| Abstract Scope |
Metal fused filament fabrication (MFFF) is an additive manufacturing (AM) process in which filaments are fabricated from a mixture of metal powders and polymers and used these filaments for 3D printing to produce molded parts. The purpose of this study is to achieve low modulus of elasticity and superior superelastic properties. In this study, we designed filaments with a nominal composition of Ti-15Nb-5Sn (at. %) using angular elemental powders instead of spherical alloy powders, which have been studied a lot before. After 3D printing, solvent debinding, thermal debinding and sintering were performed. The properties of the sintered body were evaluated by scanning electron microscope (SEM) and compression test. The microstructure is composed of both α and β phases. The total superelastic recovered strain is 1.77% and the fracture strain and stress are 4.3% and 112.2 MPa, respectively. |
