Meltio 在 Formnext 2026 展示线激光金属3D打印汽车零部件
Meltio Showcases Metal 3D-Printed Automotive Components at Formnext 2026
Meltio 在 Formnext 2026 展会上展示其线激光金属3D打印技术的实际应用，包括由 DMZ 开发、装在 Abarth 595 跑车上的高性能排气歧管。该不锈钢部件已路试约 10,000 公里，其中 600 公里在赛道完成，一年使用后仍保持原始状态。借助 Meltio 的定向能量沉积（DED）技术，DMZ 将装配时间从 8 小时缩短至 1 小时。另一项汽车应用是通过在选定区域增材沉积金属来强化钢制车轮，在保留重量优势的同时提高刚度，使设计达到与合金轮相同的固有频率。在工业维护方面，IMET3D 在关键离心泵失效后，用线激光金属3D打印以不锈钢 316L 重新设计并制造了已停产部件的替代件，耐腐蚀性较原铸铁设计显著提升，避免了更换整个系统。Meltio 展位号为 12.0 C119，现场展示多个金属部件及实时打印演示，应用覆盖汽车、国防、采矿、油气、造船和航空航天等领域。
Meltio is showcasing real-world applications of its wire-laser metal 3D-printing technology at Formnext 2026, including a high-performance exhaust header developed by DMZ and installed in an Abarth 595 sports car. The component has completed approximately 10,000 kilometres on the road, including 600 kilometres on a race track, demonstrating the application of metal additive manufacturing in automotive engineering.
Visitors to Meltio’s booth, 12.0 C119, can see several metal components produced using the company’s technology, alongside live printing demonstrations. The showcased applications cover automotive, defence, mining, oil and gas, shipbuilding and aerospace, among other industries, where the technology is being used to manufacture and repair metal parts.
The DMZ exhaust header demonstrates how additive manufacturing can support complex component design while reducing production time. Developed to withstand high temperatures and mechanical stresses, the stainless-steel component features geometries designed to optimise exhaust gas flow in a combustion engine. Using Meltio’s directed energy deposition (DED) technology, DMZ reduced assembly time from eight hours to one hour. The exhaust system was installed in an Abarth 595 and tested over approximately 10,000 kilometres during a year of use, retaining its original condition.
Another automotive application involves reinforcing steel car wheels through the deposition of additional metal in selected areas. DMZ used Meltio’s technology to increase the stiffness of the steel wheel while retaining its weight advantage. The resulting design achieved the same natural frequency as an alloy wheel, combining improved structural performance with lower weight.
Meltio’s technology is also being used to address industrial maintenance challenges. In one application, IMET3D produced a replacement for an obsolete component after the failure of a critical centrifugal pump. Instead of replacing the entire system, the industrial customer used wire-laser metal 3D printing to recover the component through additive manufacturing.
The part was redesigned and manufactured by Meltio in stainless steel 316L, offering significantly improved corrosion resistance compared with the original cast-iron design. The approach enabled the recovery of an industrial asset when conventional spare parts were no longer available.
These applications demonstrate the use of wire-laser metal additive manufacturing for component production, design optimisation and repair. By enabling complex geometries, shorter manufacturing cycles and the local recovery of equipment, Meltio’s technology provides manufacturers and industrial operators with an alternative approach to metal part manufacturing and maintenance.
