Introduction
Additive Manufacturing (AM) processes follow many of the same manufacturing steps observed in more
“traditional” manufacturing processes, from design to manufacture to inspection. As an advanced
manufacturing process, AM introduces additional complexities to those steps within an AM workflow
(Illustrated in Figure 1). AM-specific information is necessary to specify, verify, and archive data related to
parts that are manufactured using AM technologies. Key information associated with those steps includes
relevant facility, operator, machine, process, material, postprocess, inspection and other information (see
ASTM F3490).
[1]
Figure 1 — Illustrative additive manufacturing workflow .
This document is developed on the premise that an overarching digital thread can represent the workflow
of a part fabricated using an AM process, such as shown in Figure 1. This digital thread is comprised of the
information requirements designed, procured, manufactured, and inspected. By identifying and selecting
specific information requirements from the digital thread (Figure 2), a data package for a specific part can
be developed for a specific application or scenario associated with each individual stage of the workflow.
Data packages serve to provide an organization with a means to specify and organize part information
requirements specific to a given application or scenario.

This document is developed to maximize an organization’s flexibility when determining its data package
requirements for various scenarios. The modularization of information requirements and their level of
specificity supports the general, broad adoption of this document while also supporting specific organization
needs and scenario requirements. In this sense, this document uses modular, multi-tiered information
requirements to support the development of data packages for various scenarios with varying levels of
control. Configuration management practices are used to identify acceptable representations, including file
formats and file types, for given data package requirements.
To support part acceptance, this document is developed on the premise that data package requirements,
working in concert with configuration management, can be used to create a digital representation, or a
“digital twin” of an additively manufactured part. A digital twin (Figure 3) is developed by addressing the
requirements of this document for a specific part and application scenario.
Figure 3 — The data package concept is central to the curation of additive manufacturing
information.
In transitioning from a design to a manufactured part, the AM digital thread progresses through many
digital representations including: CAD design, simulation, tessellated geometry; sliced geometry; build file;
part with build data; and part with evaluation data. At each of these stages, the digital provenance of the
part is evolving, with its digital twin maturing from the generation of new data at every stage. As a digital
representation of the intended physical counterpart, the digital twin provides important insight into the
state of the part through its design to product transformation. When accepting a final part, it is important
to have confidence in the processes used in the fabrication of the part, since differences in implementation
can mean different parts. The digital twin provides an important resource from which confidence can be
gained but can create its own uncertainty if not well-defined and well-understood, with the requirements
identified in the data package.
Clause 4 outlines the general procedure to be followed for an organization to develop a customized data
package, from identifying information requirements to adopting configuration management practices.
Clauses from 5 to 10 outline the data requirements across the AM workflow. Clause 10 provides the specific
configurations to meet specified organizational requirements.
Key concepts used and discussed in this document include: data package; data package requirement; digital
thread; digital twin; modular components; configurability; configuration management; capability (software,
equipment, facility, operator), criticality (part or application).

Additive Manufacturing — Data — Data packages for AM parts
1 Scope
This document provides the methods, parameter sets and models to develop and utilize a data package for
a part created using AM technologies (AM part). This document is scoped to the information requirements
associated with workflow of the fabrication of an AM part, from design to acceptance. Peripheral
information related to entities such as organization, facility, operator, security, and others is addressed for
sake of completeness; but is not the focus of this document and can be defined elsewhere. This document
provides the means to develop an organizational or application-specific data package for the communication
between and amongst the designer, the manufacturer, and all acceptance authorities, among other potential
stakeholders.
This document does not impose a plan of execution to produce an AM part, though a digital thread is
provided to establish a referenceable information workflow.
The requirements set forth in this document are based on the fabrication of a part using the PBF-LB/M
(Powder Bed Fusion- Laser Based/ Metal) process. While specific details directly relate to PBF-LB/M,
generalized workflow requirements can be related to any AM process.

