Desktop Metal, Burlington, Massachusetts, USA, has announced the launch of 4140 chromoly steel for its Studio System™, which uses Fused Filament Fabrication (FFF) Additive Manufacturing technology for the prototyping and low-volume production of metal parts. Said to be one of the most versatile chromoly steels, 4140 is characterised by its toughness, high tensile strength, and abrasion and impact resistance, making it suitable for industrial applications.
The company stated that early applications of 4140 parts additively manufactured with the Studio System illustrate its benefits across a variety of industries, including automotive, oil and gas, pumps and hydraulics, agriculture and defence, among others.
4140 is the latest addition to the Studio System’s materials library, which also includes H13 tool steel, and 316L and 17-4 PH stainless steels. Desktop Metal plans to introduce further additional core metals to its portfolio in future, including superalloys, carbon steels and copper.
“As global demand for the Studio System grows, Desktop Metal is broadening its materials portfolio to include 4140 chromoly steel, enabling designers and engineers to print a broad variety of critical industrial applications, such as couplings, forks, pinions, pump shafts, sprockets, torsion bars, worm gears, connecting rods, and fasteners,” stated Ric Fulop, CEO and co-founder of Desktop Metal.
“Now, teams around the world will be able to leverage the Studio System to iterate quickly on 4140 prototypes and ultimately produce end-use, customer-ready parts faster and more cost-effectively.”
