I know the Dragonfly 2020 printer (developed by the Israeli company Nano Dimension) has been in development for quite a few years which (seems) to use the same method as described in the link. The method itself isn't even that novel since it's the same the as Stratasys' polyjet printers, only with specially formulated inks. There's probably prior art to that as well, but I know Stratasys has had polyjet printers for quite a while now.
