Seems they're taking the quick spool valve approach and refining it !

^buddy working for an R&D contract which is super top secret kept it simple and told me that basically what they do is heat the metal to the point where it melts, maintains the liquid under extremely high pressure to force it to stay liquefied, then using a complex and calculated system they pour the liquid and cool it instantly to form the shape....the same way they do with the plastic resin material. He assured me the technology exists and it is crazy but that the legal aspect of this with patents and such are whats holding back the big 3D printing boom. They already build houses in Chinese villages using huge 3D printers and cement/ash/concrete resin....neat stuff

It looks like the Koeeenniggsssegg are basically refining the quick spool valve ! But very interesting they also create distinctly shaped flow paths through the scroll too.

Either way, 3D printing is amazing...but equally the applications of 3D printing and the intricate shapes it allows

One of the problems with additive manufacturing like 3D printing is there is no specs and standards developed like the tried and true machining methods so a lot of industry is slow to adopt. While testing has showed that the material maintains 98% of its properties compared to the raw material, simple things like humidity in the booth can warp the part and screw you. There are a lot of things that can really benefit from this manufacturing method because it greatly reduces waste. There is however limits in the complexity of some of the parts and impossible to get rid of all the secondary machining in most cases. BUT it does greatly reduce waste and can get you most of the way there. It is pretyt exciting stuff and as more and more companies adopt it, specs and standards will soon follow.
