MX3D Becomes World's First WAAM Additive Manufacturing Facility to Achieve DNV AMC3 Highest-Level Certification

2026-10-05 · Impact score: 60

Amsterdam-based MX3D has announced that it is the world's first wire arc additive manufacturing (WAAM) facility to receive DNV's Additive Manufacturing Criticality Level 3 (AMC3) certification. AMC3 is the highest level awarded by DNV, granted under the DNV-ST-B203 standard (Specification for Additive Manufacturing of Metal Components), qualifying MX3D to produce highly critical metal parts for the maritime, defense, and energy sectors. The certification covers MX3D's robotic additive manufacturing system and its proprietary MetalXL software, verifying that it can consistently deliver critical components suitable for high-load structures where failure is not permitted, with validated materials, quality control, and process consistency. WAAM (also known as DED-Arc, directed energy deposition-arc) uses an electric arc to melt metal wire and build large parts layer by layer, with a robotic arm whose working envelope far exceeds most powder bed systems. Sastry Kandukuri, DNV's Global Practice Lead for Additive Manufacturing, confirmed that no other company has currently reached this level in this technology. The article also mentions that Mencast Marine's fully additively manufactured propeller has received dual classification society certification, signaling that the industry focus is shifting from "can it pass inspection?" to "who can deliver at scale?" Value for powder buyers: ① WAAM/DED-Arc is primarily wire-based, so direct demand for metal powder is limited; ② however, this certification breakthrough establishes a path for arc-based additive manufacturing to replace forging/casting, which will accelerate the adoption of additive manufacturing for large metal components and indirectly expand the overall metal additive manufacturing materials market; ③ suppliers offering both wire and powder should watch for spillover opportunities from similar classification society/industry certification pathways.

MX3D成为全球首家获DNV AMC3最高等级认证的WAAM增材制造工厂

阿姆斯特丹MX3D宣布成为全球首家获得DNV增材制造关键度3级（AMC3）认证的电弧增材制造（WAAM）工厂。AMC3是DNV颁发的最高等级，依据DNV-ST-B203标准（金属零部件增材制造规范）授予，使MX3D具备为海事、国防、能源领域生产高关键性金属部件的资质。认证覆盖MX3D的机器人增材制造系统与自研MetalXL软件，验证其在材料验证、质量控制与工艺一致性上可稳定产出适用于高载荷结构、不容许失效的关键部件。WAAM（又称DED-Arc定向能量沉积-电弧）以电弧熔化金属丝材逐层构建大尺寸零件，机器人臂作业范围远超多数粉末床设备。 DNV增材制造全球实践负责人Sastry Kandukuri确认目前没有其他企业在该技术上达到此等级。文章同时提到Mencast Marine的全增材制造螺旋桨获得船级社双认证，行业焦点正从「能否通过检验」转向「谁能规模化交付」。对粉末采购商的价值：① WAAM/DED-Arc以丝材为主，对金属粉末的直接需求有限；② 但认证突破确立电弧增材替代锻造/铸造的通道，将加速大尺寸金属部件增材化，间接扩大金属增材制造整体材料市场；③ 对丝粉并举的供应商，可关注同类船级社/行业认证路径的溢出机会。

Beam Shaping in LPBF of IN718: Top-Surface Morphology and Defect Mechanisms — Doubling Build Rate via Small Hatch Spacing and High Scan Speed Process Window

