DNV has awarded MX3D an AMC3 certificate, the highest tier in its Additive Manufacturing Criticality scale, making MX3D the first WAAM shop worldwide to hold it. The certificate was issued under DNV-ST-B203, the classification society’s standard for qualifying additive manufacturing facilities and processes.
DNV’s audit covered MX3D’s facility, its MetalXL software, and its wire arc additive manufacturing process, with testing, material validation and quality controls completed before certification. AMC3 sits at the top of DNV’s criticality scale, reserved for parts where failure carries the highest consequence, which is the bracket MX3D is targeting with structural components for maritime, defense and energy customers.
A facility-level certification at this tier is meant to save buyers a separate one-off qualification campaign per job, though DNV’s announcement doesn’t spell out what the certificate actually waives. DNV and MX3D have not published which parts, alloys or load cases fall under the AMC3 scope, or what the audit involved.
DNV’s Sastry Kandukuri, global practice lead for additive manufacturing at the company’s Oslo technology centre, called it the first global AMC3 certification for “DED-Arc/WAAM technology.” MX3D CEO Gijs van der Velden said the certification confirms the company’s “technology and processes meet the most stringent quality and safety standards required for producing highly critical metal parts.”
