3D printing is the disruptive manufacturing method of the 21st century. In many ways, it is inferior to traditional methods of casting and machining, because microstructure and defects are not well understood or controlled. Yet, the technique is irresistible due to its speed, simplicity, and portability. High-speed nanoindentation is a critical tool for understanding the link between microstructure, elasticity, and strength in 3D printed materials, leading to better printing and processing methods for safety and reliability. This session is a live demonstration of mapping the hardness and Young’s modulus of 3D-printed titanium. Having previously demonstrated sample preparation, Mr. Crawford demonstrates all aspects of testing, including instrument configuration, test specification, and interpretation of results.
