What is 3DP Binder Jetting?

3DP (3D Printing) is actually the name used for the original Binder Jetting patent licensed by ExOne. 3DP Binder Jetting is capable of printing a variety of materials including ceramics. Some materials, like sand, require no additional processing. Other materials are typically cured and sintered and sometimes infiltrated with another material, depending on the application. Hot isostatic pressing may be employed to achieve high densities in solid metals. Binder Jetting also has the ability to print very large objects.

AdvantagesDisadvantages
  • Very large size capabilities
  • High cost of systems
  • Very high production speed
  • No technical ceramics support
  • Ability to process a wide range of materials
  • Increased competition from HP, GE, Desktop Metal

How does 3DP work?

3DP Binder Jetting is an additive manufacturing process in which a liquid binding agent is selectively deposited to join powder particles. Layers of material are then bonded to form an object. The printhead strategically drops binder into the powder. The job box lowers and another layer of powder is then spread and binder is added. Over time, the part develops through the layering of powder and binder.
