Perhaps given enough time it could. 3D printing in general is still rather lacking in the hobby industry. FDM/FFF isn't a terrible technology, but it does have a lot of drawbacks. It's main benefit is it can be implemented relatively cheaply and easily. The technology linked to in the paper appears to be the same (or very similar) to Stratasys' Polyjet technology and those machines go for tens of thousands of dollars on the low end. I do see this being useful for engineering teams though. Turn times on PCBs are either long or expensive and being able to quickly iterate on designs can be very valuable for a project.
