As additive manufacturing reshapes industries from aerospace and automotive to medical devices and consumer products, technologies like binder jetting are leading the next evolution of 3D printing. Unlike the more familiar extrusion-based systems or laser-powered fusion technologies, this takes a radically different approach. It enables high-speed production, large-scale printing, and material flexibility while significantly reducing energy consumption and manufacturing costs. As organizations push toward faster prototyping, mass customization, and complex geometry production, it has become one of the most attractive solutions in the industry.
Binder jetting stands out because it doesn’t rely on melting or sintering during the printing stage. Instead, it uses a liquid binding agent to “glue” powder particles together layer by layer. This approach allows manufacturers to print intricate shapes using metals, sand, ceramics, composites, or even biomaterials. Whether you work in engineering, research, manufacturing, product design, or are simply curious about advanced 3D printing technologies, understanding binder jetting is essential for navigating today’s high-tech manufacturing landscape.
This comprehensive glossary dives into everything you need to know about how binder jetting works, its advantages, limitations, applications, terminologies, post-processing requirements, and industry use cases. By the end, you’ll have a deep and practical understanding of why binder jetting is becoming a manufacturing game-changer.
This is an additive manufacturing technology in which a liquid binding agent selectively adheres powder particles together layer by layer to form solid parts. It is classified under powder-bed 3D printing and differs from processes like Selective Laser Sintering (SLS) or Selective Laser Melting (SLM) because it does not use lasers or heat during printing.
This is used for metal parts, sand molds, ceramic components, and full-color prototypes.
It technology originated in the early 1990s at the Massachusetts Institute of Technology (MIT). The goal was to develop a fast, cost-effective alternative to existing additive manufacturing methods. It quickly attracted industry interest for its speed and scalability.
This continues to evolve with innovations in powder materials, binders, and industrial-scale printers.

It follows a clear and systematic process.
A thin layer of powder is spread onto the build platform using a recoater or roller.
Printheads jet microscopic droplets of binder onto selected areas of the powder bed, bonding the particles.
The build platform lowers, and new powder is spread. The process repeats layer by layer.
When printing finishes, the entire build volume contains the part surrounded by loose powder.
Excess powder is removed.
Depending on the material, parts may undergo:
Holds the material for each layer.
Spreads thin, even layers of powder.
Deposits binder droplets with high precision.
Lowers after each layer is printed.
Stores the liquid binding agent.
Extracts unbound powder after printing.
Furnaces, infiltrators, curing systems.
This is flexible, supporting a wide range of powders.

Less common but emerging in research.
Used for detailed models and prototypes.