4 Significance and use
Part design, manufacture, inspection, and procurement can be relatively complex when AM processes
are used. Complexities of AM processes can create variabilities in AM parts; therefore, the specification
of additional process and workflow information is desired at times. Variabilities in AM processes and
workflows create challenges in the common specification interpretations of AM processes. This document
provides the methods, supported by a reference workflow and information flow, on which AM parts can be
consistently specified and interpreted for part design, manufacture, inspection, and procurement.
Additive manufacturing workflows come in varying levels of complexity, and the processes can be controlled
and specified at varying levels of detail. When adopting AM processes, explicit communication is vital to
satisfy organization objectives. Data packages provide an organization(s) with the means for communicating
details about a part or a design. Under-specification can lead to loss of fidelity in the fabrication of AM parts,
while overspecification can lead to improper execution by underqualified personnel. Identifying the correct
requirements at the proper level of specificity is essential to successful delivery and acquisition of AM parts.
This document facilitates the identification of individual and subsets of information requirements across this
workflow to communicate desired levels of provenance for a given application or scenario. The information
requirements set forth at each workflow stage are only imposed when a specific data-package configuration
has been called into place. An organization shall identify a specific data package and configuration-
management plan to specify how selected requirements are to be met for a given application or scenario.
This document uses the concept of modularity to support various scenarios in which a data package can be
required. The requirements put forth by individual modules may not be inclusive, and these modules can be
extended and adopted as the organization sees fit. Different combinations of modules can be developed to
satisfy various application scenarios as outlined in Clause 11. Different levels of control within each set of
requirements can be specified based on capabilities of relevant organizations and individuals, as detailed in
Clause 11.
This document supplements existing data package practices with AM-specific considerations and does
not support requirements that can be put in place by an organization for parts manufactured with other
manufacturing processes; nor does it replace other standards that can be used to satisfy data package
requirements of non-additively manufactured parts. This document will leverage and reference existing
standards where appropriate.

This document leverages the concept of a “digital twin” for completeness to relate the digital thread, data
packages, and configuration management. Digital twin is not a focus of this standard, however, and thus
development of one is not required to meet outlined specifications.
5 Method for data package development
5.1 General
The method for creating an AM data package consists of 5 separate steps. This clause provides the necessary
guidance to create a customized data package to meet specific organizational or application requirements.
1. Identifying application scenario and associated data package requirements
2. Using modules for data package configuration
3. Determining level of specificity by setting requirements control
4. Establishing configuration management practices
5. Creating a data package
These steps are detailed in the following subclauses.
5.2 Identifying the application scenario and associated data package requirements
Depending on the scenario or application that a data package is being developed for, the requirements can
vary significantly. Therefore, the configuration of data packages will depend on the context for which they
are being developed. This context can be one of three data package application scenarios:
— Acquisition - This scenario occurs when an AM part is to be sourced from an outside party to meet a
pre-existing specification and the acquiring organization has a need to communicate specifics about the
design, fabrication, and testing of the AM part to the outside party.
— Manufacture in house - The scenario occurs when an AM part is to be fabricated within an organization
and communication between design, manufacture, testing, and acceptance is needed.
— Verification only - This scenario occurs when an AM part faces unique acceptance requirements (either
in house or external) but no further design or process communication is needed.
The three scenarios are further delineated based on the use history of the part to be fabricated:
— Prototype - This scenario occurs when a part is still progressing through design and manufacturing
iterations and final specifications have not yet been determined.
— New part- This scenario occurs when a fully documented version of the AM part does not exist, and the
part is being fabricated to specifications for the first time.
— Existing part - This scenario occurs when full specifications for the fabrication of an AM part exist, and
these specifications are to be used in fabrication of additional AM parts.
The three scenarios are further delineated based on the maturity of the part to be fabricated:
— Expeditionary - This scenario occurs when a part is being developed for individual or small use-case
scenarios.
— Developmental - This scenario occurs when an AM part has not yet reached full production status and
additional specifications are needed.
— Production - This scenario occurs when an AM part has fully matured into production status and any
implications associated with its fabrication are well understood and documented.

