Is there a better alternative for Ti-6Al-4V in titanium 3D printing?

Ti-6Al-4V (Ti64) is the 'go-to' alloy for many applications, particularly in aerospace industries. But this alloy is designed for cast and wrought processes like forging and not for 3D printing (additive manufacturing). So, should we just assume Ti64 is still our best option for most applications? -Probably not. In this video I compare two titanium alloys deposited using high-deposition-rate 3D printing (additive manufacturing) - Ti-6Al-4V (Ti64) & Ti-6Al-2Sn-4Zr-2Mo-0.1Si (Ti6242) - to answer this question.
