Desktop Metal launches steel powder

Desktop Metal has launched 4140 chromoly steel powder for its metal 3D printing system for prototyping and low volume production.

According to the company, 4140 has toughness, high tensile strength, and abrasion and impact resistance, making it a good all-purpose steel for industrial applications. It can be used to print a range of industrial applications, such as couplings, forks, pinions, pump shafts, sprockets, torsion bars, worm gears, connecting rods, and fasteners, Desktop Metal said. It can also print parts for industries such as automotive, oil and gas, pumps and hydraulics, agriculture and defense. ‘It’s well-known in additive manufacturing that the selection of metal materials is limited to a few options for high value-added parts,’ said Dominique Ghiglione, R&D Manager at CETIM, the Technical Centre for Mechanical Industry. ‘The fact that Desktop Metal offers 4140 is excellent news for the mechanical industry. This material is indeed the ‘Swiss army knife’ because of its good performance-to-cost ratio and its mechanical characteristics. This material is found in many automotive components, special machines, construction machinery, agricultural machinery, and so on. CETIM knows this material very well for having used it for a number of mechanical applications. Having this steel to use with our Studio System will allow us to effectively continue the spread of metal additive manufacturing within the mechanical industry.’

Desktop Metal says that it plans to introduce additional core metals to its portfolio, including superalloys, carbon steels and copper.