ISO/ASTM DIS 52951:2025(en)
5.3 Using modules for data package configuration
Once the appropriate scenario has been chosen and effectively delineated, the information elements
associated with the scenario can be identified. These information elements, identified through appropriate
modules, determine what information will be required in the data package configuration.
Clause 11.1 provides suggested configurations of modules for each of the above scenarios in three separate
tables. Users of this document can choose to adopt a suggested configuration or simplify or expand on a
configuration. The final configuration of the data package requirements requires the user to identify the
specific modules to be satisfied (Figure 4).
The data package requirements associated with each module are provided in Table 2 through Table 19.
How requirements are explicitly satisfied must be agreed upon by involved parties, and levels of specificity
allows for adjustments of these requirements (High, Medium, or Low). The provided requirements provide
a baseline for configurable data packages but are not meant to be inclusive. Additional requirements can be
added as needed.
Figure 4 — Configurable “blocks” of data within the AM workflow. Highlighted spaces are examples
[2]
of data package configurations (Adapted from ).
5.4 Determining level of specificity by setting requirements control
The configuration of data package modules depends on the scenario. The specified amount of control will
depend on the criticality of the application scenario and the capability of stakeholders.

© ISO/ASTM International 2025 – All rights reserved
ISO/ASTM DIS 52951:2025(en)
The information requirements within each module are satisfied using a multi-tiered approach to
establishing a level of specificity. Each tier adds an additional layer of specificity necessary to satisfy the
requirements of the data package. This document adopts a three-tier approach: low, medium, and high. High
has the most stringent data requirements, thus providing the most explicit control, while low leaves more
of the implementation up to the performer. The selection of low, medium, or high control is dependent on
assessed capabilities of a performer in respect to stakeholder requirements. This designation is adopted
throughout the data package tables provided in Sections 6-9. As the three tiers are traversed, and new data
requirements are added, the amount of control over each stage increases. Control refers to how much of
the data requirements at each stage are specified and shall be met, as opposed to the relaxation of some
requirements based on the capabilities of the performer. Low control is associated with the least number of
requirements, while High control will specify maximum available requirements.
The amount of control desired for a stage is influenced by two critical factors: criticality and capability.
Highly critical parts will require the highest levels of control, while less critical parts can have less stringent
control requirements. For instance, at the design stage, if the geometry is critical, the designer should have
the most control. However, if geometry requirements can be relaxed, it can be better to let pre-process
performers determine final requirements.
The capability refers to the experience or capacity of the performer. The performer can refer to designer,
operator, technician, or procurement specialist. The capability of the performer can also refer to the quality
and capacity of the performer’s equipment. High-capability performers are expected to have the experience
needed to execute a high level of control over the process. Such performers are expected to follow and meet
all detailed requirements, to provide skilled input, and to meet acceptance requirements with minimal
guidance. Low capability performers can need additional specifications in order to perform their expected
duties, and they should not be asked to play critical roles in the fabrication of critical parts.
Table 1 provides a Part vs Performer capability map, where recommendations are made on the level of
guidance, or control, that should be expected based on the criticality of the part and the capability of the
performer(s).
Table 1 — Part vs Performer capability maps the level of control to the criticality of the parts and
the capability of the performers.

