Binder Jet 3D Printing
Binder Jetting is an additive manufacturing process where a liquid binding agent is selectively deposited onto a powder bed to create parts layer by layer. The binding agent glues the powder particles together, forming the desired structure. After printing, the part undergoes additional processes such as curing, sintering, or infiltration to improve strength and durability
What is it?
How BJP Works
Binder jetting 3D printing relies on two primary components: a powder and a binder. The powder, which can be mineral, metal, ceramic, or any other material, is in its powder form. The binder, a liquid, serves as an adhesive between the layers of powder.
The process begins with a roller spreading a layer of powder across the build platform. Following this, the print head precisely deposits the liquid binder, which binds the powder together. After each layer is completed, the build platform is lowered by the thickness of one layer. A fresh layer of powder is then spread, and the process is repeated. The unbound powder remains in place, surrounding the printed object.
