What is an advantage associated with binder jetting?

Binder jetting offers a significant advantage in that support materials are not necessary during the printing process. This is primarily because the binder material acts to hold the particles of the powdered material together, allowing for complex geometries and structures to be built without needing additional support structures that would typically be required in other additive manufacturing processes. This capability not only simplifies the post-processing phase, making it easier to remove the unbound powder, but also enables the production of intricate designs that might be difficult or impossible to achieve when traditional support materials are involved.

Additionally, the absence of support structures reduces material waste and can lead to a cleaner manufacturing process without the added step of removing supports. This characteristic is particularly advantageous for applications requiring precision and complexity in the finished part. Other options, while presenting potential advantages in their own right, such as durability, production speed, or cost, do not match the unique benefit of eliminating the need for support materials that binder jetting provides.
