4140 Chromoly Steel – DM Studio System

DESKTOP METAL®

An all-purpose steel for industrial applications

4140 Chromoly Steel is characterized by its toughness, high fatigue strength, abrasion and impact resistance which makes it ideal for industrial applications. It is a low alloy steel that contains chromium, molybdenum, and manganese.

Cost-effective alloy steel for the heavy industries

With 4140 Chromoly steel, you can quickly reiterate and produce cost-effective tools and parts with complex geometries that are widely used in many applications of heavy industries such as automotive, oil and gas, agriculture or defence, printed on Studio System™, an office-friendly metal 3D printer. Having high torsional strength, 4140 can stand up to the stresses that couplings, for example, must withstand on a day-to-day basis.

Generative Piston Head

Generative Design, Prototyping 4140

Prototype piston head for a reciprocating engine, optimized with generative design. Typically CNC machined from aluminum alloy, pistons can be time-consuming and difficult to rapidly prototype and test.

Full Description

It often takes months or even years to move from design to production. With the Studio System, various piston designs can be easily prototyped and tested—speeding up product development timelines, reducing time to market, and introducing new opportunities for optimization, including generative design—all while avoiding CNC backlog and lead times.
