Numerical simulation and experimental investigation of cavity filling in powder injection rapid prototyping process

Cavity filling of a powder-binder mixture is a crucial stage in a newly proposed powder injection rapid prototyping (PIRP) and powder injection molding (PIM) processes, in which a metallic or ceramic powder-binder mixture is heated and injected into a mold cavity to create a solid layer of a green p...
