Overview

What is Binder Jetting?

Binder Jetting is a 3D printing process in which a liquid binding agent is selectively deposited onto a bed of powder material, layer by layer, to form a solid part. This technology is used with a variety of materials, including metals, ceramics, and sand, and is known for its capability to produce complex geometries without the need for support structures.

How Binder Jetting Works

1. Design: The process starts with a 3D CAD model, which is prepared using slicing software to create a layer-by-layer plan.

2. Powder Spreading: A thin layer of powder material is spread across the build platform.

3. Binder Deposition: A print head deposits liquid binder onto the powder bed, bonding the particles together in the desired shape.

4. Layering: The process is repeated layer by layer until the entire part is complete.

5. Curing and Post-Processing: The printed part is cured to strengthen the binder, followed by sintering or infiltration to achieve final density and mechanical properties.
