40 Facts About Binder Jetting

What is Binder Jetting?

Binder jetting is a fascinating 3D printing technology that uses a binding agent to bond layers of powder material. This method stands out for its speed and versatility. Let's dive into some intriguing facts about binder jetting.

1. Binder jetting was first developed at the Massachusetts Institute of Technology (MIT) in the early 1990s.

2. Unlike other 3D printing methods, binder jetting doesn't use heat to fuse materials. Instead, it relies on a liquid binder.

3. The process involves spreading a thin layer of powder, then selectively depositing a binder to create a solid layer.

4. Binder jetting can use a variety of materials, including metals, ceramics, and even sand.

5. This technology is known for its ability to produce large parts quickly, making it ideal for industrial applications.

How Does Binder Jetting Work?

Understanding the mechanics of binder jetting can help appreciate its unique advantages. Here’s a closer look at how this technology operates.