Capabilities are considered as:
High capability: Expertise is possessed in by the individual or organization responsible for manufacturing
the final part. High Capability implies that the performer has the ability to meet designated requirements
and has access to all necessary equipment and information to do so.
Low capability: Familiarity with AM processes is present, but the performer can possibly not have the
knowledge or experience needed to execute to the highest levels. Some equipment is available to the
performer, but stringent requirements cannot be met.
High control: The design and manufacture of the part has been developed under careful consideration. The
performer shall meet detailed part, process, and inspection requirements in order for any deliverable to be
deemed acceptable.
© ISO/ASTM International 2025 – All rights reserved
ISO/ASTM DIS 52951:2025(en)
Low control: The design of the part is of utmost importance, but the manufacture of the part is left
primarily to the performer. The expectation is that the performer will have the capability and know how to
manufacture the part to meet design and performance requirements without explicit instructions.
High risk: Generally, this implies that failure to meet any part requirement can result in catastrophic failure.
Risk levels are to be determined by the organization.
Low risk: Generally, this implies that failure to meet one or more part requirements can still result in a
serviceable part. Such failures can lead to inconveniences that can be overcome with replacement parts or
with sub-optimal performance. Risk levels are to be determined by the organization.
5.5 Establishing configuration management practices
Configuration-management techniques are required to control and manage data within the AM production
cycle, effectively constructing a digital twin. As a physical AM part traverses this lifecycle, the associated
digital twin will undergo many digital transformations that mirror the various lifecycle functions - from a
raw design to a qualified product. Configuration management begins early in the product design phase and
aims at ensuring that the design intent is realized by monitoring and controlling the subsequent processes.
A configuration management plan:
— Defines the allowable representations on which requirements can be met.
— Identifies allowable formats and configurations.
— Establishes consistency in how data are captured and represented.
— Provides consistent evaluation and qualification across AM part families.
The application of configuration management shall aim at reducing impermissible and unintended changes
and monitor/record the permissible changes. For example, increasing the component wall thicknesses in the
CAD (Computer-Aided Design) digital twin to compensate for material removal in post-processing stages
can potentially disrupt an AM part’s definition. Format changes, such as converting the CAD digital twin
into an AM machine-readable format, is another process-driven modification that can influence the design
intent of the component. Since such examples can influence the design intent of the component, they should
be managed carefully. Figure 5 outlines a scenario where a configuration plan is iterated through.

Configuration management practices should be outlined as a configuration management plan. Configuration
management for AM should be planned during the earliest project stage. Procedures should be developed for
managing the configuration of the design and relevant data through to its disposal. Additional considerations
should be made for configuration between organizations to ensure each organisation’s approach and coding
schemes are consistent and compatible. Configuration management plans should make the following
considerations:
— Configuration identification - Identification of Configuration Items (CI) requires the knowledge of
which items influence the integrity of the component data as well as which data items are required for
compliance consistency. All CIs and associated AM formats should be assigned an identifier and revision
controlled.
— Configuration control (Process required to change a CI and re-baseline it) - Configuration
control can be defined as “a systematic process that ensures that changes to released configuration
documentation are properly identified, documented, evaluated for impact, approved by an appropriate
[3]
level of authority, incorporated, and verified” . In documenting a CI change, critical information to be
captured includes the nature of the configuration change, the identification of previous and current
states of the configuration item, and any data transformation and losses.
— Configuration status accounting (Traceability) - The configuration data shall be stored in a system
that allows for configuration status retrievals. This allows for the component’s full digital twin to be
accessed when required anywhere along its digital thread.
— Configuration verification and audit - Configuration baselines need to be periodically audited to
verify their contents and ensure conformance. This involves a functional and physical verification of the
component configuration.
Configuration-management standards and handbooks such as SAE EIA-649, ISO 10007 and MIL-HDBK-61B
define the configuration management process in five key functions as depicted in Figure 6. Annex C provides
an example of a configuration management scenario.

5.6 Creating a data package
Upon completing steps 1 to 4, the content of the data package is ready to be finalized. Finalization of the data
package can require additional considerations (beyond steps 1 to 4) to construct realizable requirements for

the implementation of a data package. In determining what, if any, additional considerations are necessary,
the following steps should be considered:
a) Ensuring proper module configuration and level of specificity for identified scenario,
b) Confirming information leveraged in determining the data package requirements aligns with
established workflow,
c) Recognizing how this information is represented in the digital thread and identifying acceptable data
format types in a configuration management plan,
d) Establishing specific data requirements based on confirmed data package requirements, and
e) Communicating requirements or datasets through explicit mapping to modules and configuration
management plan.
Application of this approach results in data packages that can incorporate multiple production phases and
workflow stages to specify and meet data package requirements. It shall be noted that the extent to which
configuration management is leveraged is dependent on the production application and scenario. Certain
application scenarios can require multiple qualification phases and versions, while others only require one.
Clause 12 provides a template on which data package requirements can be communicated. When a data
package is successfully created, communication of the data package can vary based on organizational
implementations but the interpretation of the requirements will remain consistent.
When implementing a data package for acceptance, the resulting digital twins and corresponding digital
thread shall accurately provide full digital traceability and record of the AM product. In quality control
for additive manufacturing, establishing this digital provenance has become a necessary part of the part
qualification process.
