MX3D's Amsterdam production facility has received DNV Additive Manufacturing Criticality 3 certification for wire-arc additive manufacturing. In its 30 September 2026 announcement, the company described the site as the first WAAM or DED-Arc facility certified by DNV at this highest criticality level. The development matters because the market for large, load-bearing metal parts needs more than deposition capability: customers must also understand how process, material and deviations are controlled.

What AMC3 means

DNV-ST-B203 provides a framework for procurement and quality assurance of additively manufactured parts. Criticality is selected from the consequence of failure, function and operating environment; AMC3 is the most demanding level for high-consequence applications. Certification is therefore more than machine acceptance. The facility must demonstrate a documented and repeatable production chain.

MX3D says the audit covered the facility, its MetalXL process-control software, WAAM procedures, mechanical testing, material validation and quality control. That scope is important because DED-Arc properties emerge from the combined control of wire, arc energy, toolpath, interpass temperature, shielding gas and post-processing.

What the certificate does not mean

Facility certification does not automatically approve every component made there. A specific part still needs defined requirements, an approved design, material and production records, plus an inspection and acceptance plan matched to its critical function. A new geometry, different wire, materially changed toolpath or different heat treatment may require separate evaluation.

The value of the DNV framework is precisely that it separates organisational capability from product acceptance. A certified facility can reduce part of a customer's supplier-audit burden, provide a common language for the quality plan and improve traceability, but it does not replace engineering responsibility for the component.

Where it may have practical impact

WAAM can compete for large near-net-shape metal preforms, especially where forged or cast stock has long lead times, creates substantial machining waste or is needed only in low quantities. In maritime, energy and defence applications, however, failure consequences are high. Shorter manufacturing time has value only alongside controlled properties, defect criteria and change management.

A buyer's next step should not be limited to requesting a quotation. The AMC class, applicable standard, load cases, machining allowance, non-destructive examination, witness coupons and required data package should be defined up front. Only then can the complete qualified route be compared with a conventional supply chain for lead time and material use.

Verified fact, company claim and conclusion

Verified facts are the announced AMC3 certification, the published scope of DNV-ST-B203 and the audit elements reported by MX3D. The 'world first' wording is a claim from MX3D and trade coverage; LAYERTIMES found no public, comprehensive global certificate database with which to prove it independently. Our conclusion is that the certification is a genuine industrialisation milestone, but its commercial weight will be demonstrated by the number of components that complete documented part-level approval.
