DNV has announced updates to its flagship standard for additive manufacturing implementation across the energy and maritime sectors.
The independent organisation, which provides assurances and classifications primarily to those industries, says the new edition of its DNV-ST-B203 standard is now extended to polymer 3D printed parts and introduces critical enhancements in design, sustainability, and qualification.
“With global competition in AM standards, it is crucial to provide a robust, practical framework that builds trust and scalability for this transformative technology,” said Dr. Sastry Kandukuri, Global practice lead for additive manufacturing at DNV. “This edition directly addresses industry needs with practical design rules and clear CO2 footprint metrics, empowering our customers to adopt AM with greater confidence.”
The updated standard now includes:
- A robust qualification framework for polymer parts, ensuring consistency and reliability across material types.
- Practical design guidelines to help engineers optimize part geometry and material selection.
- Guidelines for reporting CO2 footprint: A new methodology enables the estimation of the carbon footprint for AM parts.
- Expanded qualification framework: The process is streamlined to group parts under shared qualifications.
This new edition is one of the outcomes of the ProGRAM Joint Industry Project (JIP) which is focusing on digital inventories and new AM technologies.
Stian Gurrik, Project manager for the ProGRAM JIP commented, “Our projects have already shown a significant environmental benefit from using AM for part repair versus conventional replacement, highlighting the sustainability potential this standard helps to unlock.”
Earlier this year, DNV announced a new framework that aims to ‘transform parts management in the energy sector’ with digital inventories supported by on-demand additive manufacturing. ‘DNV-RP-B205 Digital inventories and on-demand manufacturing’ is designed help to cut costs and improve efficiencies in spare part supply, warehousing and part obsolescence.
