F42.04 - Design

SCOPE
1.1 This document provides guidance to designers who are considering the use of metal Laser Powder Bed Fusion (PBF-LB) method for their products. This guide outlines the following post-processing operations that can be considered after completion of a build on a metal additive manufacturing system:  
1.1.1 Powder removal,  
1.1.2 Thermal post-processing,  
1.1.3 Build platform removal,  
1.1.4 Support removal,  
1.1.5 Machining, and  
1.1.6 Surface finishing.  
1.2 The topics of non-destructive testing (NDT) and inspection are beyond the scope of this document as it requires a comprehensive guide in its own right. Also, outside the scope are other metal PBF processes such as powder bed fusion – electron beam (PBF-EB) and hybrid additive manufacturing (methods combining additive manufacturing and subtractive manufacturing technologies in a single machine).  
1.3 With respect to existing ISO/ASTM standards, this guide is positioned between ISO/ASTM 52910 and process-specific design guidelines such as ISO/ASTM 52911-1.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 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.

SCOPE
1.1 This document specifies the features of MEX/P and provides detailed design recommendations.  
1.2 Some of the fundamental principles are also applicable to other AM processes, provided that due consideration is given to process-specific features.  
1.3 This document also provides a state of the art review of design guidelines associated with the MEX/P by bringing together relevant knowledge about this process and by supplementing the scope of ISO/ASTM 52910.  
1.4 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.

ABSTRACT
This specification provides a framework for an interchange format to address the current and future needs of the additive manufacturing technology. The additive manufacturing file (AMF) may be prepared, displayed, and transmitted on paper or electronically, provided the requirements presented in this specification are met. When prepared in a structured electronic format, strict adherence to an extensible markup language (XML) schema is required to support standards-compliant interoperability.
SCOPE
1.1 This document provides the specification for the Additive Manufacturing File Format (AMF), an interchange format to address the current and future needs of additive manufacturing technology.  
1.2 This document specifies the requirements for the preparation, display and transmission for the AMF. When prepared in a structured electronic format, strict adherence to an extensible markup language (XML)(1)2 schema supports standards-compliant interoperability.
Note 1: A W3C XML schema definition (XSD) for the AMF is available from ISO from http://standards.iso.org/iso/52915 and from ASTM from www.astm.org/MEETINGS/images/amf.xsd. An implementation guide for such an XML schema is provided in Annex A1.  
1.3 It is recognized that there is additional information relevant to the final part that is not covered by the current version of this document. Suggested future features are listed in Annex A2.  
1.4 This document does not specify any explicit mechanisms for ensuring data integrity, electronic signatures and encryptions.

SCOPE
1.1 This document specifies the features of Directed Energy Deposition (DED) and provides detailed design recommendations. This document also provides a state-of-the-art review of design guidelines associated with the use of DED by bringing together relevant knowledge about this process and by extending the scope of ISO/ASTM 52910.
Some of the fundamental principles are also applicable to other additive manufacturing (AM) processes, provided that due consideration is given to process-specific features.  
1.2 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.

SCOPE
1.1 This document gives guidelines and best practices for using additive manufacturing (AM) in product design.  
1.2 It is applicable during the design of all types of products, devices, systems, components, or parts that are fabricated by any type of AM system. These guidelines help determine which design considerations can be utilized in a design project or that can be utilized to take advantage of the capabilities of an AM process.  
1.3 General guidance and identification of issues are supported, but specific design solutions and process-specific or material-specific data are not supported. The intended audience comprises three types of users:  
1.3.1 designers who are designing products to be fabricated in an AM system and their managers,  
1.3.2 students who are learning mechanical design and computer-aided design,  
1.3.3 developers of AM design guidelines and design guidance systems.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SCOPE
1.1 This specification describes a framework for an interchange format to address the current and future needs of
additive manufacturing technology. For the last three decades, the STL file format has been the industry standard for transferring information between design programs and additive manufacturing equipment. An STL file contains information only about a surface mesh and has no provisions for representing color, texture, material, substructure, and other properties of the fabricated target object. As additive manufacturing technology is quickly evolving from producing primarily single-material, homogenous shapes to producing multimaterial geometries in full color with functionally graded materials and microstructures, there is a growing need for a standard interchange file format that can support these features.
1.2 The additive manufacturing file (AMF) may be prepared, displayed, and transmitted on paper or electronically, provided the information required by this specification is included. When prepared in a structured electronic format, strict adherence to an extensible markup language (XML)schema is required to support standards-compliant interoperability. The adjunct to this specification contains a W3C XML schema and Annex A1 contains an implementation guide for such representation.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.4 This standard also does not purport to address any copyright and intellectual property concerns, if any, associated with its use. It is the responsibility of the user of this standard to meet any intellectual property regulations on the use of information encoded in this file format.
