How to predict spreadability in powder bed based AM?

Each layer is then partially sintered or melted with an energy beam to build the parts. The layer thickness defines the vertical resolution of the printer; a thin layer leads to a better resolution...

Effect of Recycling on The Spreadability of Metallic Powder Using The GranuDrum

Many industries are already using GranuTools instruments range in different fields: additive manufacturing, food processing, pharmaceuticals, bulk material handling. The present application note is mainly focused on additive manufacturing.

Influence of Temperature on AM Metal Powders using the GranuPack, the GranuDrum and the GranuCharge

In Additive Manufacturing (AM) processes, a three-dimensional object is created one superfine layer at a time. Therefore, the term Additive Manufacturing implies adding material to create the object...
