| Abstract Scope |
Binder Jet Additive Manufacturing (BJAM) is a versatile powder bed technique that uses a binder deposited using ink jetting to form complex components. BJAM is well suited for manufacturing at scale due to its high production rates and high resolution. It has been reported that binder-particle interactions during the deposition process result in powder particles being ejected from the powder bed. However, the impact of these ejected particles on the bulk part is not well understood. We use X-Ray computed tomography to study this in H13 steel parts as printed in the green state, as well as how it subsequently impacts the debinding and sintering behavior of the material. This information will be critical for understanding the evolution of defects in sintered components and their role on material properties as well as provide insights towards sintering kinetics of H13. |
