |
| Term: Waviness | |
| Definition: 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. |
