ASME Y14.46 - Product Definition for Additive Manufacturing2022
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.
Reference ...
Any process of additive manufacturing (AM), such as those defined by ISO/ASTM 52900.

Additive Manufacturing
A surface subset within a part or on a part surface that is bounded by a set of connected or intersecting edges.

Part, Surface
A volume subset within a part that is bounded by a set of connected or intersecting surfaces.

Bounding Box
    
Orthogonally oriented minimum perimeter cuboid that can span the maximum extents of the points on the surface of a 3D part.
See Also:
Surface, Part
Build Direction
    
The direction in which layers are added in an additive manufacturing (AM) process to build a part.
See Also:
Additive Manufacturing, Part
The conditions in which a part is created.
See Also:
Part
Build Location
    
Identification of the location of the build relative to the build platform.
See Also:
Build Platform
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.
See Also:
Part
Build Surface
    
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.
See Also:
Build Platform
Build Volume
    
Total usable volume available in the machine for building parts.
See Also:
Part
Complex Geometry
    
Combines features that cannot easily be characterized by concise equations or algorithms (e.g., nonlinear, nonrepeating, random, etc.).
See Also:
Feature, Complex Feature
Datum Feature
    
A feature that is identified with either a datum feature symbol or a datum target symbol(s).
See Also:
Datum Feature Symbol, Datum Target Symbol
Free Zone
    
A type of bounded volume region that encloses the entire part and in which other parts cannot be located or intersected.
See Also:
Bounded Volume Region, Part
Gradient Control
    
Specifies, with tolerance, how physical characteristics are varied spatially (e.g., changes in material composition, color, density, porosity, or unit cell size).
See Also:
Tolerance
Three dimensional geometric arrangement composed of connective links between vertices (points) creating a functional structure.
See Also:
Geometric Element
Nesting
    
Situation when parts are made in one build cycle and are located such that their bounding boxes, arbitrarily oriented or otherwise, will overlap.
See Also:
Part, Bounding Box
A specific product definition data set that defines a particular stage of manufacturing and conformance to specification.
See Also:
Product Definition Data Set, TDP Type, Technical Data Package
A collection of one or more data file(s) that discloses, directly or by reference, by means of graphic or textual presentations, or combinations of both, the physical or functional requirements of an item.
See Also:
Data, Item, Product Definition
Roughness
    
The finer spaced irregularities of the surface texture that usually result from the inherent action of the production process or material condition.
See Also:
Surface Texture
Support
    
Structure separate from the part geometry that is created in order to provide a base and anchor for the part during the building process.
See Also:
Geometry, Part
Surface
    
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.
Surface Texture
    
The composite of certain deviations that are typical of the real surface. It includes roughness and waviness.
See Also:
Surface, Roughness, Waviness
Test Coupon
    
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.
See Also:
Standard, Product, Additive Manufacturing Process
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.
See Also:
Supplemental Geometry, Design Model, True Profile, Surface
Track Path
    
The path through space that an additive manufacturing (AM) tool follows on its way to producing the desired geometry of the layer.
See Also:
Additive Manufacturing, Geometry
A specific type of bounded region where gradient control applies.
See Also:
Gradient Control, Bounded Surface Region, ounded Volume Region
Waviness
    
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.
