The Future of Metal 3D Printing
We are your metallurgical solutions partner for volume production of complex parts in metal Binder Jetting. We are equipped with the most advanced binder jetting systems and a fleet of metallurgy equipment so you can print and process more efficiently.
Printing components with increased complexity, like internal features, undercuts and channels.
Binder Jetting fits for a broad range of part sizes, especially those typically made through investment casting - with better properties and surface finish without the tooling.
Making volume production in metal 3D printing possible with in-house equipment to support every step of the process.
What is Metal Binder Jetting?
The fastest method for 3D printing in volume production
HOW IT WORKS:
An industrial printhead selectively deposits a liquid binding agent onto a thin layer of metal powder particles to build high-value and one-of-a-kind parts and tooling. The process is repeated layer by layer, using a map from a digital design file, until the object is complete. Metal materials are cured and sintered after printing to achieve densities greater than 97%, in line with metal injection molding (MIM) and better than investment castings.
WHY BINDER JETTING:
- Quick print speeds for volume production output
- Parts with internal geometries
- Freedom for complex designs
- Larger sized components for production
- No required initial tooling or retooling

In-House Metallurgy Processes
Our facility is stacked with high temperature powder metallurgy processing needed to make high volume Binder Jetting possible.
We have the world's largest installed capacity of high temperature sintering furnaces - a core process step needed for metal Binder Jetting.
With over 40 years of metallurgy experience, we bring an infrastructure of processes and equipment to support volume production of additive manufacturing from pre to post production.
From surface finish to machining, 3D printed metal parts with complex geometries can be designed, printed and shipped all in one place: At SSI Sintered Specialties.
Metal Binder Jetting: Design Features
Reduced Support Structures
Binder Jetting minimizes the support structures needed by using the powder bed itself to support the part while printing. Sinter support structures can also be printed at the same time - separate from the part - to reduce the need for support structure removal after printing and sintering.
To ensure part accuracy, we have the ability to manage shrinkage during sintering. Also, post-sintering secondary operations can support qualifying key dimensions and addressing surface finish requirements.
Binder Jetting supports light-weighting not only by controlling the fill ratio through lattice structures, but also by providing a porous initial structure that can be sintered to maintain the porous structure, infiltrated to create a composite structure, or sintered to high density.
Binder Jetting print speeds are much faster than competing additive processes, opening the door for the possibility of higher volumes and more cost-competitive finished parts.
Because of the process's capabilities to support parts through sintering and control distortion, Binder Jetting allows for design freedom to create undercuts, complex internal channels, lattices, sharp edges and corners, surface textures, and fine features.
With the ability for iterative design changes in a single build, Binder Jetting eliminates the need for expensive upfront tooling costs and retooling - significantly reducing lead times.
Binder Jetting excels at producing parts with internal geometries as the powder acts as the support structure to the internal cavities and is easy to remove as long as there is some open passageway to the surface.
Thinner Wall Thickness
Thinner wall thicknesses aid in the removal of the binder prior to sintering, and more uniform wall thicknesses minimize the potential for distortion and cracking during sintering.
