Fused filament fabrication of shape memory alloys

A method may include fused filament fabricating a fused filament fabricated component by delivering a softened filament to selected locations at or adjacent to a build surface. The softened filament may include a sacrificial binder and a powder including a shape memory alloy (SMA). The method also may include removing substantially all the sacrificial binder from the fused filament fabricated component to leave an unsintered component; and sintering the unsintered component to join particles of the SMA and form an SMA component.
