GB/T 37698-2019Additive manufacturing - Design - Requirements, guidelines and recommendations (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafting method to modify the use of ISO /ASTM52910..2018 "additive manufacturing design requirements, guidelines and recommendations."

This standard has more structural adjustments than ISO /ASTM52910.2018. Appendix A lists this standard and ISO /ASTM.

52901 is listed in Chapter 2;

--- Removed the example sentence in 6.7.1 of ISO /ASTM52910.2018 "Similarly, standards for the characteristics of raw materials are being developed, such as

Metal powder for powder bed melting process (see ASTM F3049-14)";

--- Removed the future possible standards in ISO /ASTM52910.2018, 6.7.2.1 and the example sentence "Comprehensive classification of materials"

The standard will be released, and the standard may include some elements of this section. For example, ASTMF3122-14 is an evaluation of additive manufacturing.

Guide to the mechanical properties of metal parts";

--- In the reference, the normative reference document ISO /ASTM52900 referenced in the body has been deleted, adding the text mentioned in the text

Reference standard GB/T 16288.

1 Scope

This standard gives the requirements, guidelines and recommendations for the design of additive manufacturing products.

This standard applies to the design of various products, devices, systems, components or parts manufactured by any additive manufacturing system.

This standard helps determine which design factors are utilized in a design project or which additive manufacturing processes are utilized.

This standard provides guidance on common issues, but does not include specific design, process or material data.

The use of this standard includes the following three categories.

--- Designers of additive manufacturing products and their managers;

--- Students who study mechanical design and computer-aided design;

--- Developer of additive manufacturing design guide and design guidance system.
