Metal Binder Jetting is an additive manufacturing process that involves printing layers of metal powder using inkjet technology followed by heating to form solid metal parts.
It addresses the need for rapid prototyping and production of metal parts with complex geometries, which are difficult or expensive to produce using traditional manufacturing methods.
Inkjet heads deposit a liquid binder onto a layer of metal powder, creating a 'green' part. This green part is then debound (removed of binder) and sintered in a furnace at high temperatures to fuse the remaining particles into a dense metal structure.
The process involves multiple steps: printing, debinding, and sintering. Each step requires specific equipment and conditions to ensure quality output.
First, a digital model is sliced into layers and sent to the printer. Inkjet heads deposit binder onto metal powder layer by layer. After printing, the green part undergoes debinding followed by sintering in an oven or furnace.
