Thematic session on Additive Manufacturing

Date and time

16:30-18:0010 November 2026

Location

Room W and Zoom - Hybrid

Additive manufacturing is a process of joining materials to make parts from 3D model data, usually layer upon layer. It has developed from a prototyping tool into an industrial-scale manufacturing platform and is increasingly used alongside digital and data-enabled technologies. Its growing use can create opportunities for greater flexibility and scalability in manufacturing, as well as for increasing reparability, refurbishing and remanufacturing of materials, contributing to a more circular economy.

Standards and technical regulations can play an important role in supporting the development and use of additive manufacturing across markets.

This session will explore the current landscape of standards and regulations for additive manufacturing as well as Members' practical experiences and best practices. Discussions may consider how the principles of TBT Agreement can facilitate trade and innovation and support sustainable manufacturing and circular economy approaches. The session may also highlight areas where regulatory cooperation and coordination with relevant WTO and international bodies can add value.

Preliminary guiding questions:

· What opportunities and challenges arise in developing and applying standards, technical regulations and conformity assessment procedures for additive manufacturing?

· How can the principles of TBT Agreement help to ensure that TBT measures related to additive manufacturing support resource and material efficiency, waste reduction, circularity and environmental performance across the product life cycle, while encouraging trade and innovation?

· What approaches and good practices can help standards and technical regulations for additive manufacturing facilitate trade and innovation, including for inputs and machinery and in relation to digital design and data interoperability?

· How could greater cooperation among Members, and closer coordination among relevant WTO bodies and other international bodies, help address regulatory challenges related to additive manufacturing?

Dr. Mohsen Seifi is Vice President of the Critical and Emerging Technologies (CET) Division at ASTM International, where he leads standards programs in advanced manufacturing, robotics and autonomous systems, uncrewed aircraft systems, and commercial space, with artificial intelligence running across all of them. He directs a team based across four continents and works regularly with government agencies, regulators, and international standards bodies on how consensus standards are applied in qualification, certification, and regulation. He launched ASTM's Additive Manufacturing Center of Excellence in 2018 and has worked for more than a decade within the joint ISO/ASTM standards framework for additive manufacturing that industry and regulators now qualify against worldwide. He is Principal Investigator of the ASCET Center of Excellence, a cooperative agreement between ASTM International and the U.S. National Institute of Standards and Technology on international standardization for critical and emerging technologies, and chairs the ASTM International Conference on Advanced Manufacturing (ICAM). A materials scientist by training, he holds a Ph.D. from Case Western Reserve University.

Hu Juan is a senior engineer at the National Center of Inspection on Additive Manufacturing Products Quality (JIANGSU), postdoctoral Research Fellow at Nanjing University of Aeronautics and Astronautics. Specializing in additive manufacturing testing, certification and standardization, she concentrates on AM-specific inspection methods development and quality ev_aluation system construction as well as standardization work. She has organized nearly 20 national standards and four English-language editions of national standards development. These standards harmonize national test methods, reduce testing costs, underpin product acceptance and facilitate global market access for Chinese products. She is a registered expert for ASTM F42 and ISO/TC 261 WG3 and served as a secretary of the Test Method Subcommittee of the National Additive Manufacturing Standardization Technical Committee.
