1.1 This guide illustrates a test specimen geometry and testing protocol that can be used to assess the quality of a metal powder bed fusion build cycle as it could be affected by major system errors (for example, corrupted calibration, disrupted inert gas flow, laser wear) severely affecting the quality of materials fabricated by laser beam powder bed fusion (PBF-LB).

1.2 This method is designed to interrupt the manufacturing process if poor material quality is identified through go/no-go torque/angle of twist measurements of witness coupons after each fabrication.

1.1 This specification has been developed to facilitate exchanging and analyzing particle size distribution (PSD) by light scattering data from databases, data management systems, point of origin, or other data sources that may use different data dictionaries, schemas, or formats.

1.2 This specification prescribes the use of a common exchange format in such a way that PSD data defined through proprietary means can be easily exchanged for process understanding and qualification.

1.3 This specification facilitates the interoperability of PSD data by identifying the data elements defined in standardized terminology, as well as defining those salient terms with indisputable meanings. In doing so, this specification extends the common AM data dictionary defined in Practice F3490 to encapsulate PSD process-specific data elements. Generic data elements and relationships present in that standard are inherited and applied in this practice where relevant.

1.4 This specification specifies names that serve to uniquely identify the PSD data elements. The data type, value domain, and term definition for each data element are also specified in this practice. References are provided for those data elements with established definitions or reporting guidelines in existing standards.

1.5 This specification prescribes a file format and structure for the exchange of PSD data. This format defines a method for sharing data via the defined PSD data elements herein and provides a basis for validation of data exchanged using this format.

1.6 This specification recommends levels of data sharing that vary from minimal to robust. It prescribes best practices for checking conformance based on the common data exchange format.

1.7 This specification does not specify:

1.7.1 An exhaustive set of data items that could be exchanged related to PSD by light scattering.

1.7.2 A definition of a minimum viable data set for PSD by light scattering.

1.7.3 Data items or an exchange format for PSD methods other than light scattering, for example, imaging or sieving.

1.7.4 Data elements for data modules related to PSD (for example, for personnel, material, or equipment).

1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 The scope of this document outlines the interpretation of additive manufacturing (AM) data. Currently, legacy AM data is stored in different databases or data management systems, each of which uses its own data dictionary. A common data dictionary allows AM data pedigree to be discovered, mapped, federated, and analyzed to improve both the understanding and qualification of AM processes and parts.

1.2 A common data dictionary facilitates the interoperability, searchability, and reusability of AM data by (1) identifying the general AM data pedigree elements already defined in a standardized terminology and (2) defining those salient terms with indisputable semantics (meanings). The goal of this document is to provide a first subset of the common data dictionary by which AM data may be collected, curated, and shared, regardless of which technology platform and software are used for data storage and exchange.

1.3 The common data dictionary also specifies a way to group AM data pedigree into fifteen information modules pertaining to different aspects of the entire additive manufacturing process.

1.4 The common data dictionary approach specifies data element names that serve to uniquely identify the AM data elements. The data type, value domain, and term definition for each data element are also specified in this practice. References are provided for those data elements with established definitions in existing standards.

1.5 The data elements identified in this common data dictionary are considered essential, because they are most frequently encountered in AM, process agnostic and technology independent. They are broadly applicable to all the process categories defined in ISO/ASTM 52900. It is intended to be a starting point, not all-encompassing.

1.6 The common data dictionary does not specify:

1.6.1 A complete set of data items to be exchanged through AM development lifecycle and value chains.

1.6.2 A minimum set of data items to be exchanged for AM lifecycle and value chain activities.

1.6.3 A common AM data exchange format.

1.6.4 The details associated with how the common descriptions of data items should be implemented for the development of new data systems or data federations among heterogeneous data systems.

1.7 Additional data elements beyond those defined in existing ASTM, ISO, AWS, NASA and SAE standards have been introduced to provide increased utility for AM. These new data items are generally common-sense and frequently used in the AM industry.

Deposition typically occurs either under inert gas (arc systems or laser) or in vacuum (EB systems). Although these are the predominant methods employed in practice, the use of other energy sources, feedstocks and atmospheres may also fall into this category.
