Abstract Scope |
Binder-jet 3D printing as a non-beam based additive manufacturing technique exhibits very high porosity in the green, as-printed state. Using post-print heat treatments, structures with densities from 40% to over 99% can be produced that have very different microstructures and properties and, therefore, very different applications. While fully dense structures are favorable for most mechanically focused applications, structures with predictable and tailorable porosity may be useful in filtration, heat transfer and functional materials applications. In this talk, we will discuss different approaches to achieving near full density of binder jetted metallic structures and compare their properties to bulk materials. Furthermore, we will discuss partially densified binder jetted materials and properties related to their intended function in air filtration and as functional magnetic materials. |
