The Amsterdam robotic metal printing company is the first in the world to hold DNV’s highest additive manufacturing classification for wire arc additive manufacturing, clearing its parts for critical, high-load structural use.

Amsterdam-based MX3D has received a DNV Certificate of Qualification at the AMC3 level for its wire arc additive manufacturing (WAAM) facility, making it the first company in the world to reach that level for the technology. The certificate was issued under DNV-ST-B203, DNV’s standard for the additive manufacturing of metallic parts, and was announced on September 30.
MX3D builds large metal parts by depositing weld wire layer by layer with industrial robots, a process also known as DED-Arc. The company sells turnkey robotic WAAM cells and prints parts for the maritime, energy, defense and nuclear sectors. Founded in 2014, it is still best known for the stainless steel pedestrian bridge it printed for Amsterdam’s city center.
What AMC3 Means
AMC3, short for Additive Manufacturing Criticality 3, is the highest of the criticality classes DNV defines for printed components. It covers parts used in critical, high-load structural applications, the territory that has so far belonged to forgings and castings. To qualify, MX3D’s facility, its MetalXL process software and its WAAM procedures were audited, with the assessment covering mechanical testing, material validation and quality control.
Ready for Critical Parts
MX3D CEO Gijs van der Velden called the certification a milestone for the company and for the WAAM industry as a whole.
This confirms that our technology and processes meet the most stringent quality and safety standards required for producing highly critical metal parts. We have proven that our robotic 3D metal printing technology is not only highly efficient and scalable, but fully ready to serve industries where reliability is non-negotiable.
Gijs van der Velden
CEO, MX3D
DNV’s additive manufacturing lead pointed to the broader adoption picture across the sectors where the classification society is active.
As the first company globally to achieve DNV certification at AMC 3 level for DED-Arc/WAAM technology, MX3D has demonstrated a strong commitment to quality, qualification excellence, and the industrial adoption of additive manufacturing. We look forward to continuing our collaboration as additive manufacturing adoption grows across the energy, maritime, and industrial sectors.

According to MX3D, the certification positions WAAM as a verified alternative to forging and casting for heavy-duty, large-scale metal parts. For engineering teams in regulated sectors, it means a printed part from the Amsterdam facility can now be specified with a DNV qualification behind it, rather than requiring a project-by-project approval.
