| Abstract Scope |
A common question in additive manufacturing (AM) is the ability to generate a uniform microstructure throughout parts. AM processes such as extrusion of a filament, jetting of materials or binders, and vat photopolymerization all build
parts layer by layer. However, after ceramic parts are printed, they must be heated in a furnace to remove any binder, and to consolidate the part through sintering, into a final ceramic. The printing and the heating processes may introduce both defects and non-uniformities. The goal of this project is to validate the uniformity of the material properties for 3D printed alumina and zirconia samples made by a lithography-based printing method. To accomplish this, the effective elastic modulus and hardness of small sections of the sample will be tested using nanoindentation. Hundreds of indentations will be made in various regions of the sample to verify that the modulus and hardness are consistent throughout the material. |
