DESKTOP METAL®
Nickel Alloy IN625
Alloy 625. A nickel-chromium super alloy
Alloy 625 is a nickel-chromium superalloy. It is known for its high strength, outstanding corrosion resistance, and ability to withstand extreme temperatures.
Inconel 625. The superalloy for heavy industries
IN625 has excellent mechanical properties such as high strength, great weldability, corrosion and oxidation resistance. In addition, it also has the ability to hold up under extreme, elevated temperatures and pressures for parts under load. Together with the binder jetting technology of the Production System, this superalloy is ideal for manufacturing parts required by heavy industries such as aerospace, power generation, marine, and chemical processing.

Hydraulic Spool (DM Production System)
Material: IN625 Nickel Alloy
Hydraulic spools are used in the oil & gas industry. They assist in adjusting the flow rates of control valves. IN625 is an essential material for these spools to ensure longevity and withstand highly corrosive environments in oil & gas.
Full Description
When such parts are produced using traditional manufacturing methods, the spools must typically be assembled from several machined components. With Production System technology, each hydraulic spool can be consolidated and printed as a single part instead of multiple components, significantly reducing the assembly labour costs as thousands can be printed at once with no user input.
Technology/Process
- Single Pass Jetting™ (SPJ) Technology
Four-Way Valve Housing (DM Production System)
Material: IN625 Nickel Alloy
Valve bodies used in power plants to process corrosive fluids often feature complex internal features which makes them difficult or impossible to manufacture as single components using conventional manufacturing processes.
Full Description
IN625 is a critical material for these housings because of its durability and corrosion resistance. Binder jetting this component using Production System SPJ technology enables assembly consolidation, reducing the part count, assembly labour time, and cost to produce the housing.
Technology/Process
- Single Pass Jetting™ (SPJ) Technology
Internal Combustion Block (DM Production System)
Material: IN625 Nickel Alloy
Internal combustion blocks used in aircraft engines often feature extremely complex geometries that are outside the ability of most machine shops and require multiple machining setups and advanced CAM programming.
Full Description
With the Production System, this part can be printed to near net shape without the need for any tooling, and the critical internal dimensions can be touched up in just a few hours with minimal machining setups needed. In addition, because this part experiences extremely high forces and temperatures during the combustion stage, IN625 is an ideal material choice for its incredible material properties in these environments.

- Single Pass Jetting™ (SPJ) Technology
Valve Plug (DM Production System)
Material: IN625 Nickel Alloy
Valve plugs are used for regulating highly-corrosive fluids in chemical processing environments, where corrosion resistance under a range of temperatures makes IN625 an excellent material choice.
Full Description
Traditionally, these parts would be produced using casting followed by a post-machining step for critical dimensions. Since IN625 is a difficult material to machine and the part has complex geometries with organic curves, the conventional manufacturing process would be very expensive with long tooling lead times. In addition, the Production System enables on-demand production of valves in numerous configurations, without the need for a unique, expensive casting tool for each configuration, greatly reducing production costs.

Turbine Blade (DM Production System)
Material: IN625 Nickel Alloy
Turbine blades are critical components used in gas or steam turbines in the aerospace industry with complex geometries that can be easily produced via binder jetting on the Production System.
Full Description
These blades are some of the most challenging components to mass produce due to their complex geometries, including organic curves that optimize aerodynamics, and complex cooling channels that ensure the blades maintain an optimal temperature. The Production System enables 3D printing of such geometries, which would otherwise be challenging to produce by traditional manufacturing methods such as advanced casting and machining techniques. IN625 is an ideal material for these blades because of its high tensile, creep, and rupture strength, fatigue and thermal-fatigue strength, and corrosion resistance.
