T
he build materials in most 3D printing processes fall into three categories: solid filaments, solid particles as powders or
in suspensions, or liquids that can be solidified. From these materials, parts are constructed to meet the performance
requirements defined by the product use. The part performance depends not only on the build material compositions
and property, the designed geometry of the part, but also on the microstructure within the part. In 3D printing, besides
microstructures in the build materials, the print process and path of material delivery also drive the formation of additional
microstructures. The microstructure within the printed part can take on three forms. The first depends on the characteristics
of the material which make up the smallest build unit (a voxel), such as a powder volume created by a drop of glue from the
binder jetting printing. The second comes from the path that generates the progressive, layer-by-layer assembly of voxels. The
last form is the intentionally designed tunable structures. The ability of placing a different material in each physical voxel will
allow the construction of a part that may have a “continuum” of properties that range between the constituent materials. This
presentation will discuss the different material microstructures resulted from 3D print processes and the methods we have
developed to study these microstructures.
Biography
Shu Chang holds the Melbert B Cary Jr. Distinguished Professorship in the College of Imaging Arts and Sciences at the Rochester Institute of Technology (RIT),
USA. Her research applies techniques from digital printing to the rapidly growing field of print for fabrication. She has focused on quantifying the material properties
and the additive manufacturing process capabilities. Prior to RIT, she was in the print industry for more than two decades. She holds 27 US patents as well as
54 professional publications. She received her PhD in Materials Science and Engineering from the University of Minnesota, USA. She is interested in 3D printing
materials, 3d printing resolution, 3d printing quality control and prediction.
