Sounds like they've just slapped a fancy sounding name onto injection moulding, given that they specify a 2.5 month timeline for tooling.
That said, it's likely a novel implementation of injection moulding technique for this particular application, and so I don't mean to sound like I'm denigrating it - but it doesn't seem accurate to frame it as a successor to 3D printing (as the original HN title did).
Edit: relevant patents assigned to the founder of the Kickstarter campaign - WO1994016911A1, WO1995004666A1; this is definitely injection moulding
