Binder Jet Pulver
Innehållsförteckning
Binder jetting is an advanced manufacturing technology that’s been making waves in the world of additive manufacturing. This technology has the power to transform how we produce complex metal parts, from automotive components to intricate jewelry designs. But what exactly is binder jet powder, and why is it so revolutionary? Let’s dive deep into this fascinating topic.
Overview of Binder Jet Powder
Binder jet powder is the foundational material used in binder jetting technology. Unlike traditional manufacturing methods that remove material to create parts, binder jetting builds parts layer by layer, using a binder to glue powder particles together. This method offers incredible design flexibility, reduced waste, and the ability to create parts with complex geometries that are otherwise impossible to manufacture.