Robin Prudlik, Jonas Grünewald, Simon Sankaré, and Katrin Wudy from the Laser Additive Manufacturing team at the Technical University of Munich published a paper in Additive Manufacturing (October 2026 issue, DOI: 10.1016/j.addma.2026.105402) systematically investigating the effects of laser power, scan speed, and hatch spacing on the top-surface morphology and defect formation in IN718 processed by laser powder bed fusion (PBF-LB/M), comparing Gaussian and ring beam profiles. The study shows that surface tension-driven melt pool instability is the core factor limiting productivity, particularly at high scan speeds (≳1600 mm/s) and large hatch spacings (≳0.15 mm). Hatch spacing is the primary trigger of surface irregularity, acting through control of inter-track remelting and transverse melt pool confinement; scan speed determines the morphology type and characteristic wavelength. Increasing hatch spacing reduces inter-track overlap, suppresses remelting-induced planarization, and induces unstable surface features; increasing scan speed shrinks the melt pool size, driving the surface from continuous to discontinuous states. Using ISO 25178 areal roughness parameters and a regularized classification framework, process maps were constructed: a planar top surface is achieved only at small hatch spacings, independent of beam shape; however, the combination of small hatch spacing and high scan speed maintains a planar top surface while increasing build rate by more than twofold compared to typical existing processes. Value for powder buyers: This study provides a new process window for IN718 powder under beam-shaping processes that balances surface quality and productivity. The small hatch spacing and high scan speed strategy imposes higher demands on powder batch consistency—sphericity, particle size distribution, and flowability directly affect melt pool stability at high scan speeds. When purchasing, verify the supplier's batch data and quality traceability documentation.

Guangdong Hengtai's RMB 3.837 Billion Titanium-Based New Materials Integrated Project Phase I Filed: 100,000 t/y Chloride-Process Titanium Dioxide + 25,000 t/y Titanium Sponge

The Phase I green titanium-based new materials integrated project of Guangdong Hengtai New Materials Co., Ltd. completed filing on October 16, 2026, with a total investment of RMB 3.837 billion. It involves building production lines for 100,000 t/y chloride-process titanium dioxide and 25,000 t/y titanium sponge, and is located in the West Zone of Maoming High-tech Industrial Development Zone. This is an upstream titanium raw material capacity expansion rather than a direct additive manufacturing event: titanium sponge is the most upstream feedstock for titanium alloy powders (TC4/TA15, etc.), and the integrated layout of chloride-process titanium dioxide and titanium sponge can dilute titanium raw material costs. The commissioning of 25,000 t/y of titanium sponge capacity will strengthen titanium raw material supply in South China, provide a cost anchor and supply assurance for downstream powder producers, and indirectly benefit the cost and delivery stability of titanium alloy powders. For powder buyers: upstream titanium sponge capacity expansion is a medium- to long-term bullish signal for titanium alloy powder prices; attention should be paid to the linkage between powder production capacity in South China and raw material procurement rhythms.

Titomic Awarded $250,000 Contract by Bechtel BPMI: TKF Cold Spray Technology to Evaluate U.S. Navy Submarine Repair Materials

Titomic USA (ASX: TTT) announced on October 16 that it has been awarded a contract by Bechtel Plant Machinery, Inc. (BPMI) to evaluate and develop advanced material solutions supporting the U.S. Navy submarine industrial base, with an initial order valued at $250,000 (approximately AUD 361,000). The collaboration centers on Titomic's proprietary TKF™ (Titomic Kinetic Fusion) cold spray additive manufacturing technology, which uses solid-state metal powder deposition (without melting) to achieve high-performance coatings, repairs, and near-net-shape components with minimal heat-affected zones and preserved material properties. The two parties will jointly explore advanced repair materials and manufacturing processes for future U.S. Navy programs, including submarine repair. Titomic plans to further introduce the TKF cold spray process into broader defense applications such as rapid production, component repair, and advanced material development to enhance readiness and reduce lifecycle costs. The announcement was made from Huntsville, Alabama, USA. CEO Jim Simpson stated that the future belongs to companies that dare to challenge traditional manufacturing methods and co-develop entirely new capabilities. Previously in an exploratory collaboration phase, this contract marks a substantive advancement of the partnership. Value to powder buyers: ① The defense repair demand signal for spherical metal powders (titanium, aluminum, nickel-based, refractory metals, DED/cold spray feed-grade particle sizes) is strengthening; ② if the U.S. submarine industrial base repair material evaluation is successful, it will bring opportunities for supporting powder supply and qualification; ③ Titomic's deeper integration into the U.S. defense supply chain benefits long-term order expectations for its partner powder suppliers.
