| Abstract Scope |
Binderjet additive manufacturing process has grown from an innovative rapid prototyping method to a commercial manufacturing process in the past 30 years. The process relies on the inkjet printing technologies, which allow for deposition of organic binding agents in layers of a loose powder bed to create a green shape that can be subsequently sintered into a dense article. Metallic powder feedstock is typically gas atomized and the characteristics are optimized for flowability and sinterability. Recent work in the past few years has demonstrated that a sub-optimal powder flowability improves the resistance to particle ejection due to droplet impact. This presentation will discuss engineered powder characteristics and the interdependence between dispensing, spreading, powder ejection, green strength and sintering on microstructure, mechanical properties, and dimensional control. |
