ArcelorMittal collaborates with HP on the additive manufacturing of steel

The world's largest steel company and HP are entering into a strategic collaboration to advance the additive manufacturing of steel. The ArcelorMittal research center will be used as an incubator to develop new applications in collaboration with customers using HP's binder jetting technology and ArcelorMittal's steel powder.

ArcelorMittal acknowledges HP’s technical expertise by selecting their cutting-edge Metal Jet S100 technology to develop steel additive manufacturing. This adoption underscores ArcelorMittal's commitment to leveraging advanced technologies to enhance its manufacturing capabilities.
HP credits ArcelorMittal with promising results with their steel powders, demonstrating robustness for the binder jetting technology. These powders have shown immediate good performance without changing printing parameters, highlighting the synergy between the two companies.
By combining HP’s expertise in printing and existing production in additive manufacturing with ArcelorMittal’s leadership in sustainable steel solutions, the collaboration aims to promote steel additive manufacturing. The collaboration will focus on the key pillars lower cost per part and extended material options.
Lower Cost per Part: Adopting a holistic approach to unlock a range of accessible parts for 3D printing, particularly in the automotive sector.
Extend Material Options: Developing steels with unmatched properties that are impossible with conventional manufacturing.
The proposed working model involves HP and ArcelorMittal collaborating to bring new steel solutions to a sufficient Technology Readiness Level (TRL) and then leveraging ArcelorMittal Research Center for breakthrough applications as an incubator for new applications developed in collaboration with customers, saving them the initial investment to evaluate and qualify the technology until the process can be transferred to a contract manufacturer for final industrialization and production.
ArcelorMittal announced its entry into the additive manufacturing market as a supplier of steel powder a year ago. The company has since built an industrial-scale inert gas atomizer in Aviles, Spain, to produce steel powder for AM technologies such as Laser Powder Bed Fusion (LPBF), Binder Jetting (BJ) and Direct Energy Deposition (DED). The atomizer, with a production capacity of 200 kg to 3 tons, has an initial annual capacity of 1000 tons.
