Standard Practice for Additive Manufacturing — General Principles — Overview of Data Pedigree

Importancia y uso:

5.1 This standard can be used by AM data-system developers to design or update a database that meets business and process requirements. The information modules provide a foundation for an AM data structure. Standard definitions of data elements, their data types, and allowable values can be used directly to define the attributes for AM databases.

5.2 This standard is intended for organizations and personnel who wish to share AM data or who develop AM data management systems. The information modules defined in this standard represent a primary set of AM concepts. These concepts can be used to develop a common data model and a common data-exchange format, thereby enabling the transfer of data between different AM data management systems. Since legacy AM data management systems may use different data element definitions, translators will be needed to map their proprietary data into the common data exchange format. This common format will support both exporting from and importing to the original native formats.

5.3 This standard serves as the source for creating common definitions of and representations for all the AM data elements that have been agreed-upon by the community. Previously, standard definitions existed for only a few, high-level, data elements. This limited the ability of organizations to share AM data elements that were not included in those standards. Additionally, most commercially available AM data management software applications used each organization’s internally defined data elements, thereby inadvertently hindering the ability to easily share full AM data sets with other organizations’ software solutions.

5.4 This standard significantly eases the communication and use of AM data elements across the industry. It does this by providing, in a single location, a common understanding of individual elements within 15 information modules. Each organization can have increased confidence in using and analyzing AM data sets that adhere to this standard, even when those data sets are generated by another organization. This standard will also provide a starting point from which to build a common data format that will facilitate the transfer of AM data sets among those organizations.

5.5 Not all the data elements are applicable to all the use cases. Some of the definitions of the data items are only applicable to certain cases. For example, “Specimen Orientation” and “Specimen Location” are only applicable to specimens extracted from a built part, not powder specimens.
