DNV publishes a new edition of the DNV-ST-B203 standard for metal 3D printing

DNV, a provider of risk management and assurance services and one of the leading standards setters focusing on additive manufacturing, has published a new edition of the DNV-ST-B203 standard for 3D printing of metal parts. The standard, which is the result of a joint industry project, covers the basic requirements for the most recognized metal 3D printing technologies and describes new concepts for quality assurance in the area of digital data-driven manufacturing.

Additive manufacturing offers not only a specific manufacturing technique, with new and unique design requirements, but also a potential solution to supply chain challenges by enabling local production in a global market. 3D printing allows you to digitally store 3D models of spare parts on a server and distribute them over the Internet – instead of physically producing them in stock and storing them in warehouses.

The new edition of the DNV-ST-B203 standard includes qualification and production requirements for three new metal 3D printing technologies that complement two others previously published in the first edition. The new edition contains rules on methods:

• targeted energy deposition by electric arc and laser beam (DED-arc and DED-LB)
• fusion in the powder bed using a laser and electron beam (PBF-LB and PBF-EB)
• Binder Jetting

In addition, the DNV-ST-B203 standard contains all requirements for the qualification of combined production methods, such as 3D printing characteristics and defined acceptance criteria for non-destructive testing. The standard also includes new guidance on the definition of families of parts that can extend the validity of qualifications. Added new Criticality Class (AMC) selection guidelines that can help end-users choose the right level of quality assurance for their application, as well as unconventional in-process control and monitoring techniques that can help manufacturers improve efficiency and quality and increase additive manufacturing design freedom .

The standard created by DNV was the first globally accepted standard for the production and use of high-quality additively manufactured metal parts for the oil, gas, marine and energy industries. The new edition was created as part of a joint industry project (JIP) led by the DNV Technology Center in Oslo.
