Abstract Scope |
Additive manufacturing (AM) has allowed fabrication of intricate structures with ease compared to conventional methods. Although traditional composite structures use two or more materials, in this study Selective Laser Melting (SLM) was used to realize a composite like structure out of a single material stock. Ti64 powder was used to fabricate specimens with print patterns representing [0/90]xs and [+45/-45]xs composite configurations. Patterns were realized by varying the print parameters and cooling rates. Resulting variation in the microstructure was confirmed with hardness testing and SEM images of the sample across the printed patterns. Tensile tests combined with DIC analysis showed print patterns do influence mechanical and fracture response. On this basis, it is possible to create an additively manufactured part that shows a response like that of a composite, therefore allowing for the fabrication of parts with tailored material properties while using a single material feedstock. |
